I have two Win2K domain controllers. The first one was upgraded from a Win NT 4 domain. The second was added to the domain later.
When I try to access the first server from any client or from the second server by using the machine name (i.e. \\firstserver) I get the error message “Login Failure: target name is incorrect”.
If I try to map drives by IP or by FQDN (\\firstserver.mycompany.org) I am successful.
I have no problem with accessing the second server from either the client or fromthe first server.
One thing that I noticed that was not done correctly: when we upgraded the first server we never changed the domain name connected to the NIC. So the machine name was firstserver.mycompany-ny.org. I followed the registry hackin Microsoft Article #: Q257623 but I still am unable to access the firstserver correctly.
This was the first server in the domain. I tried running DC Promo to demote the server to a standalone and fix the problem but I am unable to succesfully run DC Promo.
Thanks
