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 :
C:\Documents and Settings\Administrator>dcdiag

Performing initial setup:
Done gathering initial info.
Doing initial required tests
Testing server: phoenixent\MAIL
Starting test: Connectivity
b7add9d3-f4cf-4755-b6a9-a77596aca3e8._msdcs.phoenixent.local's server G
UID DNS name could not be resolved to an
IP address. Check the DNS server, DHCP, server name, etc
Although the Guid DNS name
(b7add9d3-f4cf-4755-b6a9-a77596aca3e8._msdcs.phoenixent.local)
couldn't be resolved, the server name (mail.phoenixent.local) resolved
to the IP address (192.168.0.57) and was pingable. Check that the IP
address is registered correctly with the DNS server.
