Exchange user does not appear in GAL (not exchange mailbox update on one of domain controller GC)   

Dear All,

I have 3 Domain Controller A (1st DC, operation master 5 roles); B, C.
(A, C are GCs). A, C are on SP4, B is on SP3. Will update SP4 on B domain
controller be
helpful to resolve the problem?

It just happened today that while on Exchange  Server to create new account
(the Active
Directory appearing to connect to C), the user account is created and
updated across other
A, C, mailbox is created.

However the email address is not updated for new user specially email
address field is empty while using Active Directory User & Computer to
connect to C. I checked on A, B the email address of this new user by
connecting Active Directory User & Computer to those DC, and
confirmed that the email address is updated correctly.

On my Outlook, I checked the Global Address List there is no new created
user listing (the
exchange server probably using GC on C so the GAL does not have the new user
listing.)

But if I wait for a while (until Exchange server connecting to A), I can see
the GAL has
the new created user in listing.

It has been for 5 hours already sine I created the new user, but it is not
updated on C domain
controller.

I forced the replication, sync, clicked update now for RUS in ESM etc..but
it does not help. It
just happens today, I do not notice whether the replication of active
directory might have the
problem before, but we do not have this problem at all for 4  years running
Windows 2000 AD, Exchange.

Any one idea? please help
