SCCM 2012

SCCM 2012 R2 : Call to HttpSendRequestSync failed for port 80/443 with status code 500, text: Internal Server Error

Today a customer ran into a problem with SCCM 2012 R2. Clients didn’t get online and packages didn’t get distributed. After some investigationn I found the following problem internal Server error. As you probably know SCCM 2012 clients use HTTP or HTTPS (internet, PKI) to communicate with the SCCM server. This is how you can test this :

Test with the following urls in you browser :




You should receive a return with your SCCM server name and capabilities etc.

I didn’t and after some investigating I decided to reset the SCCM site. This is how you do that :



First open Configuration Manager Setup by installed programs (not starting the setup from the DVD!)


Choose next.


Choose the perform site maintenance or reset this site


Choose reset site with no configuration changes.

Now wait for 15 minutes and after that try it again. It can take some time before everything is set and up and running again.

SCCM 2012 Site Status Critical Component Server

While configuring a SCCM 2012 R2 server I noticed some Critical errors in the Site Status.
After some investigating I found the problem how to fix this. You must add the SCCM service account and the computer account(s) to the local administrator group of the site server.


Go to the local users and groups and add the SCCM service account and the computer accounts to the the group. (You manually have to tick the computer box to enable to add computers)


When this is done you noticed that the services are on green again :


Force SCCM 2012 Deployment

Sometimes you want to immediately deploy (install) a package and you don’t want to wait for the SCCM agent to start the task.

They are multiple ways to do this, one of them is to use the tools described in my previous posts.

The other way is to go the configuration menu of the client, configuration manager and go to “evaluatiecycles voor installatie van toepassingen” (dutch) and click Nu Uitvoeren (also dutch)

In English it’s called Machine Policy Retrieval & Evaluation Cycle.


Manually install SCCM client

Yesterday a customer asked me how to manually install the SCCM 2012 client. This is how you do that. Create a network connection to your SCMM Management Point server.

For example net use q: \\SCCMSERVER\SMS_SITEIDNR.

Go to the client directory and execute the following command :



Replace sccm-mp with the name of your SCCM management server and ofcourse make sure you use the correct sitecode.

After executing you instantly see ccmsetyp.exe in your running processes :


Great SCCM 2012 tool : PoshCAT

In the past I used the SCCM Client Actions Tools (link) but there is now a new successor called PoshCAT by Kaido Jarvemets. I found this tool so useful I decided to write a blogpost about it.

First : you can download the tool here.

After starting the Powershell script you notice the following screen :


In the upper right corner you can enter your credentials :


It’s easy to force client actions, like for example a hardware/software inventory :


Or restart the service or install the ConfigMgr Client manually :


Check for WMI problems :


WSUS and Endpoint options :


APP-V configurations :


Deployment actions :


And other options like ping, reboot etc.


I found this tool easy to use and very stable. The SCMM Client Actions tool (older, see start of the post) has some options PoshCat doesn’t have. I made some screenshots of this also :

Client schedule actions :


Client health actions :

I found a minor issue with the Check client version, I was running SCCM 2012 R2 and it reported that the client agent was outdated. I didn’t look into that, but the other options are working fine.


Client agent actions :


Advertisement actions :


Other actions :SCCM005

For the SCCM administrators, consultants, troubleshooters etc. it’s easy to have hold onto these tools. You are up and running in notime 🙂
