Lately, I came across a strange issue after setting up a new Windows Remote Desktop Services farm running Windows Server 2008 R2 Servers. When accessing a RD Session Host through RDP on the hosts’ NetBIOS, FQDN or IP address as Administrator, I was redirected to an another RD Session Host. Logically, because the RD Connection Broker has load balanced the request. Anyway, I still wasn’t able to login as Administrator on the RD Session host, even when using the /console switch. After some research I found out that this switch was replaced with the /admin switch. When I used the /admin switch I was able to connect to the RD Session Host without the redirection from RD Connection Broker.
