No input file specified – Windows Server 2012 Deduplication on IIS with php

My gaming clan forums started throwing a rather annoying random error recently and I couldn’t figure out what had changed to cause it. Essentially a page saying only “No input file specified.”

My forums are running phpBB on Server 2012 running IIS with (of course) php installed. The message would just randomly appear when posting replies to messages, or searching for new topics. It didn’t always happen, and clicking refresh would then load the page fine. I tried re-installing php, upgrading to a newer php and “tweaking” settings in the php.ini file. No difference.

Looking in the IIS logs would show a 404 error returned, hitting refresh (maybe a couple of times) usually returned a 200 and loaded the page. The file being loaded was present and everything seemed to be in order.

Endpoint Protection not managed or installed on ConfigMgr clients

This is one of those really simple and stupid problems that had me stuck for a while. I kept getting distracted with other things so it took a while before I got around to looking into it properly.

About a week after upgrading ConfigMgr 2012 to R2 I noticed some of the rebuilt servers didn’t have the Endpoint agent installed. The clients were working correctly, deploying windows updates and software deployments fine. Client Policy and inventory processing correctly, Endpoint Policy was assigned to machine in console and appearing on client (policyspy)

On new computers, Endpoint Protection did not install at all, and on computers when SCEP setup run manually, Endpoint policy never applies. Registry key indicates no policy is applied, even though “Generated Policy shows the correct values
