ERROR

"You were disconnected from the Windows-based computer because of problems during the licensing protocol"

I have scoured the Internet and have read it can be fixed...but no one has given me a working fix. I have tried many fixes but still no luck =(.

Anyone know a FUNCTIONING fix for 10.7 and or 10.8

I am using Remote Desktop Connection Client for Mac | Office For Mac (the latest version) to connect to Windows Server 2008 R2 Standard. Running RDS with a 5 User CAL. No Active Directory just basic accounts as the local IT team hasn't a clue how to use AD and I am a thousand miles away.
