You can use this PowerShell to clean up the DCOM permissions issue.

The application developer will be your best resource to debug the application issue.

Answer 2

{F72671A9-012C-4725-9D2F-2A4D32D65169} is registered on my Win10 Home laptop as CDPComAccountProvider. I doubt that the DCOM error has anything to do with your application hang.

Is the app written in DotNet or C++ or what? Do you have the required run time components installed on the 2016 server? You really need to get the 3rd party developers involved and ask them if their code has been tested on 2016. Ask them if their code has any logging/diagnostic functionality where you can enable a trace, recreate the error, and then determine what API calls were made.

Troubleshooting a hang is going to require some low level diagnostics. The best tools that I have found are Process Monitor, Process Explorer and DebugDiag.

Does the app always hang at the same spot? That is, does the user click on a certain button and then it hangs? I would start by tracing the app when a user recreates the hang with Process Monitor.

Look at the last activity that the program does. Is it reading a database or something? Ask the developers if they have any insight as to what the program is doing and why it might hang at this point.

Is the app using cpu when it hangs or is it just "stuck"? Use Process Explorer and examine the threads to see if you can isolate the function hanging. Again you will need to ask the developers about this.

The last resort is to use prodexp to create a dump and then use DebugDiag to analyze the crash/hang.
