I need to run an isinteg on our single Exchange 2007 server since it periodically drops warnings in the event log which slightly concern me.

The server is running local continuous replication (LCR)

What I can't get my head around is how LCR will work when I run isinteg against the information store. Presumably isinteg doesn't create a transaction log so I'm not entirely sure how the LCR store is supposed to catch up to the live one. Does it just get dumped and a new one created?
