The remote Computer 'DES0500' requires Network Level Authentication, which is not ena

Hi,

OS: Windows 10 Enterprise
ASG-RemoteDesktop 2015: Version 8.0.5034.1

After Update from 1607 to 1703 Enterprise Version i get the following Warning

Warning
The remote Computer 'DES0500' requires Network Level Authentication, which is not enabled in the rdp Connection properties.

If i connect directly with mstsc, the connection is working fine

By the way, in 1607 there was no Problem...

Any ideas?

Thanks in Advance  

Stefan
