Based on problems others have posted with rollup 5 for exchange 07 i might try uninstalling that and perhaps re-install rollup 4. No other issues with the machine right? Ruled out a bad stick of RAM or something?

Correct, there are no other problems. I'll try uninstalling rollup 5, and go back to 4.Thanks
