Weird IIS error when transferring sites

[~J~]

I'm in the middle (or the start!!) of transfering several thousand websites from one server to another.

I've done one to write down a step-by-step and thought it went ok until I stopped the website on the original server and now the website doesn't work.

Got 2 servers, different IP addresses.
Changed the DNS records to point to the new server IP address.
Yesterday, Pinging the test site responded from the old server.
Today, pinging the test site gets a response from the new server.

Go onto www.newsite.co.uk and it shows me the site.

Go onto OLD server, stop the site in IIS, go back to new site in IE and I get a page can not be found!

Any ideas what this could be?

Cheers mate, will give that a look tomorrow.

Just couldn't understand how I can Ping a domain and get a response from the new server, but going into IE (or other browser) takes me to the old site.

Will definately do what you've recommended, thanks again.
