Check all IP settings against machine. What are you using for DNS and WINS?Enable NetBIOS over TCP/IP on one or more computers in the workgroup. To do that, go to properties of Local Area Connection>properties of Internet Protocol (TCP/IP)>General> Advanced>WINS, check Enable NetBIOS over TCP/IP (If you have a DHCP-assigned IP address, select Use NetBIOS setting from the DHCP server ). 2) Make sure the Computer Browser service is started.
