I'm using ISA 2004 and SurfControl 5.0 for controlling the access to the
internet, from time to time i see in the real time logging window from
SurfControl blocked sites, which 5 minutes before was working correctly.

When the sites are blocked, it seems that the sessions off the users are
timed out, and they have to refresh there sessions, and they start to

Within ISA i have configured a rule which allowed workstation to connect
anonymous to the windows update site, which discussed in the following

After disabling the rule, and watching at the real time logging window,
i haven't seen this behavior again.

A other behavoir is that when a user types a URL for a site, IE times
out, when an other user types the same URL, the content is displayd in
his browser.
The first user have to hit refresh before the content is displayd.

One of the tuning tips was disabling logging, we where logging the ISA
logs to an external SQL box, SurfControl uses the same for his logging.

What could be the problem.
