This cost me 2 days to fix it. And I have googled and tried so many different solutions, in the end I fixed it. 

1st of all, I think the key is, the PXE was working properly before the update, but not after it.


In the SMSPXE.log whenever you start a computer from PXE boot it will say:


Prioritizing local MP	SMSPXE	9/18/2015 3:22:49 AM	2908 (0x0B5C)
RequestMPKeyInformation: Send() failed.	SMSPXE	9/18/2015 3:22:49 AM	2908 (0x0B5C)
Failed to get information for MP: 80004005.	SMSPXE	9/18/2015 3:22:49 AM	2908 (0x0B5C)
reply has no message header marker	SMSPXE	9/18/2015 3:22:50 AM	2908 (0x0B5C)
PXE::MP_LookupDevice failed; 0x80004005	SMSPXE	9/18/2015 3:22:50 AM	2908 (0x0B5C)
PXE Provider failed to initialize MP connection. 
Unspecified error (Error: 80004005; Source: Windows)	SMSPXE	9/18/2015 3:22:50 AM	2908 (0x0B5C)


And I have tried uninstall this, that, re-apply images things like that, none of them helped. In the end, it suddenly became logical that I should have a look of MP. and turns out the configuration of MP,DP and SYSTEM are corrupted. Which made sense.

1. I did not read any manual for update, which I believe can causing problem.

2. When SCCM is updated, some configuration may not passed correctly(which I can accept and think it is reasonable),however it caused the communication disruption between MP and other roles.


Solution :

1. Make sure the settings of following areas are on same page:

A.  Administration , Distribution point-> Property:


B. Administration ->Site Configuration -> Servers and Site System Roles -> server -> Manage point -> properties:




Fix those areas and see how it goes.


I have done some extra to make it work, however I am not sure the above is enough because I have done the following first. I hope you can resolve the probem by above only however I also did this before. I know one thing for sure, if you dont do above, the following can not resolve the problem. 


0. Uninstall PXE from DP

1. Uninstall MP.

2. Uninstall IIS.

3. Reinstall IIS.

4. Reinstall MP.

5. Reinstall PXE from DP.


Anyway the problem is resolved. To verify it works you just need make sure the attached logs dissapear when PXE boot a computer.


UPdate 23/10/15 

After a windows update and restart today, SCCM broken again, same problem.

This time I focused on MP.  Especially at error:


Call to HttpSendRequestSync failed for port 80 with status code 500, text: Internal Server Error



1. Uninstall SCCM client, I believe this SCCM client is the reason the server went broken again, and I skipped this step last time. So even I got it fixed, it breaks SCCM again after restart, I hope this is the root cause since this problem exists since 2007(SCCM client installed on MP).


I also moved all sccm servers to a OU that has no group policy to prevent it install client or updates. Cant afford it keep happening.


So even uninstalled client, you still have to do all the drill to get it back since the configuration is ruined. Here are the procedures.

1. Uninstall PXE

2. Uninstall boot images from DP, uncheck PXE support.


3. Uninstall MP


4. Delete C:\remoteIntall, delete c:\windows\temp

5. Reinstall MP

6. Reinstall PXE

7. Add boot images back to DP, then back to PXE.
