configuring OMA/activesync with wxchange 2003 on a win2k server

we recently had to do an emergency migration of mail servers. we had to (unfortunately) migrate to a win2k server. I know it’s not the best option, but we had no choice. At any rate, I found all sorts of tutorials on the web, espeically http://support.microsoft.com/kb/817379
that assumes (I think) that you are running server 2k3, with iis 6.0, when we are running server 2k (at least until we upgrade hopefully within the near future). I think that I have to creat a new virtual directory, but I can’t, at least not with the method they describe in 817379. I think that it may have to do with scripts located in C:\Inetpub\AdminScripts but i am not sure. Can anyone help? thank you.
