By default IIS 6.0 only serves statics HTML pages. If you are just serving
out static pages, there should not be any problem with IIS 6. If you are
running custom apps like ASP/CGI etc, you may need to specifically enable
the options to run them . Otherwise, try setting IIS6.0 to run in IIS 5
isolation mode and see if it resolves the issue. If it does, the problem is
probably related to the architecuture change in IIIS6.0 (http.sys and worker
process concept)

Some Additional Information for your reference when using IIS 6.0 Worker
Process Mode:

1. In Microsoft Internet Information Services (IIS) 6.0, when a request
contains a header name that includes a question mark (?) character or
another separator character, Http.sys rejects the request and sends the
following error message to the requestor:

 Bad Request (Invalid Header Name).

Additionally, when you use lowercase HTTP verbs like "get," Http.sys rejects
the request and sends the following error message to the requestor:

 "Bad Request (Invalid Verb)".

Refer to the KB for resolution/workaround:
FIX: Http.sys Rejects Requests That Contain Separator Characters
http://support.microsoft.com/?id=828726

2. KB: Information about ISAPI filters with SF_NOTIFY_READ_RAW_DATA in IIS
6.0
http://support.microsoft.com/?id=311852

3. Error Message: HTTP/1.1 Error 400 - Bad Request
http://support.microsoft.com/?id=247249

Hope it helps
