done that. been working on this for months. no firewall. Ping replies are not disabled.
thinking that may be more of a stack overflow. Been a part of more than one workgroup over the years.
As an aside, I downloaded and installed netbeui on the problem machine and two others. It's been a long time for netbeui and me, and I'd forgotten about it, but the two other machines could instantly see and access the problem pc.
so I think it's a tcpip issue. and I'd really appreciate help solving it.
In direct response to you Cyberat_88, is there a way, to quickly unsecure a pc, like... to revert to defaults?
