I have a similar issue.
I publish our Exchange servers thru two separate ISA servers. One in
dallas..one here in St Augustine. At various random intervals..usually at
least once or twice a month...the isa server stops forwarding requests on
port 25 to the exchange boxes.
No matter what I do...using hypertrm or telnet to connect to the external IP
of the ISA box on port 25 does not return the reply from the exchange
server.
Upon rebooting everything is back to normal. There is nothing in the event
logs to point to any sort of issue...I just don't get it.

ISA SP1
quite simply, DNS just stops working
randomly
wierd thing is:
NETSTAT on the ISA server shows nothing connected to the back end DNS server
when I have NSLOOKUP running from the outside
however
If I telnet to port 53. NETSTAT shows an ESTABLISHED connection.
I tried disabling/enabling the publishing rule this time and it did nothing.
PRE-SP1 had a fix for this that I applied and it seemed to do the job kinda
seems like SP1 undid this?
