Dispatch your Windows people to work on the fundamental problems with that W2003 system, which has probably been much neglected and needs a good defragmentation, and a good look at any virus scanning software it's running, among other standard tuning measures. The effect that it's having on communal TSM backups are a symptom of its malaise. Tivoli CDP may be a better backup approach for that system, which should be evaluated.
