Hi Tom, That won't generate a 500 error. Tom Thomas W Shinder, M.D. Site: www.isaserver.org <http://www.isaserver.org/> Blog: http://blogs.isaserver.org/shinder/ Book: http://tinyurl.com/3xqb7 <http://tinyurl.com/3xqb7> MVP -- ISA Firewalls ________________________________ From: isalist-bounce@xxxxxxxxxxxxx [mailto:isalist-bounce@xxxxxxxxxxxxx] On Behalf Of Tom Rogers Sent: Monday, June 19, 2006 8:42 PM To: isalist@xxxxxxxxxxxxx Subject: [isalist] Wildcard Certificates Tom, In your article entitled "Publishing Multiple Web Sites using a Wildcard Certificate in ISA Server 2004" at this link "isaserver.org/tutorials/2004wildcardcert.html", you don't mention anything about remote client configuration. If you use a Wildcard Certificate from an INTERNAL network CA, this internal network CA will not be on the remote machine's Trusted Root Certificate Store - so how do you avoid getting a 500 error on the remote client because of this? Thanx, -TRogers
