We have 4 servers in a windows domain which have all been running fine but we have just lost connectivity between one of them and the others. clients can log on to the network and recieve emails (which are running on the server that has lost connection :Mail (on win2k server) but cannot access mapped drives off of any other servers (File 1, Web 1 and hayfield).
when trying to browse from Mail to file one or web 1 through the network we get the message \\File 1 not accessible logon failure the target account name is incorrect.
we can ping mail from all servers/pc's and can access it through remote desktop connection..
we have run dc diag test :
