One of the VM templates stored in a library had a few properties modified (Numlock, RAM, processor count) and after saving those changes, there are several tabs missing from the properties window. I could not reproduce this on other VM templates. Clones of this template also have the tabs missing.
The missing tabs are OS Configuration, Application Configuration and SQL Server Configuration.
TFS 2012 lab management will not allow me to create an environment using this template, stating 'Domain User Name' is an not a valid property.
How do I get the missing tabs back?
