Hi
We have a Windows 2008 Storage Server that we use as a data server. About 100 folders are shared on our network and we use DFS to collect these shares into manageable shared units.
The network comprises 35 Windows 7 clients and one Vista client and a couple of XP machines. These are on a Windows Active Directory that presently comprises three domain controllers: 2003, 2008 and 2012 R2. The network comprises just one site and one subnet.
This setup has worked fine for many years (we've had an Active Directory domain since 2001).
As soon as I replaced our Windows XP clients with the Windows 7 clients I have been seeing some strange network issues.
The most bizarre, and the most unwelcome is that when staff try to create new folders or rename existing ones they will sometimes not be allowed to. The problem is intermittent and I have no idea what may be causing it.
The folder rename issue was encountered when we still used XP but I fixed that by disabling the caching of thumbnails. The error message that appears states the folder is in use. I have used Computer Management on the storage server and looked at Shared Folders > Open Files and have determined that no files were open when this issue occurred.
When staff are unable to create a new folder they see the following message:
I have tried various things to troubleshoot this with the help of a TechNet Community Support person in the Windows 7 forums here.
To summarise we have tried using Process Monitor to capture the events and I am quite happy to upload this if anyone would like to see it.
We tried the registry edits detailed in this MS article.
I have created a dedicated firewall rule that allows all traffic on TCP ports 137, 138, 139 and 445.
Another respondent suggested checking out Slow-Link mode but this has not been triggered.
Does anyone have any ideas what may be causing this, please? The network worked like a dream before the Windows 7 clients were introduced, when XP was used.
Thanks!
