Luckily this problem is on my test network! I tried an evaluation product on my Exch2000 box. When I removed the product it hosed the Exchange installation. The virtual drive didn't show up and though users still showed mailboxes I couldn't remove them. I finally rebuilt my mail server and followed Microsofts Q paper on removing Exchange from Active Directory. When I install Exch2000 on the rebuilt server it only shows the Exchange task of enabling Instant Messager and nothing to do with creating user mailboxes. The Exchange server is a standalone and there is one DC. Any ideas (besides rebuilding the DC).
