I ask because we had budgeted for patching software but management has decided we're too efficient. We patched around 900 NT/2000 servers and 15,000 workstations using various login scripts, batch files, psexec.exe, and plain old manual installs, etc over the course of 2 days.
I'm still in favor of an enterprise class patching product, if only to ease auditing and more granular distribution. We go through significant effort trying to re-inventory everything, trying to figure out which systems can get patched first, etc.
