Additional Domain Controller

[Jardyus]

Hi. I am currently running a small domain with 1 DC. In order to implement
better reliability, I am trying to add an additional DC to take over in the
event that the first one fails. I installed Windows 2000 Advanced Server on
DC2 and ran dcpromo. It has prmoted the server to a DC, however when DC1 is
shut down, users cannot login to the domain - the error returned is "The
domain DOMAIN is not available". I am not sure why this is happening? Do I
need to create a secondary DNS server manually? Do I need to seize a FSMO
role? I cannot seem to figure out what I have done wrong. Any help would be
appreciated. Thank you.

You need DNS on this second DC and then make both DNS zone AD Integrated.
Point all clients to these DC's for DNS, one for primary the other for
secondary. This should help.

I have done that, and I have updated the DNS on the client machines by
logging in locally. Whenever the first DC is down, I still get the error
message that the domain is not available. However, using nslookup, I have
queried the srv records and found that both servers are configured to act as
DCs for the domain. So why are the clients only able to connect to one of
them?

Run netdiag /fix then run netdiag /test:dns /v on both DCs. Post errors from
the test:dns

Hi Jardyus & Kevin,

I am facing the same problem as you had already faced. How you resolved this
issue. Pls help me in this regard.

ADC's for different doamins are working fine, except this one, which I need
more.

Problem is just a carbon copy of yours problem.

Thanks

What exactly is the problem?
You have posted a reply to a post that is older than the thirty day limit
when using NNTP in a News reader.

Some suggestions I can make without having more information is to run
netdiag /fix and restart the netlogon service on all DCs. Install DNS on at
least two DCs and use AD integrated zones, make sure the DCs and all clients
only use the internal DNS that supports the AD domain. This could also be a
Global Catalog problem, although only one Global Catalog is required in a
Forest, I would suggest having two GC servers so one is always available.
Posting an ipconfig /all from the DCs and a client will also help us
diagnose your problem.
