How to Install SCOM Agent on an Un-trusted machine

In order for SCOM to communicate with an un-trusted machine like in a WorkGroup / DMZ / different forest, you will have to import a certificate so that SCOM will trust the foreign machine and will be able to communicate with it. The most common example is a SCOM Gateway.
This topic is a bit complicated but if you use a guide like this you should be OK.

I added the files that you will need as well so you dont have to copy-paste it. Additional files: REQconfig.inf , certreq

First thing you will need is an inf file that contains the request.

Performance, SystemIT

Memory leak

Leave a comment

Memory leak – when the Available MegaBytes (memory\% available Mbytes) for the system has exceeded the threshold, system performance may be significantly diminish, this results in low OS and applications performance. End users will usually complain about slow computer performance and you probably get a help-desk call like: ‘My computer is running slow’, or server is running slow.

Memory leaks can be caused by:

  • Too many applications running simultaneously on the computer.
  • An application may be leaking memory over time.

To view the history for the memory\% available Mbytes, start memory available Mbytes in performance monitor or event task manager\performance.

Create SCCM Distribution Point with Powershell

Hi Sysadmins

You need to create multiple SCCM 2012 Distribution points fast and accurate!

Maybe you decided on upgrading your  environment to SCCM 2012 or your company purchased another organisation. In any case,

The reasonable way will be to use a script, and not use the GUI to do the task over and over.

The preferred scripting environment is Powershell, since it already has many Configuration Manager commandlets that can be helpful.

You do have to work with at least SCCM 2012 sp1 version for the following script to work.

The below Powershell script will read the names of the Distribution points servers from a file. See example for the file Here
