Fiddler and RDP/remote desktop

[Jacques Hemming]

I'm using Fiddler to inspect web traffic, and for an unrelated task I need to use remote desktop. Whenever Fiddler is open my remote desktop won't connect. Existing connections also die.

Is there a Fiddler setting I can change to prevent it acting as a proxy for RDP, or should I be looking at changing the remote desktop properties?

Generally speaking, RDP doesn't run over HTTP and thus it shouldn't ever be seen by Fiddler. Are you seeing CONNECT tunnels in Fiddler that point to your RDP server? (If so, could you send me a SAZ file?)

 

If for some reason your RDP traffic is getting tunneled over HTTPS, you can probably fix this by using Tools > Fiddler Options > HTTPS to either exempt your RDP server's hostname, or all non-Browser processes, from HTTPS decryption.

Hi Eric, thank you very much! This did the trick.
