I have an Exchange 2000 active/passive cluster. Both nodes have SP3 for Exchange
and Trend Micro's ScanMail 6.1. I then installed Norton AntiVirus Corporate
Edition (NAVCE) 7.5 "unmanaged" client on both nodes. After that, I configured
both nodes to exclude scanning of the Exchange's, IIS', and ScanMail's system
files including the "Drive M" of Exchange. After I perform a manual failover,
some of the Exchange cluster resources on the active node are stopping, offline,
or have failed. This will also be the result if I switch it back to the
previous node. To resolve this, I have to uninstall both NAVCE 7.5 and ScanMail
6.1, and then reinstall again ScanMail 6.1. How can both ScanMail 6.1 and
NAVCE 7.5 work properly in an Exchange cluster environment? I need NAVCE
7.5 for file-based virus scanning.
