Question : DNS Allias & Sharepoint AAM

Hi all,
         I seem to be driving my self crazy here. I have had this working once but cant get it playing ball again.

I have 3 sharepoint sites

1) server:1234
2) server:5678
3) server:9012

I want the following to link to the same pages

1) http://London
2) http://Manchester
3) http://Leeds

I can not seem to setup the CNAME working correct to point to the appropriate site. Every site seems to still point to the default page 80.

I beleive the setup should go DNS > IIS > AAM but need help on the first step.

Answer : DNS Allias & Sharepoint AAM

1. Open IIS
2. right click on London
3. go into properties
4. click advanced next to IP address
5. click add
ip adress = all unassigned, tcp port = 80, host header value = http://london

you may want to use the FQDN in the host header, or put in two entries there...

repeat steps 2 to 5 for Manchester and Leeds
