I have a new Windows 2008 R2 Server. I have created shares for users home directories. After a few days it just stops sharing via DNS or Netbios to ALL XP and 2003 clients. I can access the shares from the server itself but not from My Network places, the command line or Active Directory on any other station.It is a Domain Controller, runs DNS and I have no idea why all of a sudden it just stops sharing. It doesn't have anything but the basics and Norton Corporate 10 client (which seems to be working fine).I don't have any Vista or 7 clients to test it with.I did hear about this with 2008 server and something about the security but I can't find the solution. The server is pingable and DOES access the XP and 2003 workstations fine.lforbes

Turns out it was Symantec Antivirus. How annoying when an antivirus causes more issues than a virus. http://www.eggheadcafe.com/software/aspnet/32800575/smb-shares-stop-respondin.aspxI have uninstalled it and installed Forefront which we have a site license for. So hopefully Microsoft's own products will work better with their OS.Cheers,Laralforbes
