I am pretty sure that this has been dealt with before, so hope somebody will remember the solution and help out.
I have two computers (Dells) fairly new, both running xp-pro with sp2 & all patches, that have the problem. They will NOT network consistently, though both can sometimes see the workgroup, and sometimes one or both can see the other computer. Rarely, access across the network happens, but always on the next reboot it is gone again.
The error message shown above always appears when things go wrong. [sorry, I can't get my screenshot into this post. Anyway, it's "<computer name> is not accessible. You might not have permission to use this network resource. Contact your system adminstrator " blah blah & so forth...
Dell tech support gave up, back when these were brand new computers. Naturally they saw it as a Windows problem, and maybe it is...I really don't know.
