Creating a WPAD entry in DNS
Create a WPAD entry in DNS
Configure a DNS entry on the DNS server of the domain controller of the network from which automatic discovery requests from clients will be received (usually the Internal network) as follows:
- Configure a host (A) record for the WPAD server. It is recommended to reserve a static DNS host name for WPAD, as described in Microsoft article 934864: How to configure Microsoft DNS and WINS to reserve WPAD registration.
- Create an alias (CNAME) record to point at the host record.
Configure an alias for the WPAD entry
- Click Start, point to All Programs, point to Administrative Tools, and then click DNS.
- In the console tree, right-click the forward lookup zone for your domain, and click New Alias (CNAME).
- In Alias name, type WPAD.
- In Fully qualified name for target host, type the FQDN of the WPAD server. If the Forefront TMG computer or array already has a host (A) record defined, you can click Browse to search the DNS namespace for the Forefront TMG server name.
The DNS Server role in Windows Server 2008 introduces a global query block list to reduce vulnerability associated with dynamic DNS updates. This may affect WPAD deployment. For more information, see About implementing WPAD.
