Hello, I am not sure this is right place for this message so you are
wellcome to point me in to the right place.
We have 2000 server based domain with 3 domain controllers. Everething
was working fine, until I tryed to add any domain user to local
adminstrators group in computers belonged to domain. The problem persists on
every computer and whith every user in domain I tryed.
For add user to local administrators group I log on to computer as local (or
domain) administrator and make few simple steps:
local users and groups -- groups, choosing administrators groups --
all tasks -- add to group -- press add, choosing from drop down menu our
domain and choosing some domai user. When I press OK the next message
appeared:
Processing of object <user name> failed with the following error:
The special domain either does not exist or could not be contacted.

If I try again there will be only local computer to choose from grayed out,
like no domain available. Once again it happens with every computer and with
every user I tryed and beside that there is not any problem in domain
(everything just working fine). If I use Network indentification wizard it
works well and I can add user to local computer and make him local
administrator.
The question is what is wrong with my domain and how may I fix it.
Thank you in advance.
Gennady.

Did you try just "looking it up" there? It is fairly common
to be unable (sometimes I have trouble) to type in group
names precisely.

But keep reading....

Sounds like it might be related to authentication or name resolution.
Authentication is usually name resolution anyway.

Let's check this (good idea in any case):

DNS is dynamic
If you have multiple subnets and legacy clients, add WINS server(s)
All Clients point their NIC DNS server properties (and WINS) to the
INTERNAL Dynamic DNS server (set) ONLY.
DCs are clients too, so their NICs are set this way
(If you need Internet resolution, then internal DNS forwards to
ISP or otherwise does the Internet resolution.)

If you change the above, restart NetLogon service on each DC.

Also, run DCDiag and capture the output to a file to search for
FAIL, WARN, ERROR.
