Request help to understand DDEVAL report

Dear All,

While running the DDEVAL tool, it gives a result with "no compression". I want some help on what to derive from values shown against "no compression".

There comes different types of understanding from different forums about this term, which is not concluding to one answer.

Can somebody provide actual understanding of this term while reported by DDEVAL tool?

Thanks,

Amit Jogi

LanmanWorkstation on DC

I noticed that my DCs (4 out of 6) LanmanWorkstation EnableSecuritySignature is disabled, set to 0.  Can this have an effect on shares on other servers? Could this have a negative effect on all SMB traffic?

Running Windows 2012 Server with Active Directory File / Authentication services -- external storage question

I'm running windows server 2012 deployed with active directory authentication. Very simplistic:

1) Shared volume, ( Accounting ), local users mount \\ip\share\ using auth via AD

Does anyone have any experience with utilizing a mapped/mounted/network drive ( meaning the AD server is actually the client mounting a \\ip\\share from another server via SMB/NFS/CIFS ) within the AD deployment? Like from a ubuntu SMB server on the local network.

Thank you

LMCompatibilityLevel Mismatch

help desk put out a GPO that set LMCompatibilityLevel to 5.  My our servers the regkey is missing on 2012R2 and 2016 servers.  This means the LMCompatibilityLevel for my servers is 3 correct?  where does it get 3 from if the regkey is not there?  Also this would NOT be a mismatch correct?

Windows Search indexing not working properly

Dear all,

When I try to search for a document content on an indexed location it will not display any results, but you can clearly see that this text is existing in the word document. See screenshot. This is not for all but for a lot of "in document text searches"

The server where the files are stored is a Server 2016.

The problem exists when I search the local drive directly on the server, and when I search from a windows 10 clients on the mapped network drive

- Restart of service did not fix the issue

- Troubleshooting could not identify the problem

- Rebulding the search index on the server did not solve the problem

- Regedit "Setup Completed Successfully" set to 0, reset the index and did not solve the problem

Do you have any idea how to fix this?

I would like to provide a screenshot, but I'm not allowed to.

Kind regards

Matthias

Deduplication Problems | Garbage Collection hangs on 0%

Hello, 

Since a couple of months we have a problem with deduplication on our live production.
We have two servers (FS01 and FS02). We use DFS to replicate files between the servers. 
One server located at the office and another server located on the seccond office. 
We gott a backlog of DFS from 1 000 000 + so we decided to move the server on the same network to sync the files. 

When we start garbage collection on FS02 it works well and its finished after 4 - 6 hours. 
When we start garbage collection manual on FS01 with high priority the job start. 
Now after 3 days when i check the status its still hangs on 0%.
How we can solve this problem ? 
We already fully update the server and restarted before we start the garbage collection.

If you need any more information let me know.

Properly configuring test environment for switching print servers from Production's "print2008" to dev "print2016"

Hello - sorry if this is the wrong forum, but since it deals with printers shared over SMB, I thought it might fit in the "file services" section.

We have 500 users using \\print2008 to print right now, so I can't just stand up the new machine, \\print2016 and immediately change our DNS server to have a CNAME pointing print2008 to the new print2016 machine until I'm sure everything works.

So I thought that perhaps I could use the hosts file on my office workstation to do a simple alias.

I stick:

<ip address> print2008
<ip address>print2008.fqdn

into the hosts file and just hope it will work.

However, sadly, none of my printers previously mapped to print2008 are working on my workstation post reboot. Whenever I try to print, I get a GUI-based "access is denied error" and in Event Viewer, I get the following:

The Kerberos client received a KRB_AP_ERR_MODIFIED error from the server print2016$. The target name used was host/print2008. This indicates that the target server failed to decrypt the ticket provided by the client. This can occur when the target server principal name (SPN) is registered on an account other than the account the target service is using. Ensure that the target SPN is only registered on the account used by the server. This error can also happen if the target service account password is different than what is configured on the Kerberos Key Distribution Center for that target service. Ensure that the service on the server and the KDC are both configured to use the same password.

So, I'm guessing that for security's sake, print2016 is refusing to handle my requests because my workstation is offering them to print2008. I followed what instructions I was able to from here, like turning off StrictNameChecks and turning on DNSonWire. I also added the BackConnectionHostNames entry. Basically everything that didn't give me an error message, but I couldn't do the dreaded SPN record for kerberos authentication.... because of course, I get the "duplicate SPN found, aborting operation!" error.

Of course there's a duplicate SPN; print2008 is being used by 500 users!

If I was 100% sure that everything was working great on print2016 I'd go ahead and just make the changes in DNS, like adding the CNAME record that the link in the previous paragraph describes, but I can't riskanything happening to print2008 when it's in active use.

Can anyone recommend a good way to set up my testing environment so I can basically fool my workstation into being okay with sending "bad" kerberos tickets to print2016, and have print2016 be okay with accepting them?

Thanks.

Issues with server access that seems to be related to Shadow Copy

We are experiencing issues with server access that seems to be related to Shadow Copy. This is being seen multiple servers with anywhere from 20 to 35TB of storage at least 10TB of data on the data drive. I have been able to reproduce what I am seeing on Server 2012, Server 2016 and Server 2008.

