Bad Request (Invalid Hostname)

While trying to host a site on IIS /windows 2003 devleoped in ASP, we got the following error.
"Http Error 404 - Bad Request (Invalid Hostname)" .
Located the file C:\WINNT\system32\LogFiles\HTTPERR.log to see if the error could be diagnosed with error description. All the other websites were running fine.

Solution: In Web Site Advanced property Host Header value was specified. Removing the "Host Header Value" resulted in operating site.
