Server 2008 w/AD lose SMB access

One of my domain controllers (AD1) stops allowing SMB access.  (e.g. \\ad1\whatever)

I can't figure out what/why this is happening.  I see nothing in the Windows Logs that relates to this.

Any ideas?  If you try to go to \\ad1\ it never opens.  If I restart the server it works again for about a day.

What AV are running? This has been happening with some AV softwares like Symantec Endpoint and the fix is to fully remove the product. Disable TCP Checksum and IP Checksum or TCP Offload.

The AV is Symantec AntiVirus.

I have been working on a forefront solution to replace the Symantec one though.  I can uninstall it and see if works tomorrow.

Simplify Active Directory Administration

Administration of Active Directory does not have to be hard.  Too often what should be a simple task is made more difficult than it needs to be.The solution?  Hyena from SystemTools Software.  With ease-of-use as well as powerful importing and bulk updating capabilities.

This is going to be your issue. Get the cleanwipe tool to fully remove SEP from your system because just uninstalling it will leave registry keys still place which causes issues. MS Forefront is a OK solution but McAfee Total Protection has been great on 2008 servers and clients. The product is actually not really expensive.
