Server 2008 R2 RDS Farm of 5 servers plus 1 gateway. Last week we had an issue were our servers failed over to a secondary cluster. After this fail over the RDS gateway no longer redirects logins to the farm. I moved the servers back to the original cluster and still no redirects. When working RDSGW will forward\redirect logins and load balance according to which server has the least amount of resources used. Now when using the RDSGW it tries to log into itself and since normal users are not allowed access to RDSGW logins fail.
