I have worked with Vista for the past 2 months - with no problems at all.  I get to work today (30 Janurary 2007) and all of a sudden I keep getting this error message when I open my solution.

Unable to open the Web 'http://localhost/.....'. the Web Server does not appear to have the FrontPage server extensions Installed.

Now, I believe MS did a patch because my computer was restarted when I got in. By Default my applications always run as administrator (I know how to change the compatibility). I also have every IIS feature installed. 

 I spent 4 hours working on this and said "screw it", and I uninstalled - reinstalled Visual Studio. I still get this. I've deleted & Re-created the applications inside my IIS Default Website, but I still get this darn error.

I just applied SP1 for Visual Studio (Vista edition) and I still get it.

Any thoughts?

---Edit

Whenever I go to Visual Studio and go to "Open Website" and I click on IIS, I cannot see any IIS information. Instead i get" YOu must be a member of the Administrators group on the local computer to access the IIS metabase............

I am a member of the Administrators group (We are on a domain).

They just came out with about 7 updates today.  Here are the numbers, so you can look in to it more.

KB929685 (Important)
KB930857
KB928089 (Most likely this one)
KB931573
KB929735
KB929427 (Could be this one)

Hope this helps, these for me were all marked as either Important or Recommended. 

yea, the KB downloads were automatic, i'll try removing some of them. Thanks.

 This happened before I did the manual update for Windows Vista, and before SP1.

I Uninstalled all updates for Vista. I'll roll back to Friday and see if that works. It's very strange (And bloody anoying).

-- Restored back to Friday (3 days ago) and it still gives the same error messages. This is inane.

 It works on Monday, not Tuesday it's totally messed up - and My box is the only one (out of 7 running Vista Ultimate) that is messed up. 

I wonder if this has something to do with not being able to see IIS websites from Visual Studio IDE (Open Website).

ANy other thoughts?

Tried running aspnet_regiis -ga <all users I can think about>

and aspnet_regiis -i -enable

 those didn't work either.

It seems re-installing Vista Ultimate worked fine... but I shouldn't have had to go that route :(

Rick Strahl got the same issue with SQL 2005 here: http://www.west-wind.com/WebLog/ShowPost.aspx?id=10151

 It seems it's not just me.

Hi,

I have the same problem with Vista and vs2008. I suggest to open the site directly form the file system (not local IIS). It works for me. Use for debugging "attach to process" functionality instead of starting the site.

Bye
