ASP.NET 2.0 BETA 2: Hey, my ASP.NET IIS Tab is missing!

Chris Adams says this:
This is a problem caused by the change between Beta 1 and Beta 2.

To fix, check the following 3 regkeys -
HKEY_CLASSES_ROOT\CLSID\{FD5CD8B1-6FE0-44F3-BBFB-65E3655B096E} \InprocServer32

Under (expand) InProcServer32, look for the presence of a non- (example and remove it.
It has a reference that causes this to break.

If you do not have this MMC interface, you can use aspnet_regiis.exe aspnet_regiis -s
where path equals the location in the metabase where you want the mappings to change.
Note: There is also a switch to do this non-recurvisely if you desire.
