Lost AD Global Catalog Server

[Jordy]

I've lost my global Catalog Server and cannto restore
it...I have 3 other domain controllers, but I cannot seem
to access the sites and services pluggin to promote one of
the other DC's without the GC being up? Any specific tips
options?

install Windows Server 2003 admin tools on your XP workstation and in
command prompt issue

dsmod server "<serverDN>" -isgc yes

where serverDN = DN of the server in your configuration/sites container like
CN=yourservername,CN=servers,cn=Default-First-Site-Name,CN=Sites,CN=configur
ation,dc=domain,dc=...

if your server is in different site, then substitute Default.First.Site-Name
with someting else.

Unfortunatly I am in the same spot with this command...It
still tries to authenticate.

D:\>dsmod server CN=POSTMAN,CN=Servers,CN=Default-First-
Site-Name -isgc yes
dsmod failed:The specified domain either does not exist or
could not be contacted.

Thanks for the tip on the 2K3 tools.

How did you lose your GC ? If the DC that was GC is not around anymore, then
use http://support.microsoft.com/default.aspx?scid=kb;EN-US;Q216498 to
remove any references from it. Can you logon on another DC ? What error do
you get if you open Sites and services snapin.

dcdiag gives the following errors:

Testing server: Default-First-Site-Name\POSTMAN
Skipping all tests, because server POSTMAN is
not responding to directory service requests

Testing server: Default-First-Site-Name\POSTMAN
Starting test: Connectivity
POSTMAN's server GUID DNS name could not be
resolved to an
IP address. Check the DNS server, DHCP, server
name, etc
Although the Guid DNS name
(73d21e9f-f4e7-4f55-a54e-
eb09925482d9._msdcs.SceptreABS.com) couldn't
be resolved, the server name (postman.sceptreabs)
resolved to the IP
address (192.168.X.XX) and was pingable. Check
that the IP address is
registered correctly with the DNS server.
......................... POSTMAN failed test
Connectivity

This is somewhat frustrating!
