Using a WPAD entry in each forward lookup zone where clients need proxy
server settings configured is an ideal way to automate the deployment of the settings.
Assuming DNS and a forward lookup zone is set up in an environment, auto discovery can
be enabled through the following technique:
1. Log in with admin rights to the DNS server.
2. Open the DNS Console (Start, All Programs, Administrative Tools, DNS).
A host record that corresponds with ISA is required, so it is necessary to set one up in
advance if it hasn??™t already been configured. To create one, right-click on the forward
lookup zone and select New Host (A), enter a name for the host (such as proxy.
companyabc.com) and the internal IP address of the ISA server, and click Add Host.
This hostname is used in later steps.
To create the CNAME record for the ISA server, do the following:
1. While in the DNS Console, right-click the forward lookup zone where the setting is
to be applied and click New Alias (CNAME).
2. For the alias name, enter Wpad, and enter the Fully Qualified Domain Name
that corresponds to the Host record that was just created (for example, proxy.
