IIS conflicting with two network adaptors

I am running 2003 advanced server using IIS to host a site. I have two
network cards installed. one card is used for IIS and has a static
outside ip address. The other card is assigned an ip address but is the
local area connection with in the local network. If I have the local
connection disabled guests can access the site no problem. As son as i
enable the local area connection, guests no longer have access. They
get the error page can not be found.

I have the web site properties set to the correct static ip address of
the outside connection. Any ideas on what may be causing this?

Does IIS start if the other NIC is enabled? What is the status of IIS when
"guests cannot access the site"? Can you access the site (from the same
machine)?

It seems that I may have messed things up even more through trying
various troubleshooting steps I've found on the web.

Now it's invalid hostname (bad address) even with the 2nd network card
disabled. Ugh.

Just to give you a background on my ignorance here. Our senior admin
up and left mid project. It has fallen to me (the lowly help desk guy)
to ressurect this project by Monday. This is entirely outside of my
area of knowledge, but I'm sure it's going to lead to some resume
building experiance.

So problem #1 is now Bad Request (invalid Hostname) even with the local
network card disabled.

#2 is unable to access the site when the 2nd network card is enabled.

Thank you so much for your quick response.

Fixed the Bad Request Invalid Hostname issue by deleted the headers
someone told me to add.

Invalid hostname means that the host header value you sent to IIS (as part
of the HTTP request) did not match any of the host header names configured
in IIS. To resolve this:

- Open the properties of the website (in IIS Manager)
- On the Web site tab, click on the Advanced button
- Either remove the host header name, or use the correct one (i don't know
what you want to do, so i cannot say which one is correct).

The host header name should match what you use to access the website. For
example, the website www.gafvert.info should have the host header name
www.gafvert.info (and perhaps also gafvert.info).

For more information on host headers, also see:

"Understanding Host Headers in IIS"
http://www.gafvert.info/iis/article/understanding_host_headers.htm

Please fix the first problem (invalid hostname) before continuing.

For your second problem, i will check if IIS is the problem (i think the
problem is network related).

Once the first problem is fixed, enable the NIC that is causing problems.
Check the event log for errors, and verify that IIS is still running. Also
check if IIS is still responding by sending a request to IIS from the
server itself (use localhost). Does it respond?


With both NICs enabled, can you ping external machines (i.e.
www.google.com)?

By guests do you mean anonymous users? Or is it that people on the
same local network the private interface is on can't get to the site?

If it is the latter and you have a packet inspecting firewall such as
a Checkpoint between the private and public interfaces I may have your
answer.

Yes, please make sure you do not have a blank host header if this machine
will be facing the internet.

Hey,

Sorry for the long absense. It ende dup being a screwed up install of
IIS/Citrix Web Access.

After restoring from a base image and reinstalling IIS and all the
Citrix stuff, it ended up working fine after fixing a stupid network
config error.

Thank you all for your help.