Here is a description of what I am seeing. We have a Shadow Copy run at noon. A little after 12:05 we see access to the server appear to freeze. This goes on for about 3 to 5 minutes. During this time copy jobs, processes being run on the server and even trying to delete small files will halt/pause. Sometimes processes will crash, and we are seeing copy jobs fail as well. We will often run processes that take days to complete and copy jobs are often of multiple terabytes. It looks to me that the actual Shadow Copy job has completed when we see the freezing. That is my assumption because when I look at the Shadow Copy job in Computer Management it shows a time of 10:05 for the current job which I am assuming is the time the Shadow Copy itself completed.

In reading about Shadow Copy it does say that during the process it will freeze files in order ready the file system, but if I understand correctly that should happen at the beginning of the process and should only last few seconds and should not be allowed to last longer the 60 seconds.

During the Shadow Copy process the write I/O request remain frozen but should the process should only last 10 seconds

So I am wondering if there is an issue with the way Shadow copy is completing its task or if maybe this is to be expected due to the quantity of data on the servers.


Server 2016 File Ownership - How to keep it as "Administrators"

  1. I have a server where a service runs as a user and creates files.
    This account is under the Administrators Group (local).
  2. Later, other users under the local Administrators Group (local) need to modify, delete these files, but they can't because the user in step 1 still has ownership.
  3. I think with older servers (2008 R2) we were able to make sure no matter what the owner always remained "Administrators".
  4. How do I accomplish this in Server 2016?

User name does not match

Hi

We have Windows 2008 domain. Our file server is NetApp.

When a user tried to open a file on the file server, the user got the message something like "The file is opened by user A. You can only Read the file, you can not modify the file."

But in the file open files window on the file server, it showed user B who was opening the file. Actually user A's account has been disabled. User B is right person who was opening the file at that moment.

How come the user got the incorrect information about who was opening the file?

Please help!

Thanks in advance!

Faster SAN Performance Using Drive Letter

On Windows Server 2012 R2 (and reproduced on 2016), we see significantly faster performance from our SANs (both Compellent and SolidFire) when accessing files through a drive letter.  For example:

  1. Move-ClusterGroup to attach the storage
  2. Run WinDirStat against 43,484 directories under C:\BuildCluster\STORAGE\RootFolder: 1m 38s


Versus:

  1. Move-ClusterGroup to attach the storage
  2. Set-WmiInstance to assign a drive letter to C:\BuildCluster\STORAGE
  3. Run WinDirStat against 43,484 directories under Q:\RootFolder: 21s


Why would assigning a drive letter make file performance that much faster?  We'd actually prefer NOT to have to use a drive letter, but we can't argue against the performance gains.



Windows 10 clients cannot access shared folders on Windows Server 2008 File Server

Hi Guys

I have two file servers which are both running Windows Server 2008 R2 Standard. Currently, all Windows 7 client PCs can connect to both servers to access shared files & folders. So now the problem is; All Windows 10 client PCs are able to connect to only one of the two servers, i.e. File Server 1 but they can not connect to File Server 2.

The error message all Windows 10 client PCs receive when trying to access File Server 2 is;

"\\File-Server2 is not accessible. You might not have permission to use this network resource. Contact the administrator of this server to find out if you have access permission. 

The trust relationship between this workstation and the primary domain failed"

I have tried to re-join the Win 10 PCs to the domain but it didn't work. Why is this file server only refusing connections from Win 10 clients? I need Win 10 clients to also access the shared folders on this Server. Can anyone please assist us? Much appreciated.


How to disable / decrease MPIO cache

Hi, 

Testing out a new backup repository.

I have a QNAP nas with 12disks. It's currently connected to my aruba switch via 2x1Gbit links. My backup server is physical with 4x10k raid5, Win2012r2. The backup server also is also connected to the same switch with 2x1Gb links.

QNAP is a iscsi target, and MPIO has been enabled on the backup server.

When I copy a 50GB test file from backup to QNAP, the progress bar shows the speed of 350MB/s, which is impossible. After progress bar shows that the file is copied (after ~3mins), a good portion of the file is still in the memory of the backup server and both two nics are still transferring ~1Gbps for about two minutes after the file was supposed to be copied over. You can see the memory consumption first rising by 20GB, and then slowly lowering back to normal. In the receiving end the QNAP shows transfer speed of 200MB/s during whole time. 

Is there a some kind of built-in caching in MPIO? Is there way to disable, or significantly lower the amount of cache?


E: In devmgmt -> disk drives -> QNAP iSCSI Storage Multi-Path disk Device -> policies "Enable write caching on the device" is not checked.

Is 3-tier Storage on Single Windows 2016 Server Possible?

I have a high-end workstation that I am running Windows 2016 Server.  I have the opportunity to add 4TB of NVMe SSDs to my existing 8TB of SSD and 48TB of HDD storage.  I would like to configure this as a three tier storage NVMe (hot), SSD (warm) and HHD (cold).  Is this possible with a single server and not having multiple server nodes?

Offline files still syncing after Folder Redirection Removed

Awhile back I removed the Folder Redirection GPO because of numerous issues with offline files. Recently I noticed the User Data Folder still had one users data in it. And I found that his outlook archive located here Data\Username\documents\.sync\Archive\Outlook Files was full of incremented archive pst files totaling 375GB which is syncing multiple times a day. Any idea whats going on and how to correct it?

Also is there away to backup users my documents to the server without folder redirection. Maybe something that uses shadow copies stored on the server.
