We have a couple of Windows 2008 servers. They live behind a firewall and all outgoing communication is must be off.
I wanted to just use online Windows update. To do this I need to open access to some servers at Microsoft like the below. In our firewall you cannot input DNS names but only IPs. The IPs to these servers changes. If I do a nslookup one day I get one IP and when I try it the day after another. So I cannot get this to work.
· windowsupdate.microsoft.com
· update.microsoft.com
· windowsupdate.com
· download.microsoft.com
· ntservicepack.microsoft.com
New question:
How we able to now fix IP address range for above URL and including sub-net mask?
If we going to enable WSUS, we also need to know what is the IP range and sub-net mask for windows update.
