Hi,

I installed sharepoint and had a default URL:

http://servername.mydomain.com/default.aspx

I changed the host header in IIS and configured DNS, and can now access
my site fine via:

http://sharepoint.mydomain.com/default.aspx

That works. However if I go to:

http://sharepoint.mydomain.com

I get a 400 Bad request. Yes, the Documents tab has "Enable default
content page" ticked and shows "default.aspx" as the top option.

This guy (http://channel9.msdn.com/ShowPost.aspx?PostID=263231) had the
same problem when he changed the port, rather than the host header.
Its as if IIS has hardcoded the original URL location of the default
document somewhere. I have tried disabling and reenabling the "Enable
default content page" option, as well as restarting various services.
Can anyone shed some light on how I can fix this?

Cheers!
