What rules do you have configured to allow this access?

ISA Clients >> Problem with a site throw my ISA2004 firewall SP2

We use sbs internet access rule.

All protected networks to external. allow all outbound traffic. It seems
like the proxy don't register the user. It stands anonymus in the logg. This
is how the log looks:

Destination IP Destination Port Protocol Action
Rule Username
1.195.149.158.86, 80 http allowed con
httpsout anonymus
Source destination URL
1.internal external http://www.malmoaviation.se/

The rule httpsout is following:

http
https
https server

internal to external.

we also been trying with Firefox and from diffrent workstations, with the
same results

I wrote this also in a swedish forum, at first some laugh at me. But when
they tryied they ended up with the same result. It didn't work throw their
ISA Servers either.

I found a hotfix from microsoft, do you think this one can be to any help?

5. ISA2004 SP2 Firewall Errors 

Since upgrading ISA2004 STD to SP2 the Firewall service quits with the 
following errors logged in event log. Note we have no extra application 
filters installed other than what ships with ISA2004. It runs on Windows 
Server 2003.

1.
Faulting application wspsrv.exe, version 4.0.2165.594, faulting module 
W3Filter.dll, version 4.0.2165.594, fault address 0x0008dcc5.

2.
The Firewall service stopped because an application filter module C:\Program 
Files\Microsoft ISA Server\w3filter.dll generated an exception code C0000005 
in address 6477DCC5 when function CompleteAsyncIO was called. To resolve 
this error, remove recently installed application filters and restart the 
service.
