I spent all day yesterday researching this site and others for a solution to this problem with no luck so I am asking for help.  We have a mixed environment of Office 2003 and Office 2007 and are using Exchange 2003 SP2.  Our Outlook 2007 users cannot see free/busy information for some users.  What we see are the "\\\\..." No Information.  The Outlook 2003 users can see the free/busy information.  I had a few that were showing no information in Outlook 2003 but I had those users run the /cleanfreebusy switch and those are fine now in 2003.  I tried setting up a DNS forward lookup zone for "" and pointed it to the A record for the Exchange server.  The instructions I used were a bit sketchy so I'm not sure if I did it totally correct.  It still does not work.  If I do the "Test E-mail Configuration" and uncheck Guessmart and Secure Guessmart, using only Use Autodiscover I get this in Results:

Autoconfiguration was unable to determine your settings!

In the Log section I get an error:

Autodiscover to FAILED (0x800C8203)

Yesterday I was getting more errors but didn't write them down or screenshot.  I think they were (0x80004003)

I am not expert at DNS or IIS but I cannot see a virtual directory in IIS6 for autodiscovery.

Please help.  I need to resolve this so we can schedule resources and have everyone see them.
