Powershell script and SCCM deployment issue

[mdrabble]

I have the following powershell script which I want to use as part of a task sequence to register a VM in Oracle box

Stop-Transcript

The script works perfectly fine if I run it manually, however if I run it as part of a task sequence it seems to hand

 

The log file the transcript creates shows the following-

Nothing to really indicate why the script is hanging.

Does the script work outside of sccm. Can you run it manually?

[markwilfan]

Also have you tried making a package and running it post deploy?

[mdrabble]

Yea, script runs fine manually and I have packaged it.

 

Ive set the execution policy to bypass.

 

The script starts to run as part of the TS as the Start-Transcript creates the log file and then it just sits there.

 

I'm wondering if I have the ErrorActionPreference correct and it is sitting waiting for some kind of response.

[markwilfan]

Oops sorry missed the middle bit of your post

[markwilfan]

So does the package run ok post deploy? I've had some scripts not work during the ts but fine after.

[mdrabble]

Well I say I packaged it - I created a package with source files containing the relevant files but didn't create the program.

 

In the TS I selected powershell command, selected the package and then typed in the script name and set the execution policy to bypass.

 

Will see if I can get the script to run manually as system in the morning

[mdrabble]

Ok, managed to test the script running as the System user and it runs run fine

 

Tested other simple powershell scripts - mainly msiexec commands and they all run fine.

 

Real head scratcher.....

You might need to import a module? Maybe SCCM isn't automatically installing a required module? Not sure which though
