Running with the everyone user at all is wrong. I run hundreds of 2K servers and that is the number one rule besides patching of course. LK, please don't use the "blame microsoft" thing for this problem. I have run this version on IIS without a single issue.
If you are being hosted then getting on a *nix server is your best bet. If this is your own server then make sure that the disk subsystem is fast enough and running NTFS.
