IIS6 and multiple domain names/multiple NICs?

Post by paul.huddl » Wed, 11 Jul 2007 00:09:47


I have a need to have a second and wholly unrelated website run on a
server with an existing site. Currently, the server is only using 1
of 2 installed NICs. There is a domain name that points to this IP
address and IIS is configured to (all unassigned) for the existing
site.

I know that there are some ramifications to using 2 NICs configured in
the same network segment, but I have no experience with this and was
wondering if I am attacking this in the wrong way. Is it possible to
connect the second NIC, get it an IP address (same subnet) and have a
domain name point to it and then in IIS seperate the 2 websites to the
actual IP address of the 2 NICs.

So I would have NIC 1 - 10.0.0.3 - www.domain1.com
NIC 2 - 10.0.0.4 - www.domain2.com

then in IIS i would have site1 (domain1) set to 10.0.0.3 and site2
(domain2) set to 10.0.0.4

Is that a scenario where that would work, or am I barking up the wrong
tree. I know that there are things that can be done with headers and
redirects that may also work, but wanted to see if this would be
effective.
 
 
 

1. Can I configure multiple domain names to dhcpd.conf "option domain-name"?

2. Can I configure multiple domain names to dhcpd.conf "option domain-name"?

I want to add another domain name to the search order but whn I tried
either the service doesn't start properly or from Windows the DNS
Suffix search order isn't displayed and or set properly. Example
scenario.

I first set the dhcpd.conf settings for the multiple names.
...
option domain-name "linux.net linux.org";
...


Then from Windows PC I run ipconfig /all
...
DNS Suffix Search List. . . . . . : linux.net linux.org
...

Then I run a ping command
C:\> ping www
Ping request could not find host www. Please check the name and try
again.

As you can it didn't work. However, if the option is set to
"linux.net" only, then the ping of www works. BTW, www is mapped to
the IP address of the DNS server from within the /var/named zone file.
When I ping the FQDN of www.linux.net everything works.

C:\>ping www.linux.net
