I have a client with 1 PC that will not log on. As you all know if you do not log on then network resources are not available. If I just log off and then log on all is well. It just won't log on when you start or restart. I have unistalled all services and clients and TCP. I have removed all PWL files. This is a Win98 SE box, on a all Windows Peer to peer network. Files are located on a snap server, so access is important.
start run regedit
LMLogon (binary value) set to 00 00 00 00
PolicyHandler (string value) set to "Grouppol.dll,ProcessPolicies
PrimaryProvider (string value) set to "Microsoft Network"
username (string value) set to (there name)
Let me know if that worked.
