http://www.ISAserver.org ------------------------------------------------------- Hi All I'm running ISA 2004 on an SBS 2003 (not R2) box. There haven't been any changes to the server for the past 30 days. In the past two weeks, a web site that we use stopped working (their end, was offline then came back online). Since they came back online we've been unable to access the site. I set up a workstation outside my ISA protected network and tested - the site will load normally. It does not load inside the ISA protected network. I set up a filter for one of my workstations and attempted to connect to the site. The only failure I'm seeing is for a port 443 connection. It identifies the protocol as SSL-tunnel and has an action of "Failed Connection Attempt". ISA identifies the rule as "SBS Internet Access Rule". My current "SBS Internet Access Rule" is set to allow HTTP and HTTPS from all protected networks to external networks for SBS internet users. There are no problems accessing other sites using HTTPS (including internet banking sites) from ISA protected workstations, only this particular site. Just been checking with other staff here - the exact same error can be seen by going to http://www.acer.com.au/ and selecting the "ShopAcer" link on the left hand side (actual site I'd noted the problem with is Acer's wholesale e-commerce site). Any assistance or ideas on how to proceed very much appreciated. Aside from adding a couple of rules for Citrix my ISA 2004 is running pretty much vanilla default rules set up as part of the SBS install.
