I ran the CU on my Development Environment and had some errors in my Logs! Central Admin was working fine, but my Web Application wasn't.
Action 18.104.22.168 of Microsoft.SharePoint.Upgrade.SPSearchDatabaseSequence failed.
And my web application in IE showed this error:
Server error: http://go.microsoft.com/fwlink?LinkID=96177
I found this on TeEchNet with "This is a bug in Microsoft Office SharePoint Server 2007". But no explanation whether SP1, Infrastructure Updates or Cumulative Updates fix it! Anyway, I realised I had SP1 on my machine and am now installing the new December Cumulative Update to see whether that fixes it ;-)
I went down lots of rat holes:
Basically, I went into Central Administration and stopped the Windows SharePoint Services Help Search and then started it again and created a new database. Then when I ran:
stsadm -cmd upgrade -inplace b2b -wait -force
ststadm -o upgrade -inplace -url http://localhost:81
for my web application.
I then had to do an iisreset and hit the web application url and got a 404 error. In the logs I got:
Could not get Upgrade Area Url Mapping list. Aborting attempt to redirect 404 url.System.IO.FileNotFoundException: The system cannot find the file specified.

Although if I went to a sub site collection it worked fine!!?!?!
