We have an SBS 2003 network with 10 users running ISA Server 2004. When one of my users tries to acces a certan website with Https, they get the following error:
Error Code: 502 proxy Error. Connection refused (10061)
IP Address: XX.XXX.XX.XX
Date: 3/11/2011 2:55:15 PM
This is the only web site this user can not access. She has been configured for full internet access. The strange thing is as follows. When she logs onto another computer, she has no problem getting to the secure web site. Also, when another user logs onto her computer, they can access the web site. I am baffeled.
