Google is bringing up nothing on this subject for me.
We had an administrator accidentally delete the "Default Web Site" rather than the virtual directories following these instructions http://support.microsoft.com/kb/883380. Now everything in ESM is grayed out when you right click the virtual server:
I recreated the "Default Web Site" and then tried the KB article method 1 again, but it didn't recreate the virtual directories in ISS and the virtual server is still grayed out. I've tried rebooting, I even tried reinstalling service pack 2 with no success. Why will Exchange not recreate the virtual directories? I assume it had some linking (maybe a registry setting) to the old "Default Web Site"?
Edit: I just tried method 3 in that KB article and no success either. Still just an empty "Default Web Site":
Edit 2: Solved (see comments).
