How to tell what service pack for Microsoft Commerce Server 2000 is installed?

Question

We have ancient Windows 2000 Server box running Commerce Server 2000. I'm trying to determine what service pack the Commerce Server has and I don't see any way to do that from the Management Console. I know the latest service pack for that release of Commerce Server is SP3, but this server is so rickety that I'm afraid to break something by attempting to install a service pack that may already be in place. How can I tell what service pack for the Commerce Server (if any) is installed on this machine?

Answer 1

I found there is a log file placed in the root Commerce Server program directory (which is C:\Program Files\Microsoft Commerce Server\ on this box) called CS2KSP3.log. That file indicates the date of service pack 3 installation. This solves my immediate issue, though a more concrete answer would be appreciated.
