MP not responding to HTTP requests – fixed

I have been more than a bit annoyed with the MP on my SCCM server. I have SCCM SP1 running on Server 2008. It is also using a remote SQL server that is running on Server 2003 x64 edition. In looking at the component status, it shows up as a fat red X. Looking further in, the problem is on the SMS_MP_CONTROL_MANAGER component. Every 60 minutes I have a message that comes up in that component stating:

MP Control Manager detected MP is not responding to HTTP requests.  The http error is 12029.

I was able to connect directly to the MP in my web browser by going to http://SCCMfqdn/SMS_MP/.sms_aut?MPLIST. When I do that, I get a list that includes the name of my MP. But I still have that pesky message. Then I took a look at the MPcontrol.log. It was full of error messages also…but this one gave me the clue to the problem. The messages repeat every five minutes, and they follow this pattern:

Call to HttpSendRequestSync failed for port 12345 with an error code.

Http test request failed, error code is 12029.

Successfully performed Management Point availability check against local computer.

That is the problem…it is attempting to connect on the custom port that I set up for client requests, but is failing. A quick check of trying to connect via http://SCCMfqdn:12345/SMS_MP/.sms_aut?MPLIST confirms it…it can’t connect. The root problem is that the Management Point availability check is attempting to connect to the MP over the custom port, but IIS doesn’t know what to do with requests that come in on that port.

So…open up the IIS Manager, click on Sites, the right click on Default Web Site, and choose “Edit Bindings…”. Click “Add…” and enter the custom port information. Close everything out, and the MP is much happier…and so am I. The next time it does its availability check it comes through as:

Call to HttpSendRequestSync succeeded for port 12345 with status code 200, text: OK
Http test request succeeded.
Successfully performed Management Point availability check against local computer.
