SCCM 2012 R2: No Source Pull Distribution Point available

A few weeks ago I was working with a customer on a global SCCM Project where the use of Pull Distribution Points would be a huge benefit to reduce WAN traffic between some of the major sites.

So we ordered a few new (virtual) servers and installed the Distribution Point Role. Everything looked ok, so we moved on and enabled the Pull Distribution Point option, but we couldn’t specify any source for the Pull Distribution Point.

I went back to my lab, where I tried to reproduce this behaivor, but in my lab everything worked just fine.

But my lab was running in HTTP mode and my production was running in HTTPS mode.

After some searching I found this in the docs:

“Although a pull-distribution point supports communications over HTTP and HTTPS, when you use the Configuration Manager console, you can only specify source distribution points that are configured for HTTP. You can use the Configuration Manager SDK to specify a source distribution point that is configured for HTTPS.”

Then I started to search for a solution that could help me automate this process for me, and then I found this great script created by an unknown Microsoft PFE, but all credits for the script goes to him
