Server Error in '/RDWeb/Pages' Application.

Question

Hi all
We have a remote desktop services environment where users access most apps internally via our RDWeb gateway
Just today, we started to get a weird error which has never happened before
Also nothing has changed on the server since last week
Restarting the server and services dont fix the issue

When users try to access the main RDWeb site, they are thrown below error

When I turn on debugging for the Default.aspx file, I get the below error

Server Error in '/RDWeb/Pages' Application.

The operation completed successfully

HI TKujala,

Thank you for your message. I couldn't open the link you post. Could you please resend the link?

We have the exactly same issue.

Have you ever solved this?

Answer 4

One of your published Apps crashes the IIS instance. The newly published app Icon size is to big. Try to unpublish it and the issue should be resolved.

Quit simple solution - but very difficult to find (took us 8 hours).
