[Resolved] Did not receive port from client process

PowerShell Universal
1

I am trying to set up a simple demo for IT meeting later today so I can get some budget for Automation, but I am stuck at the very basic step - trying to run a simple whoami script using PSCredential that I saved.
Could this be some kind of permission issue with IIS again?

edit: just to clarify, jobs run using default user, but not when using PSCredential from vault

PSU 1.2.8
IIS 10.0
Runas InProcess as domain user standard account.

This is all I get from error log, nothing interesting in Event log:

Any ideas?

I get same result as above when running as Network Service on IIS

Similar problem when running manually on Windows 10 in my user context (non admin domain user), just different error this time. Clean install of 1.2.8 as well

hey @raymix,

afaik, if you wanna be able to do run As you have to run the dashboard as local System:

IIS Limitations with Universal Automation

  • App Service configured as Local System - Scripts will execute as the System Account by default and a Run as Accounts CAN be specified when executing a Script in Universal Automation
  • App Service configured as a Service Account - Scripts can ONLY be executed with the Service Account and a Run as Account CANNOT be specified when executing scripts.

check this for IIS hosting.

Thanks, @Speegel
Not sure how I missed that big bold warning… but to be fair, this is not just an IIS limitation, I get the same problem when manually running .exe in context of standard domain user (me)

So now I need to solve dilemma of:

  1. Running scripts as administrator, can use RUNAS
  2. Not running scripts as admin, can’t use RUNAS, but could potentially use API calls with Passwordstate.

I’ll mark this as resolved, thanks again :+1:
