Assume the following scenario: You try to configure
AutoDiscovery for Microsoft ISA Server 2004 Web Proxy Client by changing the
value of the msFPCFQDN
registry value to an IP address. In this scenario, ISA Server 2004 replaces the
IP address in the registry value with a fully qualified domain name (FQDN)
after you restart your ISA Server 2004 computer.
For example, assume
that your organization includes a load-balancing environment that uses an IP
address instead of an FQDN. In this scenario, the ISA client computers in your
organization may experience DNS and connectivity issues after you configure
AutoDiscovery for ISA Server 2004 to use an IP address.

ISA Server 2004 from using the FQDN to replace the IP address after you restart
your computer. To do this, create the following registry DWORD value:

Then, follow these steps:
| 1. | Click Start, click
Run, type regedit, and then click
OK. |
| 2. | Locate and then right-click the following registry
subkey: HKEY_LOCAL_MACHINE\Software\Microsoft\FPC |
| 3. | Point to New, and then click
DWORD Value. |
| 4. | Type AllowAlternativeFQDN, and
then press ENTER. |
| 5. | Right-click AllowAlternativeFQDN, and
then click Modify. |
