Spidey07,
Alright smarty pants. I run a network of over 500 client PCs and 20 servers by myself. Patching doesn't get done without testing being done. Blind roll-outs are the bain of a Systems Administrator's job. Always, always, always test before roll-out. That's rule #1 of software updates, especially Windows updates. Granted, on a very large network, the scale of yours, it can be a pain to test, especially if you have various types of machines and various types of installs, but you still test, test, test prior to roll-out. I've spent 8 hours testing patches that I thought might be problematic or that did present problems to other users. Research prior to roll-out is the #2 step in the process.
Do you know that the feds are considering or at least have considered fining Sys. Admins and corporations for leaving exploits unpatched? That lit a fire under my behind and I've been more vigilant ever since, just in case it does happen.
