Exchange 2003 Enterprise configured in a two node active passive cluster.
4GBs of RAM installed and using 3GB switch.
Noticed that lsass.exe is using 2.2GBs. Recrcmon.exe using 1.3GB. Store using 672MB.
Server is a bit sluggish. When remoting to it - receive out of resource errors. Cannot run System Manager for same reason.
Do not think server is infected with sasser.
