Wireshark doesn't show aes-128-gcm encryption being used after being negotiated
On a windows 2019 server I setup a samba connection to it's own SYSVOL and captured the connection with Wireshark. What I see is a Negotiate request with both aes-128-ccm and aes-128-gcm as supported encryption capabilities and the Negotiate Response shows:
Negotiate Context: SMB2_ENCRYPTION_CAPABILITIES
Type: SMB2_ENCRYPTION_CAPABILITIES (0x0002)
DataLength: 4
Reserved: 00000000
CipherCount: 1
CipherId: AES-128-GCM (0x0002)
The server/client has negotiated GCM support at this point. Yet the very first packet of smb3 encrypted traffic (and all SMB3 encrypted traffic) after this point shows it using CCM.
SMB2 (Server Message Block Protocol version 2)
SMB2 Transform Header
ProtocolId: 0xfd534d42
Signature: 44373ca8a6f5cdf262bfcba36b78f8f8
Nonce: f36785660c5980c00100000000000000
Message size: 134
Reserved: 0000
Encryption ALG: AES-128-CCM (0x0001)
Why does wireshark show the traffic as being encrypted as aes-128-ccm instead of the negotiated aes-128-gcm? Is this a bug in Windows 2019 or in Wireshark?
2-Node S2D Failover Cluster and CAU
Hi guys,
I have 2-Node S2D Failover Cluster built on Dell PowerEdge R720xd.
The operating system on both nodes is Windwos Server 2016 Datacenter.
I configured and run CAU but hardly one of the nodes was restarted I got this.
CAU itself seems runs fine.
I'm just wondering if CAU or any other way of patching works with 2-Node S2D failover Cluster or no matter how it is done it affects storage.

Temporary loss of access to root of Home folder when moving file or creating new folder
We have begun to experience a very obnoxious problem with Windows 10 workstations in relation to the root users' Home folders defined via the AD user profile.
Environment: users have their Home folder defined to connect H: to \\ServerName\HiddenShareName$\UserID. The have other drives mapped via login script. The server hosting the Home folders is our Server 20120 R2 DC.
Problem: every time a user moves a file out of their Home folder (right-click, drag, then Move), the Home folder disconnects for a few seconds. Even as Domain Admin, if I right-click a file in my Home folder, drag it to my local desktop, release and click Move, the file correctly moves, and the Home folder no longer shows that file. All looks good on the surface unless/until I actually try to access the root of the Home folder.
1. I click inside the right pane in Explorer and press F5. I get a dialog box indicating that "H:\ is unavailable. If this location is on this PC, blah, blah, blah" That last part is a paraphrase:). When I close that message, the H: drive
is there but appears blank (no content) with a comment "Working on it..." I can even drag another file into it at this point, and it will show me only that file, not the pre-existing contents. But the original contents never appear unless/until I
refresh.
2. I can continue to access files on my H: drive via shortcuts even while the drive indicates it is inaccessible..
3. I can double-click and open some files but not others. I put a .png and .txt file in my home folder. I moved another file out, then quickly double-click the .png file. It opens. But when I double-click the .txt file, I get this: "H:\FileName.txt. The
directory name is invalid". If I go fast enough, I even get the error attempting open a .txt file, open the .png successfully, then get the error on the .txt file again.
4. I can even open a command prompt, go to H:, enter Dir [Enter], and see the contents of H:. But then I move a file out of my Home folder, go immediately back into that same CMD window, and enter Dir [Enter] again. This time, it says "The system cannot
find the file specified." I wait a few seconds, Dir again, and now I again get the contents of H:
5. I can access any subfolders by double-clicking during the failure, but when it opens, if I click the Back button, it tells me H: is unavailable. This is definitely something to do with the root of the Home folder only.
6. The same thing happens if I create a new subfolder. For a few seconds, the root of the Home folder becomes unavailable. I can even immediately double-click the new folder to get into it, but then try to go back and be denied.
In any of the above cases, when I wait a few seconds and then try again, I can read the root H: drive, open files from it, etc.
This is a big problem because we have a core business application that imports files from users' home folders, then moves those files once imported. It regularly loses its path to H: after processing a job, and the user has to re-point it to H: again.
Additional germane facts.
1. This occurs only on Windows 10. I have been unable to reproduce it on Windows 7 or from any of our servers having the sam drive-mapping methodologies.
2. This does not happen if the user deletes a file from the home folder instead of moving the file.
3. This does not happen if I move a file into the H: drive.
4. This does not occur with any other drives mapped via logon script.
5. The problem does not occur if I disconnect the Home folder drive, then reconnect manually by "Map network drive" or "net use" to the same path & drive letter. It is very specific to the Home folder mapping.
6. It is not specific to H:. I changed my admin profile to connect home as W: instead of H:, and the same thing happens.
7. It does not happen within subfolders of the Home folder, nor does moving a file from a subfolder deny me access to the root.
8. It does not happen when I move a folder out of H:, only when I move a file out of H:.
We already rebooted the DC and workstations since the problem began, with no effect.

