I have been fighting this idiocy in programming for weeks now. Currently we have an RDS 2012 farm with (2) RDG server, (1) RDCB server and (6) RDSH servers.
Randomly when users login they are blocked with the following message:
The user "DOMAIN\username", on client computer "172.31.0.51", met RD resource authorization policy (RD RAP) requirementsbut the network resource "172.31.6.1" did not meet the requirements, so the connection was not authorized. Try connection to another network resource or possibly lower RD Gateway security by modifying the RD RAP requirements for the connection to be authorized.
I am trying to figure out how my network resource (RDSH servers) randomly meet, then don't meet the requirements. Also why does the RDCB server randomly change from using the FQDN, NetBIOS and IP address of my RDSH servers???
