Hi Shawn,
I think you get credit for trying. Some people won't deploy a correct
split DNS infrastrucutre for a variety of reasons. Two social credits
for the effort ;-)

Well, that depends on your definition of properly. We do some proxying
of Intranet sites as well (for caching, plain old T1 across the pond to
handle
2 continents worth of traffic...) so we have proxies set to resolve to
internal dns servers. Anything that doesn't get caught by the routing
rules goes out to the firewalls. In support of your argument, though,
we do have the same internal and external namespace.... I got
absolutely _nowhere_ with that argument... Not enough clout I guess :)

Hi Shawn,
Another (better?) way is to configure DNS properly ;-)
Thanks!

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.
