VMware KB: A Windows 2000 virtual machine created using P2V Assistant fails
Install VMware Converter (what version?) on the server itself (can I install VMware Converter without creating any problem to the existing applications?) an use it to convert the server?
You ca safely install Converter Standalone directly on physical source without affecting existing applications... when you install converter chose "Local Installation".
As destination type chose VMware Workstation if you do not have 4.x vCenter or ESX host ...
