Hello Jay,
Here is an article that may help you:
302372 HOW TO: Configure Logging in Internet Security and Acceleration
Server
http://support.microsoft.com/?id=302372
Currently, the ISA name resolver cache holds entries for 6 hours. This is
independent of the local Operating System name cache that can be cleared by
"ipconfig /flushdns" at the command prompt.
The default time can be changed, including setting the value to "0" which
will prevent the ISA name cache from holding any entires. This will put
all of the name resolution requirement back onto the local Operating System
name cache that can be cleared manually. You will need to test this
setting in your environment since making this change can cause an increase
in server load. The settings are as follows:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Fpc\Arrays\{ARRAYGUID}\ArrayPolicy\Web
Proxy AND \Proxy-WSP
The value is "msFPCDnsCacheTtl", change the value on this key from
"00005460" to "0" in both locations above.
Thank You.
Diana.
