We recently moved a large group of files from a Windows 2003 server to a Windows 2008 server. These files are accessed by many users constantly throughout the day, so they are almost always considered open. When those files were residing on the Windows 2003 server, any user or server could access those files even though they were open and make changes to them.
Since we moved the files from the 2003 server to the 2008 server the only users/servers that can still access and change those files while they are open are:
Windows 7 users
Windows Server 2008 server
Windows Server 2012 server
The servers that cannot access/change those files are:
Windows 2000 server
Windows 2003 server
Every time one of those servers try to access the file (or even just change the name of an open file for testing purposes) we get the following error:
Cannot rename <file name>: There has been a sharing violation. The Source or destination file may be in use.
We have tried the following to resolve it:
Verified all the permissions/shares are identical for the files on the Server 2003 and the Server 2008.
Changed the NTLM acceptance level on the Windows 2008 server by: Go to: Local Policies > Security OptionsFind "Network Security: LAN Manager authentication level" Change Setting from "Send NTLMv2 response only" to "Send LM & NTLM - use NTLMv2 session security if negotiated"
Verified the times are identical on all servers.
Removed one Windows 2003 server from the domain and re-joined it again after the NTLM change.
The problem still exists. Can anyone recommend a solution?
