Describe the bug
In my lab environmen i'm having fun with this tool as my daily work involves alot of SCCM.
when i try to get the client-push credentials using the sharpsccm invoke client-push i get the following error
[!] An unhandled exception of type System.Reflection.TargetInvocationException occurred: Exception has been thrown by the target of an invocation.
I use a Kali Linux to run the responder.py, and using this command for sharpsccm
SharpSCCM_merged.exe invoke client-push -t 192.168.30.121

To Reproduce
Steps to reproduce the behavior:

  1. Run sharpsccm.exe invoke client-push -t x.x.x.x

Expected behavior
No unhandled exceptions

** SharpSCCM version**
Latest github code

** Management point server specs (please complete the following information):**

  • OS: Windows Server 2022
  • ConfigMgr Version Technical Preview 2305

Client specs (please complete the following information):

  • OS: Windows 10 and Windows 11
  • ConfigMgr Version 5.00.9102.1008

Additional context
Any advise is greatly appreciated

Thanks for this report and the one you opened last week! I'll take a look now and see if I can reproduce the issue.

@Mayyhem sounds great... Maybe I'm just doing it wrong :) And btw great session you had with Panu and Sergey at MMS MOA :)

That's awesome to hear!! Thanks for coming :) I had a blast and definitely plan on submitting more talks next time around.

I'm unable to reproduce on version 2303 using the latest code in main. Could you please run again with the --debug option and paste the results here? That should produce a bit more info about the exception.

Nice!... will definitely prioritize those sessions at next MMS MOA.

Maybe I'll need to go through my lab environment again to verify the prereqs for this to work.

Here's the output with --debug
`C:\Users\xxxxxx\Desktop>SharpSCCM_merged.exe invoke client-push -t 192.168.30.121 --debug

I'm going to have to install technical preview and see if the issue occurs, which might take me a bit. I did a side by side comparison and it looks like the only significant difference between our outputs is this:

My output contains ConfigMgrRegistrationReply will be signed: False, while yours doesn't, then it fails. Not sure exactly why. You have HTTP enabled?

Just verified that i have the same Communication Security settings i my LAB

I see in the Configuration Manager docs that from 2211 these fixes are included
https://learn.microsoft.com/en-us/mem/configmgr/hotfix/2207/15152495 which include https://learn.microsoft.com/en-us/mem/configmgr/hotfix/2207/15599094 and https://learn.microsoft.com/en-us/mem/configmgr/hotfix/2207/15498768

Could that be the reason why i cant get it to work on latest preview?

I don't think so, since SharpSCCM fails before the stage where NTLM comes into play and it's working in my lab. I'm going to get Tech Preview spun up and try and live debug to figure this out.

Cool.. I'm spinning up a 2203 site and do some testing there.

@Mayyhem
Well... turns out, it's working just fine with CM 2203 release, so MS must have done something in later builds :)

Interesting! Thank you for testing that. And assuming that change was on purpose, good job Microsoft! 😄

I'll still check it out and see if the change is something that can be worked around or if the ability to register a client with a self-signed certificate was removed.

I got Tech Preview installed from https://learn.microsoft.com/en-us/samples/azure/azure-quickstart-templates/sccm-technicalpreview/ but not encountering the same issue. Maybe it's something to do with your installation?

Any luck figuring this out @heinekmadsen ?

@heinekmadsen I just want to bump this one more time before closing this issue. Were you able to resolve this issue?
