Logon Failure: The target account name is incorrect.
Posted on 2013-01-22
In an SBS 2008 environment, when any workstation (including the server) tries to access a shared folder on a specific Windows 7 box:
- using UNC path (eg. \\JACK-WIN7), the error "Logon Failure: The target account name is incorrect" occurs.
- using FQDN (eg. \\JACK-WIN7.mydomain.local), I can successfully access the shares.
I've read numerous articles and most lead to DNS issues. I tried removing the DNS A record related to JACK-WIN7 using the DNS Manager on the server and then ipconfig /flushdns and ipconfig /registerdns on the offending Win7 box.
One clue is, when I:
- ping -a JACK-WIN7 it pings the ip address of a different computer (which has a different computer name)
- ping -a JACK-WIN7.mydomain.local it pings the correct ip address.
