The clients are windows 7 sp1 64 bit on all the machines. The install of the certificate went fine except for one machine. It just says the web page cannot be displayed in ie(with friendly errors turned off) and in chrome and FF it shows connection interrupted. The Advanced options for SSL (as in the TLS and SSL versions) are exactly the same in the different browsers on different machines. I even blown the profile away on the machine and recreated her, with the same effect. There is is no roaming profiles. Just folder redirection of desktops and documents folder.
Would anyone have any suggestions on where to go from here?
