Windows Update Error 0X8024402C

Although I generally use Shavlik's HFNETCHKPRO to patch Windows Servers, I recently stumbled across two cases where Windows Update failed to work and I received the error 0X8024402C.

I found Microsoft's article on the issue, but clearing all proxy entries wasn't exactly what I was looking for in my case. (One server was running Project server 2003 and had added an entry as part of the Project server install. The other servers were running Veritas' Enterprise Vault product and had been configured with some proxies as part of their install.)

My solution was to observe the current settings by just running "proxycfg" without any switches and then appending "*.microsoft.com;*.windowsupdate.com" to the bypass list.

For example:

Run "proxycfg" and obtain the results:
Proxy Server(s): https://project;http://project
Bypass List : <local>;project

then run

proxycfg -d -p "<local>" "<local>;project;*.microsoft.com;*.windowsupdate.com
