You need to add the port as an SSL port. There is a tool available to do this on ISAserver.org. It's called tunnel port. thanks, Amy Babinchak Harbor Computer Services | 248-850-8616 | Mobile 248-890-1794 NEW Mailing Address: Harbor Computer Service 29488 Woodward Ave. # 450 Royal Oak, MI 48073 Web http://www.harborcomputerservices.net<http://www.harborcomputerservices.net/> Client Blog http://smalltechnotes.blogspot.com<http://smalltechnotes.blogspot.com/> Tech Blog http://securesmb.harborcomputerservices.net<http://securesmb.harborcomputerservices.net/> Buy My House: http:// www.HomesByOwner.com/15490<http://www.shannonrealty.com/vassar_mls_tour.html> Are you an IT Pro? http://www.thirdtier.net<http://www.thirdtier.net/> From: isalist-bounce@xxxxxxxxxxxxx [mailto:isalist-bounce@xxxxxxxxxxxxx] On Behalf Of Neil Cassidy Sent: Friday, April 10, 2009 9:29 AM To: isalist@xxxxxxxxxxxxx Subject: [isalist] port 444 for SSL I am trying to access a clients sharepoint site, and get this error from ISA. Sorry I am ISA-deficient, but is it a legitimate request to allow 444 as an SSL port, and is that a quick change on my ISA 2004 server? Thanks.
