Hey All,
Running into a curious issue that I've been trying to fix on and off, related specifically to using "Remote Resources" from the RDP App version 8.0.9 on OSX only.
When I type in the (proper) URL for my RDWeb Server, it hangs and never displays any remote resources. What is more alarming however, is the IIS traffic server side shows it continually retrying and failing without ever stopping. The only way to get it to"stop" is to go back in and blank out the Remote Resources fields, and press refresh. I've been able to eat up a significant amount of CPU on my RDWeb servers by just getting 5-10 Mac's trying to connect at the same time, and let it run for 5-10 minutes, it just never stops retrying.
The server side logs look like this:

...and on and on, repeating in an endless loop until I manually blank the details within "Remote Resources" on the Mac.
My first thought was to chase down the 401.2 error, which leads me to believe the Client and Server did not support a common authentication scheme? We do currenlty do some basic server hardening via GPO - disabling RC4 and SSLv2, as this server is intended to be publically available when we go live. However, reverting this stuff back to "stock", and rebooting, has not alleviated the issue, or change the IIS log output. My research on the various 401.1 errors hasn't gotten me anywhere either, unfortunately.
The interesting thing is, using Windows 7, 8, 8.1 is fine. Using Android's RDP app, as well as IOS RDP App, I can use the "Remote Resources" function just fine. We are using 100% Public trusted CA certs, and everything "else" seems to work with the exception of "Remote Resources" on OSX specifically.
On OSX, I can also use Safari, or Firefox and load the Remote Desktop Web Access page, and launch an app successfully (Minus the still existing RD Gateway issue, which requires the .RDP file be manually edited first to work through an RD Gateway on OSX, it still ignores these settings as of 8.0.9). Additionally, within Safari or Firefox, I can visit the "/feed/webfeed.aspx" url and login, to where it will download the RSS feed as a file, so it appears to "function" at least through the browser to some extent. (it is my understanding that all the Remote Resources portion should be doing is downloading the RSS feed and populating it within the RDS app for convenience?)
Has anyone seen this before? Surely I can't be the only one....? Thanks in advance for any help/suggestions, I can provide additional details or clarification if needed.
