DNS or UDP Program Stops Working Through ISA Server

The information in this article applies to:


*       Microsoft Internet Security and Acceleration Server 2000

SYMPTOMS


A DNS server that is configured as a secure NAT or firewall client to
ISA Server may stop resolving names. When you restart the DNS service on
the internal DNS server or restart the Firewall service on the ISA
Server computer, the problem is temporarily resolved. A Network Monitor
trace may show that the ISA Server computer is returning "Destination
Port Unreachable". This issue could also occur with a UDP program other
than DNS. 



RESOLUTION


This problem is resolved in the latest service pack for Microsoft
Internet Security and Acceleration Server 2000. For additional
