At the risk of beating a dead horse on this topic, I recommend anyone currently testing VMServer 2 Beta on a Win2K3 Host to ditch the Web UI manager, in favor of the Virtual Infrastructure Client (v 2.5). After experiencing almost 48 hours of inconsistent crashing of my converted Win2K3 VM's, I disabled the Tomcat JSP Server on my host (listed as VMware Virtual Infrastructure Web Access under Services MMC.)

After completing this, and downloading /unraring the 32bit VIM 2.5 client installer from http://download3.vmware.com/software/vmserver/VMware-server-e.x.p-63231.i386.tar.gz, I am able to successfully connect to my VM's on my Server 2.0Beta1 Host on port 8333.

It has now be almost 72 hours with none of my VM's crashing, as well as recovering almost 300Megs of RAM, since disabling the VMWare Web Access service
