Xen App server - MMC failed to create empty document

When trying to launch any application that uses MMC, an error appeared Microsoft Management Console - failed to create empty document.

Solution:

I checked the knowledgebase article on Microsoft website that talks about checking for the Temp folder location and disk space on the hard-drive. My setttings appeared to be fine, the Temp location was at c:\documents and settings\%username%\local settings\temp

It seemed that the profile for the user logging in was corrupt, I was able to resolve the issue by deleting the user's roaming profile.
