The Exchange Servers group got deleted a few days ago and now we get the following error: The Microsoft Exchange Replication Service attempted to start the RPC server but failed because an error occurred when attempting to read the Exchange Servers Universal Security Group SID from the Active Directory. Error message: Failed to find Exchange Servers group in Active Directory. When I have run into this problem withExch 2003 I would just re-run ADPREP, but when I try to do this in 2007 I get an error. Any ideas on how to recreate this group and add the right permissions? Thanks

Hi, You need to run setup /PrepareAD & "setup /PrepareDomain" to recreate the groups in Exchange 2007. How to Prepare Active Directory and Domains http://technet.microsoft.com/en-us/library/bb125224(EXCHG.80).aspx
