I am running a Windows 2003 Native Active Directory.  I recently installed a Windows 2008 Server.  I preped the forest, domain, and promoted the Windows 2008 server to a domain controller.  The Windows 2008 domain controller runs fine, but after a few hours or days, it stops accepting UNC request from pre Windows 2008 server.  If I try to map using UNC from a prep Windows 2008, it never responds and never errors out.  If I try to map from a Windows 2008 server, it responds without any problems.  When I reboot the Windows 2008 domain controller everything will work fine for a few hours or days and after that it will act up again.  There's no error messages in the application or system logs to point me in the correct direction.  I know this problem is somehow associated with SMB compatibility issues.  Windows 2008 uses SMB2 while Windows 2003 and older uses SMB1.  Any info in this matter is very much appreciated.  Thanks in advance.
