Question : IIS5.1 "Request Control Not Valid For this Service"!?!? HELP!!

IIS 5.1 WinXP SP2

[1] In IIS MMC the default website has a red error icon and states the following:
 
    "The Requested Control is not valid for this service"

[2] In addition, I get an Error when I try to open a web (open in FrontPage) from the MMC. Message states:
     
     "You need to intall the frontpage client software to open a web in FrontPage"

[3] FrontPage IS installed (even reinstalled it)...yet I cannot ...

     1. See any webs in the via Frontpage (for Local Directory) using any combination (computer name, localhost, 127.0.0.1) ...nothing works.

[4] I CAN however ADD FP Server Extensions to any of the sub-webs and THEN open THAT web in fronpage ONLY by specifying the entire path to the sub-web. For Example, I can open http://localhost/subweb. (from within FrontPage NOT using MMC)

but I cannot open http://localhost...with MMC OR FrontPage.

HELP!

This is a silly question, but can you see anything from a web browser (IE, Firefox) other than the built in ones?  I know they share code base with IE, but try the full blown.  Otherwise, I believe one of two things is happening:
1.  You have a corrupted MSC file for inetmgr.  An IIS re-installation may fix this
2.  You have a corrupted metabase.  Re-install IIS is the easiest way, or use a metabase editor (Metabase Explorer or MetaEdiit, whichever XP has) to try to repair the metabase manually.  (Not recommended)

Best of luck,
