I've recently deployed a RDS environment, with a fairly simple setup:
DMZ: RD Gateway / Connection Broker / RD WebAccess
RDS Server: Session Host.
I have also published Remote Apps, and all is well there, at least on Windows 7, and Windows 8.
The problem is in two places however:
Windows XP: I can't for the life of me get Remote Apps to work, or even a normal RD Gateway connection to work. With that one, I invariably get the message that the RD Gateway server is temporarily unavailable.
In my research, it sounds like it may be possible that Windows XP SP3 may simply not support RemoteApp. However, it should support at least a normal RDP connection.
I have turned off NLA on both the collection, as well as the RD gateway to support legacy clients.
Any thoughts on that?
The second problem is Macs. From all my reading, it seems like the Macs should be able to launch remote apps from the Resources, as well as connect to an remote session via the RD Gateway with no issues. However, every time I try to connect, I get the following error:
"The gateway failed to connect with the message: 503 RPC Error: 6ba"
I'm not sure why I'm getting that, given that all my other clients work just fine, even when connecting to a published RemoteApp.
I could not find anything googling this, and most issues that I found that are remotely close are related to SBS servers. I'm running Standalone Windows 2012 servers. Any thoughts?
