Can't authenticated with the DC on branch

[Chai]

Hi there,

I got 2 sites - 1 DC at each sites, link with Internet.

I configure the AD replication and is working cause the
information is replicated to each other.

But when I try to join PC to domain at the branch (second
DC), it prompt out error message say that the domain
cannot be found - maybe cause by DNS lookup problems. So I
follow the link to microsoft web site and read all the
related topic. Then I check my DNS, AD configuration and
no problems with it.

The problems still the same - it seem like the DC on
Branch cannot identify it self as DC for my domain. Why?
The AD Replication is working but why the DC cannot
operate?

I even try to move the joined domain client PC from HQ to
branch but when I try to log on to domain - it fail.

I also configure the firewall between the site to allow
all IP traffic between the 2 DC.

Any ideas?

Thanks.

Hi,

I do already - I follow what microsoft web site say - 2
sites also DC, GC, DNS Server and record correct!!

Just that the DC in branch can't verify it's self as DC -
cause it can't locate the domain!!

Any ideas?

Thanks
