Greetings all,

Have a fresh MS RDS deployment where my web access / client feeds just stopped working yesterday. Error I get is:

Exception Details: System.ComponentModel.Win32Exception: The operation completed successfully

Line 186: strUserIdentity,
Line 187: FeedXmlVersion.Win8,

Source File: c:\Windows\Web\RDWeb\Pages\en-US\Default.aspx Line: 185

My configuration is as follows:

2x Server 2019 VM's running RD Web Access and RD Connection Broker in high availability

Steps I've tried:

  1. Restarted IIS on both hosts
  2. Re-install Web Access on secondary server
  3. Switch web.config / IIS to Windows Authentication & restart IIS
  4. Switch web.config / IIS to Forms Authentication (default) & restart IIS
  5. Reboot secondary server
  6. Reboot primary server

Anyone seen this before and know what may cause it? I'm at a loss. Not certain the exact time it broke, but I was in the process of publishing applications yesterday. Not certain how/why publishing applications would break Web Access.

    So as I rolled back work I did yesterday the final thing I tried was removing a custom icon graphic for one of the applications. That did it. Apparently no 256x256 icons for RDS.
