1 Domain 2 Server 2 Locations Problem - Please help...

halaakajan

Hello Guys,

In our company they are currently developing an application which would be hosted on 2 locations(City A and City . What they want is that User from City A would use the server in City A and the user in City B would use the server in City B. How is that possible is there anything to change in the DNS (Server 2008r2) or it will be a program logic which needs to be changed.

Please help me on this.

Have you set up your sites in Active Directory Sites and Services? I'd start there, you can assign the subnets you're using in each site to each site. Then make sure the programmers know how program this application to stay with in the site.

Thanks for the reply. Is it possible to map two IP addresses to 1 domain name (www.app.company.com)? 1st IP in City A's DNS and 2nd IP in City B's DNS?

Windows DNS does subnet prioritization and should use the local subnet for the server.

Can you describe the infrastructure further?

You say it will be "hosted on/in 2 locations". Do you mean there will be 2 application/web servers? Are there DC's at this site? Are you using site proxies? Is the application a web app?

An archaic but very easy fix is to deploy a location-specific hosts file as a user logon script via GPO. If you already have site OU's then this would be fairly straightforward.

You'll want to look at netmask ordering. Description of the netmask ordering feature and the round robin feature in Windows Server 2003 DNS

lsud00d - There would be two locations and each location will have a separate server.
