I have spent a week on this, looking at every offered solution here and elsewhere. I've tried them all. Nothing seems to work.
I have inherited a client with a 2000 Server running ISA, Active Directory, etc. My first task was to deal with some antivirus stuff, and at that time I realized that 2 machines were not running on the domain. I attempted to add them, and received an error:
"Your computer could not be joined to the domain because the following error has occurred: The network name cannot be found."
From all the research I have done, this appears to be a DNS issue. Well, I can resolve the server (from which the workstations get IPs successfully) by name. When I first try to add the machine to the domain, I get a message saying "An account for this computer has been found in the domain "XXXXX."" (Where X is the correctly identified domain)
There are certain places where the domain is listed as XXXXXX and some where it is listed as XXXXXX.local. I have tried adding the workstations using both. It seems to prefer XXXXXX to XXXXXX.local as it times out very quickly when using XXXXXX.local during the add process. However, when I check a machine already added to the domain, it says it is on the XXXXX.local domain!!!!
I have compared network settings on the 2 non-domain machines with the domain machines, and I see no differences. I have tried deleting the pre-existing computer accounts for these machines (they replaced older machines that I no longer have access to) and tried re-adding. I even tried re-creating the computer accounts on the domain, no joy. Tried renaming the computers and trying both of those. Nothing.
The best clue I have is in my attempt to view the WINS server from the server itself. WINS service is running, but I get the error "The network path was not found."
I am simply a poor tech who has been forced into the role of server admin. PLEASE HELP!!!!
