Windows 2003 Server Enterprise, Host Headers, & FrontPage Extensions Problems

[imported_ackote]

I am having a strange problem with Windows 2003 Enterprise Server.

I am trying to set up a new Windows 2003 Enterprise Server with IIS6 and Frontpage Extensions. I do not have a lot of IP addresses to use, so I decided to go with virtual hosting by using the Host Header Names so that all the web sites can use the same IP.

When I do not have host header names set for a website, I can get to the site's Frontpage Administration page and log in with the designated site Administrator. When I set the sites Host Header Name, it will not let me log in even though it worked a minute ago without the Host Header Names.

Anyone have any ideas?

Have you put the name(s) in your host header(s) in DNS?

Yes. I have a host name created on my DNS server for the new site. I can pull up the regular web page on another computer on my network.

I found the problem! It was SP1 and some security "enhancements" that was added because of it. I disabled the loopback check by adding DWORD value named DisableLoopbackCheck with a value of 1 in \HKLM\SYSTEM\CurrentControlSet\Control\Lsa. I don't know if there will be any "gotchas" that will pop up later, but it is working now. Thank you for the attempted assist.
