Update proxy settings used by Software Updates role in SCCM 2007

Few months  ago I had an interesting problem at a client site that took me a while to resolve. So I want to post it here, maybe it will help others…

After a successful upgrade from SMS 2003 to SCCM 2007 SP1, I configured software update point, synchronized with Microsoft update to get the list of updates for products I needed and created a new list with updates required by clients. When I tried to deploy software updates it should download the updates to my SCCM server. Well, this step failed. PatchDownloader.log reported the following:

First I thought it was a stupid error, as I set (and checked twice) all correct information. Looks like proxy information was old and not updating with what I have set later in SCCM. So I needed to remove old information and set the new ones again.

I have checked the registry and I couldn’t do much as username and password was encrypted. Well, I used upddwnldcfg.exe (from <ConfigMgrInstallationFolder>\bin\i386\00000409 folder on a x86 machine) to delete all proxy information stored in the registry and added the new username, password and server’s IP address. After this, downloading updates worked perfectly. More information about configuring proxy settings using upddwnldcfg.exe, you can find here: http://technet.microsoft.com/en-us/library/bb892795.aspx
