From the Forums: SMS Distribution Points Pool Stopped

In a recent thread, forum "super member" msutliff was having a problem where, after installing a new System Center Configuration Manager Distribution Point, the "SMS Distribution Points Pool" in IIS would just stop completely. Here's how it transpired…

The Problem

Msutliff: I added a 2008 r2 sp1 Distribution Point yesterday. I installed IIS then the 2012 client then made it a DP. Clients could not download today.  I noticed in IIS that the “SMS Distribution Points Pool” was stopped.  Starting it causes faulting application in the event log for w3wp.exe, module smsfileisapi.dll.   

I removed the DP role, watched SCCM uninstall it and then I put it back.  Same problem persisted.    

I removed the DP, uninstalled IIS, reinstalled IIS, reinstalled the DP role.  Problem persisted.

I changed the application pool “SMS Distribution Points Pool” property “enable 32-bit applications” to True.  Magically it starts without any errors but clients are receiving 500 and 401 errors (in IIS log).  If I browse to the URL I see clients request in the IIS Logs I get the IIS HTTP Error 500 page.   

I can browse the path in explorer using my regular user account. 

I’m at a loss as to what I should do here.  In process explorer I see w3wp.exe 32-bit and 64-bit processes.  If I change it back to 64-bit where it should be I see it start then crash.

The Solution

Mark ended up working with Microsoft product support and the following solution was given…

Msutliff: Product Support called me and said they have seen this before:

I hope this helps someone else.
