I recall an older windows 2003 VM which was running service pack 2 being very slow under xen, and the solution was to upgrade to service pack 4 (from the xen mailing list, advised there was something windows did to make xen very in-efficient pre sp4). I don't recall if this applied to win2000, but I will probably upgrade the win2k DC to windows 2003 service pack 4 over the coming weekend (depending on approval/etc). AFAIK, this should be a fairly painless upgrade, and is definitely something I want to get done anyway. I'd still like to focus on running some tests to ensure the system is working properly, and/or find the issues in the other parts and resolve them Thank you to everyone who has offered any suggestions or advice so far.
