I have one cisco SA-540 firewall and one 2003 domain server, since last Friday, I can't open this website in IE 8, https://dod-emall.dla.mil
(only can open in IE), I have reboot the domain server and change the new firewall , but still has problem. but very strange is I can open this website on domain server, but all other computer can't do it. IE just said can't open this webpage. I have run ipconfig/flushdns on the domain server. check the service the DNS server and client is on. on the firewall I setup the static ipadress and DNS there.
And our other branch office using the same firewall and 2008 SBS, we can open no problem.
any idea for that?
