IIS 5.1 SSL Cetificate Missing

I recently did a system restore to recover from a driver installation
catastrophic failure for my ATi video. (System Restore is a real MONSTER in a
closet) In this process I ended up without an SSL Server Certificate for IIS
5.1. It installed fine when I built the machine and served its purpose for
quite some time. What's so peculiar is that I can't find it in the stores or
anything. My personal encrypting file cert is there and that's it. I don't
want to join a domain to get a cert. I failed to generate a new cert using
every scheme I can come up with.
How do I generate a cert for my server, please. (Don't let it be the
dreaded uninstall and reinstall dance please, please, please...) I have a
Root Cert Auth in the closet and the Subordinate Cert right next to this
machine, and I know how easy it would be to just join and autoenroll, but I
should be able to generate a cert somehow on XP Pro, shouldn't I ? Can't it
do even that piddly little thing ? I would think that to be shamefull that XP
Pro can't generate a vald self cert somehow. I don't really have any
experience with this stuff. But, all the buttons are greyed out in the
security tab for the website except the one that generates a text file or
request for certificate. All the behaviors I expect don't happen.
