Disjoined Namespace after upgrade

8 months ago, I upgraded our first NT 4.0 PDC to Windows 2000 server.  The upgrade went fine and the other 2 NT 4.0 BDC's on our network cominucated fine with it.

I just placed a new Windows 2000 server on our network and was triing to add it to the domain as an additional (bdc) domain controller for an existing domain.  I kept getting error messages saying the domain I was triing to join was non-existant.  After a little research, I releatized that when I initially upgraded the first NT 4.0 machine (old PDC) there was an error that took place that caused a disjoined namespace.  My domain is local.company.com.  My server name is DC1.  If I look at Networt ID, my computer name is showing as DC1.company.com with a domain of local.company.com.  You see my dilema..

I found a Microsft article that explains how to fix the problem.  Here is the link: http://support.microsoft.com/default.aspx?scid=kb;en-us;257623.

They recommend running a script that will correct the FQDN of the server.  I am willing to try this just a little concerned about the repercussions.  Looking for advise from anyone that may have done this already.  Will I loose any profile information?  Does anyone see any other issues that may arise by running this script 8 months after I have been running with a 2000 server acting as the "PDC" for this domain??  Any advise or tips appreciated..

Thanks You
Chad

you can just change the registry keys listed after the script
i have run the script, and i have changed the registry keys many times for customers

this will be exactly what you need and there will be no repercussions
this is basically step 14 from this article

except they have given you the script if you want it

I ran the script and it solved the problem.  I was then able to migrate other Windows 2000 to active directory.  Thanks for the help!!!

No more sleepless nights!!  AT least for this week
