Mozypro won't connect through ISA 2000 server


I need assistance configuring ISA 2000 on a Windows SBS 2003 to allow Mozypro online access.  I contacted Mozy and they require access via port 443.  I created what I believe to be a protocol rule for internet access for SSL but no luck.  The only way I can get Mozy to work is to change authentication from Integrated to Basic.  This allows Mozy to connect fine but then all the clients are prompted for user credentials every time they open a browser.  I'm thinking I'm not setting up a rule properly.  Any help would be appreciated.

Thank you.

Sorry, that product (ISA 2000) left any form of support some years ago and I haven't touched it myself since that time. Shame that whoever looked after your system did not keep the system up to date via the Windows Update guides. SBS 2003 SP1 provided a free upgrade from ISA 2000 to ISA 2004 (you had to request the CD's).

Since that time, ISA 2004 and ISA 2006 have both been introduced and replaced.

You need to be very careful trying to create new protocol rules - especially for 443 - as your outlook web access etc could well go dow the tubes if you get this lot wrong.

You can also let 443/tcp pass without authentication. Also it is possible to ask for basic authentication after integrated did not authenticate (Squid can, Maybe ISA can do it too)
You can run Basic and Integrated at the same time.

Anything that can use Integrated will use it,...all others will fall back to Basic.

I tried Basic and Integrated at the same time and clients were not prompted for credentials accessing the internet but MozPro still wouldn't connect.  I'm going to remove ISA altogether and just a hardware firewall.
Then you will have to reconfigure SBS as a Single-Nic Server.  Do it correctly or you will make a mess out of it.
There is a problem with mozpro and a proxy authentication You do not need to adjust your properly working infrastructure for their broken product.

HTTP specification explicitly describes proxy with authentication. mozpro sell their stuff and have eyes to read it.

I agree,...however ISA2000 is so old and because of limitations in it's design it is very difficult to work with.  Getting rid of it and going with a different firewall that is a separate device from the SBS box isn't a bad idea.  

SP1 of SBS Premium included the free upgrade to ISA2004 which would be easier to deal with.  That would be a good option to go with if one wanted to keep SBS in it's current topology configuration

Sorry for the late response.  I removed ISA altogether to resolve the issue.  Thank you.

No other options worked except removing the program.
Sadly substandard product win in the compatibility race.
