HelloI have a problem with DPM 2007 sp1. First, I have 3 windows server 2008 running Exchange 2007 sp1 with rollup 5in Mailbox Role with SCC,.In addition there are 2 instances VMB1 and VMB2 on the SCC which contain each 25 storage group and 25 databases (1 per storage group).I have 2 active node and 1 passive. DPM sp1 is installed on windows server 2003, with the KB 959605. The agents have the same update (2.0.8793.0). The problem is that I have succeeded to protect the first 25 storage group on VMB1 (with ese.dll, eseutil.exe).But I can't see the other 25, because they don't appear (only the volumes are present) under VMB2. Why the other storage group on VMB2are not visible in DPM ?Thank You Regards,Jeremy
