VMWare LabManager: Bad Handle 0x7B4, the handle is invalid
I’ve been doing a bit of work recently with VMWare LabManager. However, when accessing the machine consoles on a variety of operating systems (but always using Internet Explorer 8) we’d receive the error “Bad Handle 0x7B4, the handle is invalid”.
VMWare have a knowledgebase article about this issue that recommends you disable UAC. I don’t like this solution because I do believe UAC is a good thing and I think it’s important the developers develop and test with UAC enabled to catch UAC issues in their software early (the same reason I think developers should develop on x64).
After discussing the problem with our Internal Systems people they suggested trying to add the site to the Intranet zone, and low and behold, it worked! So I suggest you try this before the more drastic solution of disabling UAC.
