hey dgedes
thank you!
well than, but now i know what i have to do.
so i think for some project's i can use the RDSH in a workgroup, and i think it is supported.
the thing is, i thought i can outsource all my servers to azure, but now with a server for the active directory and one for the rds it is more expensive :(
or do you know can i use the azure active directory service for this szenario? http://www.windowsazure.com/en-us/home/features/identity/
thank you for your fast answer!
