The user has a 3-user network, all on Win7 Pro, One PC is where they share their files, with a computer name of "Server".  Up until today, the two workstations were mapped to the Server PC using this command:

Net Use F: \\server\c  

This has worked fine for years.  But today they can no longer connect.  If I delete the F: drive mapping, and once again do Net Use F: \\Server\c I get this error:

System error 6 has occurred
The handle is invalid

And if I browse to Network, I can see the PC named Server, but if I double click it I get this error:

Windows cannot access SERVER
Check the spelling....etc....
Details: Error code 0x80070033
The network path was not found

Other details:

1) They use Norton security.  I have tried turning off the firewall and antivirus on a workstation and on the server to no avail.

2) I can still do the normal Net Use mapping on the "Server" computer--but not on the other two PCs.

3) I went to do a system restore on the Server PC, but to my surprise Windows said was disabled--so no help there.

Any ideas?  TIA
