This between the MOM Server in the US and an Domain Controller on the other side of a 256k VPN.

My question is, the default rules are in place, should I be customizing these rules to eliminate these alerts?

What do these alerts mean - I know what the 5 FSMO roles are but what is a Op Master Bind - just how long it took the remote DC to bind to the FSMO role owner?

I can easily modify the rule to increase the number of seconds in the threshold to fit my network but is that the right course of action?

I think maybe the reason this hasn't been addressed is that it falls into an area that is still not publicly documented. MOM contains a number of com objects that have various methods attached. From my examination of the timed scripts which run to produce these events and alerts you eventually can only reach a dead end because within the script if you are just given an object and method and there is no accompanying documentation to explain what that method is doing then unfortunately you do end up reaching a blank.

In SP1 the method for AD replication monitoring is altered, there will be a small application which is installed onto DC's to concentrate on the directory monitoring and report it to MOM.
