I am a realtively new systems administrator who has inherited a badly designed network. I had a couple of days off work and when I came back, my secondary server could no longer access my primary server. When I try to access a shared drive on the primary server from the secondary server I get the following message. "F: is not accessible. Logon failure: The target account name is incorrect." I get the same message on all the shared drives and also when trying to access the primary server directly through the Windows Network. I can ping both servers OK. Does anyone have any thoughts? Thanks in advance for your help.