File service delays, pauses and performance issues
Something has changed in our environment over the past year and suddenly any file driven activities/functions are being negatively impacted from a performance standpoint. Here are some things i have observed lately in our environment.
Windows 10 client copies a zip file from the local C: drive to a Windows 2016 server via the UNC admin share path (e.g. \\server\c$\temp\). You see the file copy status window immediately, but the status sits there at 0% for a minute before it starts progressing with the file copy at a normal quick pace.
You empty your recycle bin on a file server. The status bar hangs at a certain percentage for over a minute and then starts progress at a normal pace.
You right click a file in File Explorer. It takes almost a minute for the menu to show up. Once it does, everything works fine.
You install an upgrade to a server application. The upgrade takes 10 times as long as it seems like file activities are taking forever.
You update the security on a folder. Each file is updated with the new security settings, but instead of it happening fast, you see it taking a long time, one file at a time.
These are all different clients and servers i'm seeing this behavior on, so its not just one machine. I dont even know where to start or what to put in my 'suspect list'. Is it a Windows setting? Is it a bug? Is it virus protection? or Windows security settings conflicting with virus protection? Is it something else? how would i even start with troubleshooting this?
storage spaces volume recommendations
I have a Storage Pool with more than 400 TB, using "virtual disks" presented by IDRAC (the RAID 6 was created in DELL IDRAC) that Windows see as Physical disks with 42 TB and 17 TB SSD in the same Storage Pool.
I want to create volumes, have you some "size recommendation" about the volumes? I want to create volumes NTFS with 64TB size, the Operative System is Windows Storage Server 2016, the server have configured DFS synchronization with another identical server in another place
Based in your experiences, can I create "stable" volumes NTFS with 64TB size?
Thanks in advance
Storage Spaces simple parity - add another column set, double the parity as well?
Hello,
I am running an eight drive simple parity (column size = 8) vdisk, and would like to double the size by adding another 8 hard drives to the same vdisk.
Will I have another parity disk as a result of this (meaning: one disk can fail from both "column sets") or will the new 16 drive partition still only tolerate a single disk fault?
Upgrading Storage Pool from 6 Disk, 3 column, Parity, Fixed, 1 Disk redundancy... to 12 Disk, 3 column, Parity, Fixed, 2 Disk redundancy...
Hello all,
I have been using a storage space under Windows Server 2016 standard x64 for a few years now and have had wonderful results.
When first setting up the Pool I opted for 2 x 2TB disks and used recommended settings from there, as time has gone on the pool size has grown (As it always does) and additional disks of the same size have been added (first disk 3 & 4, and then later Disk 5 & 6).
I recently discovered that my Pool was only 1 disk redundant when I had thought it was 2 disk after adding disk 3 & 4.
The pool is reaching its upper limit of capacity and this means again adding more disk's. I would be happy with expanding it to a maximum of 12 disk's as that's the capacity of the physical chassis I've been provided. I am wondering if while doing this the pool can be converted to 2 disk redundancy or do I have to create a completely separate 12 disk pool with 2 disk settings and copy everything to it and then abandon the old pool.
Thank you in advance for any advice that can be offered.
Partition Issue
Hello!
I installed Windows Server 2019 eval edition to do some testing. I think I made a mistake since I wasn't able to use all my available disk space.
Now I'm trying to reclaim this space and add it to my S:\ partition. How can I do this? I tried using the GUI disk management tool but I can't seem to do what I want. I was reading about the 2GB limit on partitions and I think that's what has happened. Looking for some advice. Thanks!

Windows Server 2012 Shared Folder
Hi,
I am using windows server 2012, setup some shared folders for different group to access the different folder. It works for a while, however, after sometime, the shared folder suddenly can be access by everyone.
Can anyone share how to solve this problem?
Mapped network drives disconnect after some time
Hello everybody,
A customer is running Windows Server 2019 Terminal and File servers. The terminal servers map network drives to a file share on the file server. We have problems with two applications, because the network drives are in a disconnected state after some time:
- One has an Access database residing on the file server, accessed from several users. Access crashes on disconnect because its file handles to the database file do not work any longer.
- A .net desktop application is used and its .exe and .dll reside on the file server. The users start the .exe from the mapped drive. When the mapped drives goes into the disconnected state, and the application needs to load something from one of its DLLs, the application crashes with an unhandled exception. The event log says that the .net runtime could not continue because the network connection was disconnected.
We have followed https://support.microsoft.com/en-us/help/297684/mapped-drive-connection-to-network-share-may-be-lost and set the LanManServer parameters to disconnect after 5000 instead of 15 minutes (on the file server), and set the LanManWorkstaition parameters to disconnect after 65535 instead of 600 seconds (on the terminal servers). But this did _not_ help.
I guess we do not need to discuss whether Access databases are fantastic or file servers are fantastic or running .exes from file shares is fantastic ;-) The question is simple:What can we do to keep the network drives connected, please?
Best Regards, Stefan Falk
Remotely Configuring Shadow Copies
I start the Computer Management MMC.
Connect to the computer I want to manage.
Right click on Shared Folders under system tools.
Select All Tasks/Configure Shadow Copies.
The Shadow Copies dialog comes up and has Initialization Failed Error 0x800706ba: The RPC server is unavailable.
Any suggestions? I've tried searching both the internet and microsoft sites to get an answer. I was able to configure it by logging on to the machine directly, but our goal is to do everything from a single computer and not log on to each file server.
Thanks.

