Hi Doug,
Thank you for posting up.
These are brand new servers and are very fast quad core with gobs of ram - everything else runs on them perfectly well including all the office applications, our main application of record a custom app written by myself and our helm application - no problems anywhere - even paymate has no problem.
We recently retired a server from the data center and threw it back into operation in a non critical role and installed a fresh copy of Win2K3 but without the R2 extensions and now that I say it - I have a gut feeling that the schema extensions that R2 brings might be the problem.
I will investigate and post up.
Cheers, JK
