I have Exchange 2003 installed on Win2003 Server, which is member server in
Win2000 domain with 3 DC, each of them is GC.
The problem has started just today. I've created new user account and it
does not come up in Outlook's Global Address List.
However, in Exchange System Manager, in Default Global Address List
Properties I can see that user account in Preview.
With that extra information you might do well to
(cross)post to the Exchange and Outlook lists where
they are more likely to help you.
You should also identify the client OS, and the Outlook
version. For instance, the Win9x machines don't include
the ability to make LDAP calls by default (which may or
may not be related, see also DSClient update for NT/9x.)
Were it me, I would immediately check that the client
machine is AUTHENTICATING with the Domain
correctly, and has the correct DNS settings.
As an internal client it must use ONLY the internal
DNS server address (set), usually the one's within
the domain. (i.e., NOT mix in Internet/ISP DNS
server addresses.)
