I work with Windows Client and Server systems on a private network that cannot reach the internet. Problem is, many programs (like Subversion) cause Windows to attempt connections to www.download.windowsupdate.com to download a file called "authrootstl.cab" file. The direct result is that many programs that use SSL, like Subversion, block for five or ten seconds trying to resolve this host (which it never does).
I've tried putting this host to 127.0.0.1 or some other IP address in my C:\Windows\System32\Drivers\Etc\hosts file, but it still tries to look this up in DNS, and I assume it is bypassing the hosts file for security reasons.
Besides putting a dummy entry into a DNS server, which I cannot do, what other things can I try to stop or block this?
