I saw that a lot on mine as well. The performance problems were fixed by
implementing a dns-related hotfix and setting the two following reg entries
in hklm\system\currentcontrolset\services\w3proxy\parameters:
SkipNameResolutionForAccessAndRoutingRules - DWORD - value of 1
SkipNameResolutionForPublishingRules - DWORD - value of 1
I don't remember the hotfix number off the top of my head, but it is
included in ISA SP1. I never have discovered the reason that it "loses
connections" with the upstream proxy.

I am having a performance problem with ISA 2k on a win2k server using an
upstream proxy. The speed of connection to internet pages from client pcs
through the ISA seems to crawl compared to using IE directly on the ISA
(by-passing the ISA controls and connecting directly to the up-stream
proxy). We have also noticed that the event logs regually report event ID
14130 - The Web Proxy service detected that the upstream proxy
'xx.xx.xx.xx' is not available. For more information about this event, see
ISA Server Help.
Any help on this would be great. If there is any other information that I
need to list on this let me know.
Thank-you.
