Bad Request (Invalid Hostname) issue for only one user.

Hi everyone, I have an issue where one user (and it seems like its
only this user) is getting the Bad Request (Invalid Hostname) issue.

I understand why I get it the error in most situations, but most if
not all users experience issues.

In this case, it's one user from one client having the issue. This
client has over 200 users and no one is experiencing any difficulty.

I have tried to log in as the offending account on our side (we are
using DotNetNuke) and was able to log in successfully and was unable
to replicate the problem.

Because that is the only information I have, I present this question:
What are the correct questions to ask this individual in order to
debug his problem? He is about 400 miles away, so sitting down at his
workstation is simply out of the question.

Thanks!

First thing to do is determine if its the user or the machine or both.

Have the user logon ot someone elses machine. Do they have the same
problem?
Have someone else logon to the users machine. Do they have the same problem?
Is the users proxy server settings the same as others?
Have the user and the someone else attempt to ping the server. Regardless
of whether the ping succeeds or not is the ping attempted against the same
IP?

Re: Bad Request (Invalid Hostname) issue for only one user.

- Does this user have a proxy?
- Does this proxy support HTTP 1.1?
- Does this proxy properly send the host header?
- What browser do they use (does it support HTTP 1.1, have they disabled
this somehow in the browser)?

That's some questions i would start with.

Re: Bad Request (Invalid Hostname) issue for only one user.

Hello.
This bug happens also with me, who uses a notebook connected directly
to a desktop, accessing internet through AnalogX Proxy. Internet
access has always been OK until that very moment I formatted my
notebook and decided to use the OEM Norton Internet Security 2003. It
seems to be a conflict between NIS2003 and AnalogX Proxy.
Does anyone know how to fix it?

Thanks,

Re: Bad Request (Invalid Hostname) issue for only one user.

A 400 Bad Request is almost never a server-side issue with IIS. The
question is what is wrong with your client configuration or the
proxies that it uses to access the Internet, and those questions are
best answered by support personel for your client or proxy.

If you think it is a problem with NIS and AnalogX Proxy, then you
should consult their product support personel for issue resolution.
