Creating dot com subdomains on remote DNS and Win2000 server

How involved is this?

[Webwork]

I would like to create [UK.XYZDomain.com...] [Mexico.XYZDomain.com...] I've never done this before.

I run a colo Win2000 server that relies on my colo hosts DNS servers, so do I ask the host to create a DNS entry for UK.XYZDomain.com? If so, any related DNS issues that might catch me by surprise?

On my Win2000 colo server I'm using host headers and a single IP address for multiple domains, so how would I set up the subdomain?

Do I go through the standard Win2000 procedure to create a new virtual directory that responds to uk.xyzdomain.com www.uk.xyzdomain.com?

Thanks for any help.

Subdomains can be configured in iis. Just specify the accepted host headers.

If you want the user to use the same web-application, but with settings based on a specific entry point, point all possible host headers to the same web-app in IIS and detect the current host header from within your code. Based on the outcome of the detection, you can 'personalize' your web-app

Good luck!

Thanks Ward.

I'm left with the question: Is there anything that needs to be set up in the co-lo hosts DNS?

Do you know if http requests simply resolve to the DNS for XYZDomaina.com and then, routing to the subdomain is simply handled at the IIS level, as if a sub-domain is "the same" as a sub-directory?

I'm not sure, but i think you don't need to change any DNS settings. But i recommend to test it first ;-)

You must have the subdomains listed as hosts in
your zone. Although you can use wildcard entries.

Thus, for example.com, you would normally have:

host record = example.com
alias record = www = example.com

now you want to add:

alias record = web2= example.com

or

alias record = sub.web2= example.com

all of the above are silly examples,
your names will be something else.

Your other alternative if you are talking:
a.b.example.com

is to do a sub-delegation.

You will know that the dns setup is correct
when you can ping it by the new name.

added:

the reason you need to do this is that the
client needs to be able to translate the
name into an ip address.
