WSUS 3.0 SP2 Install - Can't connect to Server.

Question

I have a server with Windows Server 2008SP2 Standard, IIS7, which was rebuilt to replace the crashed W2003 system.  The original system was running the WSUS 3.0 role and IIS for an existing organizational website.  I was able
to migrate the website and now have installed WSUS 3.0 SP2 and picked “use default site” during the installation.  However, when running WSUS, I cannot “connect to server”. 
As far as I could tell, on the old system both the organizational website and WSUS sites were running on port 80 (In fact, I had access to a .WIM copy of the old system so can mount it to look at the old IIS6 configuration, and I had a
MSbackup that reconstituted WSUS\UpdateServicesDbFiles\ SUS.mdf and SUSDB_lob.ldf).
Can in fact both WSUS and the other website share port 80?  I see in IIS7 manager that /Selfupdate and /Content are listed in the Vdir section.  Is it merely that I have to configure something further in IIS to allow this? 
I see no evidence of another web port listed for WSUS in our firewall VLAN exceptions. 
Also, would using the backed up SUS.mdf from the old WSUS instance be worth trying to use with the new instance of WSUS 3.0 SP@?
Tnx…

Answer 1

Why are you looking for issues where they don't exist?  I suppose since I don't know why there is a problem, I'm looking for where the problem may lie after exhausting verification of all other proper methods listed in the MS technet
directions to prep for the WSUS 3 install, the install itself and the post install configuration, and the diagnostics information.  So my last most thorough uninstall/re-install try produced the same problem I have been getting each time.  They are
listed below.  It is not a firewall issue as traffic for port 80 is already allowed b/c of the existing organizational website.  Can I narrow this down and infer from the error messages below that they seem to indicate an IIS7 issue?
