Hallo, I just finished installing a WMS2012 server and evrythings works fine, at least for the domain administrator accounts.
After adding the teacher AD group to the local WmsOperators group on the WMS server, each teacher gets the following error message after strating the MP dashboard "A positional parameter cannot be found that accepts argument 'xxxxxx'.", whereby the xxxxx is the last name of the AD user account of the teacher. Sometimes it works fine after clicking away the error message for 3-4 times, but sometimes it completely crashes the dashboard.
The users log in as "FirstName LastName", so it is the LastName part that gets put into the error message.
Any ideas?
