#1. We should leave the /NOPAE switch in the BOOT.INI files since most customers do not put more than 4GB of RAM in their boxes, and they don't honestly care about DEP on dedicated & locked down servers. I.E. They do not appear to get any benefit from adding it on 4GB machines other than DEP support.
#2. Understood - I think the fact that you all are only running the mod on one server speaks volumes. I would be interested to know if the virtual memory issues you all saw had anything to do with the fact that the server was on a cluster (assuming it was since ITG clusters every production mail server from what I know).
Thanks for the continued advice and support Paul!
