FIX SCCM Management Point Issues Internal Server Error 500 HTMD Blog

Let’s check what are possible options to FIX SCCM Management Point Issues. The SCCM | ConfigMgr | Management Points are an integral part of client communication.

Introduction

The MPcontrol.log and IIS logs (located at W3SVC1) are always been best friends when you troubleshoot MP-related issues. sccm mp internal server error is call httpsendrequestsync failed port 80 status code 500.

We were getting the following errors in MPControl.log and u_ex140703.log. I hope this post can help some of SCCM admins to fix MP issues in SCCM 2007 and SCCM 2012 environments.

MP List and MP Cert Test URL details

http://<ServerName>/sms_mp/.sms_aut?mplist
where <ServerName> is the NetBIOS name for the MP Server.

https://<ServerName>/sms_mp/.sms_aut?mplist

where <ServerName> is the FQDN for the SCCM MP Server if an FQDN is specified in the site system properties or the short name if an FQDN has not been specified.

http://<ServerName>/sms_mp/.sms_aut?mpcert

where <ServerName> is the NetBIOS name for the MP Server.

https://<ServerName>/sms_mp/.sms_aut?mpcert

where <ServerName> is the FQDN for the SCCM MP Server if an FQDN is specified in the site system properties or the short name if an FQDN has not been specified.

Troubleshooting Management Point

1) Removed the SCCM management point role and added back. MPSetup.log says everything is installed perfectly.

2) Can’t remove IIS role from the server and add it back because MP is server is SCCM primary server and it hosts SCCM DP, WSUS roles as well.

3) SCCM client was installed on the primary server so we uninstalled the client using CCMClean.exe and deinstalled MP with no success (restarted the server as well).

4) Performed in-depth analysis on IIS 7.5 and event logs etc. No traces of recent changes and issues.

5) Checked “SMS Management Point Pool” application pool, what we had noticed was SMS Management Point Pool –> Advanced Settings –> Enable 32-Bit Applications was set to TRUE.

6) Changed the SMS Management Point Pool –> Advanced Settings –> Enable 32-Bit Applications settings to FALSE. Restarted the IIS.

7) After the change mentioned in point 6, MPLIST and MPCERT started working. Also, we had noticed that all the GET commands related to sms_mp started working.

MP LIST TEST URL ==> http://MP-server-name/sms_mp/.sms_aut?MPcert

MP CERT TEST URL ==> http://MP-server-name/sms_mp/.sms_aut?MPlist

The following entries are from the IIS log.

8) MPControl.log at SCCM primary server started showing green signals with the following log entries:

Successfully performed Management Point availability check against local computer.~  $<SMS_MP_CONTROL_MANAGER>
Call to HttpSendRequestSync succeeded for port 80 with status code 200, text: OK  $<SMS_MP_CONTROL_MANAGER>

9) So Issue resolved? Tried to build a new machine and it got failed 🙁

Following entries in the IIS logs

CCM_POST /ccm_system/request - 80 - 10.10.10.177 ccmhttp 500 19 5 2
CCM_POST /ccm_system_windowsauth/request - 80 - 10.10.10.177 ccmhttp 500  19 5 234

10) After changing the application pool setting for SMS Management Point Pool (website = sms_mp http://localhost/SMS_MP ), all requests coming from the client to download policies and MPLIST- MPCERT started working.

However, when a client tries to perform CCM_POST using the following websites then SCCM server IIS logs were giving above mentioned 500 errors.

So, we have decided to check the setting on the website’s CCM_Incoming, ccm_system, and ccm_system_windowsauth application pools on IIS 7.5 server.

The following are the Application Pools details of each virtual directory and IIS site!

CCM_Incoming = CCM Server Framework Pool = http://localhost/CCM_Incoming

CCM_system = CCM Server Framework Pool = http://localhost/CCM_System

CCM_system_windowsauth = CCM Windows Auth Server Framework Pool = http://localhost/CCM_System_WindowsAuth
