NTFRS Error 13568 - File Replication Service disabled for more than a year

I am working on an environment with 2 Server 2003 domain controllers.  SRV1 has all of the FSMO roles. It is also the server that we make all of our AD modifications from.  I have just found that the File Replication Service on SRV1 has been disabled for over a year.  This of course has caused NTFRS errors in the logs for SRV2.  
I have enabled FRS on SRV1.  SYSVOL on SRV2 does not have a current copy of the SYSVOL share which is causing USERENV errors for clients when they try to update their GP.  The common fix for error 13568 tells me to enter an item in the registry on SRV1 that will tell SRV1 to delete itself from the replica set and pull new information.  My problem is that SRV1 is the server that has the current SYSVOL information, so I need to know how to get FRS working again without losing my existing information on SRV1.
I have made a system state backup.  I have considered running the registry edit and then restoring the System State back after it has pulled the replication info from SRV2, but I wanted to check out what you all though first.
