I just recently implemented a SCCM 2012 RC server, and have built up a test environment for it. The clients are recieving update policies, but are not receiving notifications on available software items through the Software Center. They can go to the Application Catalog, where tey are able to see the available software, but are not able to submit a request, nor can they download and install the applications. I also noticed that they are unable to select the "I regularly use this computer to do my work" option from the "My devices" tab on the Catalog. All site components are in the green, and I have tried to check the logs, but I am unable to find anything that points to any issue. I am including screenshots of the 2 issues that I mentioned regarding the Application Catalog.
We are a Windows 7 shop, and all machines are currently running IE8. The AD Schema has not been extended, since our senior systems admin is worried about any negative repurcussions that may cause.
I am almost certain that this has to do with some settings in IIS, but I am too unfamiliar with it to go poking around.
Any guidance would be more than appreciated.
