XP computer suddenly blocked from workgroup
We have 5 PCs on a workgroup.
Everything was working fine, including network printing and visibility and mapping of shared resources. Every PC could see all the others in the workgroup. Suddenly 1 PC cannot see the workgroup - even itself! Get the standard message re check permissions etc. Other PCs IPs can be pinged, have rerun the network setup wizard, checked firewall settings. Changed the workgroup name on the problem PC - it still is not allowed to access its own shares. The users are not sophisticated and did not change any settings. Where should I be looking? What can cause this to happen? David K, melbourne.au

It could be 3rd party software issue. For troubleshooting try clean boot.

XP computer suddenly blocked from workgroup
Hi David,
I had nearly the same problem. It was due to nod32 antivirus/fw config. Although it was disabled, it seems incoming udp was blocked. The computer browsing network has sent requests, but udp answers from other computers were blocked. There was a checkbox in nod32 network config, and it works now. I didn't change anything to network config. Regards, Alain "David K" wrote in message ... We have 5 PCs on a workgroup.
