Site connectivity - 28.Nov.2008 1:25:15 AM

Hi,

We have one site in India and other in Japan. Both India site and Japan site have their dedicated internet links. Since we have one Domain controller (single forrest) we have connected both sites via MPLS as well.

Both sites have ISA 2006 Standard edition and we are using it for Proxy only (No Firewall clients etc..).

Issue is that if internet links in Japan goes down we have to manually make changes either to Group Policy or by individually going to users workstation and changing the Proxy setting (by pointing it towards India ISA server).

Is there any way ISA does a polling kind of thing and in case finds that the internet connectivity is not available at a particular site, routes the proxy through other site. Say in case internet links in Japan goes down they get internet through India ISA as backup.

Hi,

configure WPAD on your network and go to Internal Network object properties. Go to Web Browser tab and select "If ISA is unavailable, use this backup route to connect to Internet:"
On the Alternative ISA Server: Select the India ISA Server.

Paulo Oliveira.

If you configure the Web Proxy clients in each site to use an automatic configuration script, either by pointing their browsers to it or allowing them to automatically detect it using Web Proxy Automatic Configuration (WPAD), you can use the Web Browser tab to specify an alternative ISA Server as a backup route.
