When I go to the control panel and try to update the Firewall client I get this error: 'The server is not responding when client requests an update'.
Try hard coding the name.
IP (of internal ISA interface) servername (netbios, not FQDN, like server1
and not server1.domain.com)
Example: 172.16.1.45 NTSERVER1 - If this works then it should be okay. Some purists might suggest using the
LMHOSTS file instead.
Reinstall the client or check the port settings. Make sure other services are not interfering.
