Exchange 2007 SP1 Fails during install of Organization Preparation.

I have a Windows 2008 Server and trying to install a new copy of Exchange 2007 Sp1 on it and i when i try to install it i get this error:

Entry DN: CN=ms-Exch-Access-Control-Map,CN=Schema,CN=Configuration,DC=internal,DC=globalconstruction,DC=com
Add error on entry starting on line 1: Busy
The server side error is: 0x21a2 The FSMO role ownership could not be verified because its directory partition has not replicated successfully with atleast one replication partner.
The extended server error is:

An error has occurred in the program

You must have a partner that isn't replicating.
Check the event logs, run DCDIAG and see if anything comes up.
If you have successful replication reboot the server and try it again.  DCDIAG will probably should you something though.
Also this could very well be someone removed a domain controller without actually demoting it in the past.
Please open Active Directory Sites and Services - and check how many DC do you have - ensure that you are able to complete replication for schema between those servers.

Replmon is one tool that i use alot for fighting replication partition wise - in your case schema partition needs to be fought with.
