Problems Downloading Software Updates

Question

I am running SCCM 2006 and I was trying to download and deploy an update that was obtained from Microsoft Update. In this scenario KB4577586 but this issue is happening to any update.

However any updates I try to download keep failing because it's trying to use a proxy server that does not exist. Here is a copy of the PatchDownloader.log file

I am not sure why it's trying to use the proxy server at 190.88.11.21:6813 which is not valid, and is not being used by my company. We don't have a proxy server in place so I can't add any settings to make this change.

Under Site System Properties "Use a proxy server" is unchecked.

From what I can see, ADR is working fine for Endpoint Protection and monthly updates.

Any ideas what other settings I could check to allow these updates to go through?

Answer 1

For anyone who comes across this and is running into the same issue I was able to find a solution.

UpdDwnldCfg /clean was one part of it.

The other step was to disable IP Helper. Once this was done, it no longer tried to use the proxy and the files were downloaded successfully.

Answer 2

Updated info:

Did a bit of searching on Google about VPCache and came across a solution to clear the proxy settings:

UpdDwnldCfg /clean

So this was able to successfully remove the proxy settings so I am no longer attempting to use that particular proxy IP address however it still fails to download. As you said this may not be a MECM issue but a possible security setting on the server itself.
