Hi everyone.... Here's the setup: PS 4.0 entreprise edition Windows 2003 SP1 MUI French Need VIP for IEXPLORE because i'm using bluecoat proxy with per ip rules. Now, i've troubleshoot everything i could and i pointed to the registry. Usually, when a user logs in, under HKLM/software/citrix/VIP the system creates a key with the session ID as the name. Inside that key, there's a Dword with the IP value in hexa decimal... For some reason, in my system, this does not occurs... If i create the key manually, it works perfect!!!! i've looked at the security of the key, everything is the same as my working servers. Anyone has an idea??? many thanks
