How many RUS (EC/Domainxxx) to be said enough in Single Domain?   

Dear All,

I have 3 Domain Controller (also GC), let's call it A, B, C (A is the 1st
DC, 5 roles)
and I have 1 st Exchange server D, 2nd virtual cluster exchange server E.

However I checked in recipient update in ESM, we do only have:
"Recipient Update Service (Enterprise Configuration) - Domain - DC A -
Server D" (i)
"Recipient Update Service (Domainxxx)    - Domain - DC A - Server D" (ii)

Question: I was think to create more RUS:
Do I need to add RUS (EC)/Domainxx for DC B? and RUS (EC)/Domainxx for C?
and also repeating (i) & (ii) for Exchange Server E ?

I seems to be get lost here that what RUS to be said enough? I raised this
question that we
have the problem recently that an account was created (while Active
Directory User &
computer connecting to DC A) on Server E, the user account was stamped by
RUS and
update only DC A, DC B, but not DC C. For hours, it can not be updated on DC
C, I gave
it up by deleting that user account, re-created then RUS stamped correctly
user account and
updated on DC A, B, C ok.


Regards,
JH
