Problems accessing file shares on Windows Server 2008 64-bit running Symantec Endpoint Protection
Why are Windows XP and Vista clients losing connectivity to Windows Server 2008 64-bit file shares and DFS shares?
Windows XP and Vista clients lose connectivity to Windows Server 2008 64-bit file shares and DFS shares after a period of time when the server is under load during production hours. The Windows Server 2008 itself does appear to be working and does not show any signs of a deadlock. This issue was reported on Symantec Endpoint Protection MR3 and MR4.
This problem is fixed in Symantec Endpoint Protection 11.0.4202.75 (MR4 MP2) or later.

Okay so remind me again what Antivirus really does other than….
1. Lull me into a false sense of security
2. Make me think it’s doing something when instead it’s causing problems on my network that I blame on something else
If you use antivirus on your SBS 2008, make sure you are on a version you’ve tested, set up the necessary exclusions so that it doesn’t scan stuff it shouldn’t, and make sure you are on a version that isn’t nailing your server.
