Question : SBS2003 Domain Controller Server - all users working offline and can't print to shared printers

As of last night after a reboot my domain users log in as normal and are showing that they are working offline.   Exchange is fine and shows connected.  They can access all shared drives (but I have them mapped to IP Addresses).  All their printers that are shares on the server show "Unable to Connect"

in users printers/faxes it has shared as Printername on <ServerName> - Unable to Connect

now if I delete and add again (which all printers are found doing search AD list) -
it shows up as Printername on <servername>.<domainname>.local - Access Denied, Unable to Connect   - but they can open printer and print to it.

Also if i open a my computer and put in \\<Servername> I get different folders than \\<Servername>.<Domainname>.local

I dont know of any changes of setting on the SBS2003 server.  Anyone know what could do this?  And even more important on how to fix it.

They can ping the <servername> and get the correct IP Address.  

Answer : SBS2003 Domain Controller Server - all users working offline and can't print to shared printers

ok here is what the guy said he did:

 moved the problem computers from the old Active Directory OU "computers" to the other OU "SBSCOMPUTERS". I modified group policy to allow turning off "Offline Files" on the clients.

I disabled WINS on the server and modified the DHCP scope options to force NETBIOS off and force the DNS suffix to "versalifteast.local". This forces all name resolution to use DNS instead of NETBIOS.