Server 2019 - Event ID 10000 - Unable to start a DCOM Server {9C38ED61-D565-4728-AEEE-C80952F0ECDE}
Problem:
This error is periodically recorded in the System event log:
Event ID: 10000
Source: DistributedCOM
Event Data: Unable to start a DCOM Server: {9C38ED61-D565-4728-AEEE-C80952F0ECDE}. The error: "0" Happened while starting this command: C:\Windows\System32\vdsldr.exe -Embedding
This error appears when DFS-R is installed, when the computer is rebooted, every time the DFS-R service is started, and whenever application aware checkpoint-based backups are taken.
Simple reproduction steps:
- On a clean computer or VM, boot from the Microsoft-provided Windows Server 2019 media. I used SW_DVD9_Win_Server_STD_CORE_2019_1809.1_64Bit_English_DC_STD_MLF_X22-02970.ISO from the Volume Licensing website.
- Install Windows Server 2019
- Install DFS-R using PowerShell: Install-WindowsFeature -Name FS-DFS-Replication
- Error will now be present in Event Log: Get-EventLog -LogName System -EntryType Error -Source DCOM
- Restarting the computer, or just restarting the DFS-R service, will cause another error to be added to the event log.
Notes:
- Problem affects Core and Desktop Experience
- Problem affects Standard and Datacenter
- As of 2019-Sep-17, installing Windows Updates doesn't make a difference
- Joining a domain, or not, makes no difference
- Properly configuring DFS Replication does not make a difference
Request:
This issue is related to another TechNet question, but there's no answer there.
I thinkit's ignorable, but I don't really know. I would like to "fix" whatever is causing this error. Or, at least get some authoritative comments that it is safe to ignore, and preferably have someone at Microsoft correct the problem that is leading to an ignorable error.
Any and all help would be appreciated. Thank you.

Some users are getting "Location not available" on DFS namespace
This morning I migrated my company to a new file server and am seeing some issues.
- I have three shares set up on the file server: Groups, Home and Public
- On Groups and Home I have access based enumeration set up and all the sub folders have the proper group permissions
- I have set up the DFS namespace as \\companydomain\namespace
- I have a drive letter (G:) mapped via GPO to the namespace
So for my test account and for most users, everything seems to work as it should. When they open the G: drive they see the three shares and when opening them they see the folders they are supposed to.
However, I have a couple users that when they click on GROUPS or HOME they get an error that "Location is not available". If I check the effective access on the share for that user they have read permissions.
Couple things...
- She can get into PUBLIC normally but its not set up the same as the other two folders with Access based enumeration. Essentially everyone maps that drive equally.
- I had the user log into a test VM and the user COULD access the G:\Groups and G:\HOME share normally and see the folders they have access to.
- I logged on to her PC with my elevated account and it worked fine for me
- I found that she WAS able to directly pull up G:\Groups\<subfolder> so as a workaround I made a few shortcuts on her desktop to the folders she has access to.
- One of the users was able to get into everything normally when she first signed on and then after an hour started to get that error.
Could this be a profile issue? Not sure where to begin on this... Thanks in advance
DFS Namespce and ADSI Edit problem
Hi guys, I had a problem since last week with my domain controller servers DC1 and DC2. I noticed that they werent synchronizing. Im using DFS .
with more detection I was able to get files to copied from DC2 shared folder to DC1 folder but not from DC1 to DC2
upon further looking into the issue i noticed that in DFS Management Namespace had red X and when i click on it I got an error saying \\domain.com\namespace: The namespace cannot be queried. There is no such object on the server.
So i search more and came across this page. https://techjourney.net/dfs-namespace-cannot-be-queried-error-remove-delete-orphaned-namespace/
I followed it to my demise and did what it said without knowing the outcome. I went to ADSI Edit and i deleted the objects in the CN=Dfs-Configuration folder. when I did that the namespace on DC1 server also started having redx on it.
Can someone help me what I can do. I can still create a new namespace but I need to create namespace with same exact name.
Thanks in advace

How do I get from a disk number in Event Viewer to a PhysicalDisk in powershell?
I am getting a notice in Event Viewer: The IO operation at logical block address 0x9a83a19 for Disk 3 (PDO name: \Device\00000033) was retried.
I want to find the Physical Disk that "Disk 3" represents. I can't find it with Get-Disk because it is a member of a Storage Spaces Pool. I have been unable to find any path of PowerShell commands that can get me from "Disk 3" to a MSFT_PhysicalDisk so I can identify which disk is "Disk 3." Any Ideas?
DFS STORAGE ALMOST FULL CAUSES BY CONFLICTANDDELETED FOLDER
Hello Everyone,
I have a Windows server which have a DFS storage of 1800 GB, unfortunately it became full due to conflictanddeleted folder which occupies 1000 GB already.
What is the resolution to this? And do I need to just delete it? Or any action that will help this issue
Thank you very much.
