Hi,
I just got a brand new PC running Vista. I plugged it into the network. It can see all the other PCs on the network, and access their shared folders. It can also access the Internet.

However, no other PC can access anything on the new Vista PC. Sometimes, not always, an icon for the Vista PC is displayed in Windows Explorer-Networks-Workgroup on the other computers. However, when 2xclicking on the icon, an error message comes up that this computer cannot be accessed. They all use the same workgroup. I have verified that and that the icon pops up there sometimes under the workgroup seems to confirm it. Also, the IP addresses all PCs get when they are started look good.

The other computers run both XP-pro and Win2000 pro.

Any hints, ideas much appreciated.
Thanks,
Matt
