Hi guys,

 

I wondered if someone here can provide clarity regarding update sources for the SCEP client as I've hit a brick wall this side of the wire!

 

We have implemented the EPP role, configured AMW policies and deployed, setup ADR and tested and up until recently had no issues with SCEP or AMW update functionality. The SCEP clients are now failing to update their definitions. The updates sources, and order, are:

 

1. SCCM

2. Microsoft Update

 

Clients fail to update and provide the following error:

 

CODE: 0x8024402c

MESSAGE: System Center Endpoint Protection couldn't install the definition updates because the proxy server or target server names can't be resolved.

 

Having removed Microsoft Update from the Update Sources (as I believe there's no route to it), clients update their policies and now receive their updated definitions. When I examine the MPxxxxxx.log in ProgramData\Microsoft\Microsoft Antimalware\Support, it shows that the definitions were updated via MMPC. This causes a quandary because it isn't in the sources list.

 

I think my question is relatively straight forward... Are the definitions being updated from SCCM but incorrectly reported as MMPC or is there a default position within SCEP 2012 whereby it checks the MMPC regardless of what the configuration is set at?

 

Thanks,

 

Ian.

OK, a little bit of further testing has revealed the following:

 

Clients with a valid proxy server update their definitions when the proxy configuration is enabled. When the proxy is disabled, the client fails to update.

 

To me, this points at MMPC being credible as the update source but doesn't explain why the SUP isn't servicing requests from the SCEP clients...

Right. I've got something further to add to this. After completing some reading about SCEP, I think my initial question regarding MMPC has been answered. It would appear that the initial client definitions are updated from whichever of the five sources it has success with, whether they are specified in the AMW policy or not.

 

My problem is now with the error code I stated in my initial message. The WindowsUpdate.log shows numerous failures (all with error code 0x8024402c) and the WUAHandler.log doesn't vaguely reflect that shown in the troubleshooting example.

 

This is the WUAHandler.log content...

I believe the first set of failures represent the failure to connect to Microsoft Update. I've changed the policy to remove MU as a source and have instead added MMPC as we've obviously a route to this we can use as a fallback. The main issue remains with SCCM as the update source and I believe this is reflected in the last entries.

 

My only parting thought is that I need to get a proxy exception created for the SUP/EPP server to enable clients to reach it.

 

Any help you can provide would be fantastic.

 

Ian.

are you clicking on the Update button in the SCEP console or are you letting it update itself as per policy ?

I'm triggering it manually using the Update button after ensuring any policy changes are applied to the client. The machines that are policy-triggered are failing similarly...

I always like to try and tie up forum posts when I have the resolution, so here goes...

There was no Software Update Point configured on the Primary Site Server and the minute I installed and configured this role, the clients received their Antimalware definitions.

Thanks for your help guys,

Ian. :)

Hi,

I am new to SCCM 2012 EPP can someone please help me understand below points.

We have One Primary Server and all clients are configured to Update from This server

Currently in our setup When i go to Client and open EPP Console and Click Update it doesnt works.

But if i configure proxy in IE and then Try to update EPP it works.

Automatic Update is also not working.

I want my SCCM Server should update from internet and all my EPP clients should update from SCCM server rather than updating from internet.

Also is there any way i can configure proxy setting in EPP client so that they can update from internet as i have to login and enter proxy in IE and then Client updates but i dont want this.

 

Regards

Rohit Vyas

There is no way to configure the proxy settings, via the Endpoint Protection client settings. To see where the clients should be updating from, also check the Endpoint Protection client settings.

Hi all,

 

I have a problem with client computers when trying to update virus and spyware definitions from SCCM Endpoint Prot. server. I got this error:

 

0x8024402c

The definition updates couldn't be installed because the proxy server (in my case there is on proxy) or target server names can't be resolved.

 

What does it mean? The server downloads all the updates, put them into the correct update group. The update group is deployed to the correct collection of course. The client software gets the policy because I can see the day of the scheduled scan shown in the bottom of the window. I tried turning off the client machine's firewall, but no success.

 

The Endpoint Protection Definition update package was successfully uploaded to the DP.

 

The automatically generated update group (ADR for Endpoint Protection Updates) successfully deployed to the collection of the client machine. (if I check the deployments on the client machine at the properties, I can see both the EP updates and the Windows updates). By the way, no Windows updates arrive to the client as well...

 

What log files may help me? Log file from the server or from the client?

 

Thanks for your help

Attila

I'm having these same problems as the OP. Some computers and servers last week simply started to fail def updates. They where working for several months.

 

On the scep client, it says connection failed. The logs suggest scep is trying MS DIRECTLY opposed to my DP. How do I force scep back to my DP? I have checked my GPO and all is fine there. It points to my DP.
