Event ID 5719: No Windows NT or Windows 2000 Domain Controller is available for domain <domain>.

Okay, I successfully shot myself in the foot a few days ago. Managed to lock
myself out of a Win2K Pro workstation by messing around with a Group
Security Policy on the Win2K DC. Panic set it and I eventually fell upon
this KB article:


Without thinking [...could probably stop right there...] about stashing a
backup copy of the system32\config\security file I stomped on it with the
repair\security file and went on to attempt cleaning house. I deleted the
newly-created GSP from the DC, removed the workstation from AD, and changed
the workstation to rejoin the domain.

Checking the workstation's Event Log from the DC (fresh workstation boot and
without logging onto the workstation) I get the following error:

Event Type: Error
Event Source: NETLOGON
Event Category: None
Event ID: 5719
User: N/A
Computer: MYWIN2KPRO
No Windows NT or Windows 2000 Domain Controller is available for domain
MYNET. The following error occurred:
There are currently no logon servers available to service the logon request.
0000: 5e 00 00 c0

Citrix and RAS are not part of the picture. (Yeah, I've run across several
of those KBs.) NetBT buffers is not the problem either. (Yeah, I've hit
several of those, too.)

At shutdown time for the workstation, I get a DCOM error:

Event Type: Error
Event Source: DCOM
Event Category: None
Event ID: 10010
User: MYNET\Bonehead
Computer: MYWIN2KPRO
The server {563B0D4F-3080-4B80-B47A-7CA258999376} did not register with DCOM
within the required timeout.

Searching through the workstation's Registry,
563B0D4F-3080-4B80-B47A-7CA258999376 = AcctMgr.FormHandler CLSID.

I'm pretty much convinced I've successfully hosed the security settings on
the workstation. (Gee, ya think?) Short of nuking the village and starting
over, or considering a career in basket weaving and door-to-door sales, I'd
appreciate some constructive assistance in correcting this.

[Bonus follow-up question, with double the trivia points, regarding Event ID
565 appearing in the DC's logs for whoever successfully solves today's
trivia question.]

Help? Please? Anybody?
