File and Printer Sharing not working

[negg]

So I have installed a nLite copy of windows 2003 server and everything seems to work fine except File and Printer Sharing, the protocal is there under network connections however the 2003 computer cannot access any computers via \\computername or \\ipaddress and no computers can access the 2003 computer via \\computername or \\ipaddress. Remote desktop works fine and i can ping between the PC's, but no access to file shares.

Any help is greatly appreciated.

Thx.
