How to check the replication frequency in a domain with multiple DCs?

[Richard Sharpe]

Hi folks,

QA have found a problem where sometimes removing a Samba-based member
server with 'net ads leave' fails with ENOENT.

This is happening in a domain with two DCs and it looks like the
problem is related to the fact that sometimes it tries to do the
machine account delete on the DC that the join was not done on and the
info has not yet replicated.

Where can I check for the replication frequency etc in W2K08R2?
