Request for Assistance with CPAU command in azure pipeline

Question

I am currently attempting to run a Windows Azure pipeline in which a specific job requires executing a command under a different user account. To accomplish this, I am using the CPAU (www.joeware.net) command.

However, I have encountered an issue when running the self-hosted agent as a service. If the user account I used to log in differs from the one specified in the CPAU command line, it results in an error (-1073741502). The problem does not occur if I input the same username and password as the admin accound that runs the self-hosted agent in the CPAU command.

It's important to note that everything works as expected when the scripts are launched either in the local session or with the self-hosted agent in interactive mode.

I would greatly appreciate any insights or suggestions you might have to address this issue when working with a self-hosted agent as a service.

          MKDIR C:\foo
          CALL C:\CPAU\cpau.exe -u DOMAIN\another.username -p "$(userPassword)" -ex "cmd.exe /c echo print bar file > C:\foo\bar.txt" -wait -lwp -outprocexit -cwd C:\
          IF %ERRORLEVEL% NEQ 0 (
            ECHO %ERRORLEVEL%
            EXIT /B 1
          )
          TYPE C:\foo\bar.txt

With this example, when the self-hosted agent runs in interactive mode the job is successful, but fails in service mode with error code: "-1073741502".
