Consent.exe is the UAC command prompt that runs when you try to run an app with elevated privileges.
The IP address 199.7.71.72 maps to VeriSign Global Registry Services.

ok, as i said i am not sure about the ins and outs of this however i think i am not too far of the mark here."
"My guess is that the OP is running an application whose executables are signed by a certificate issued by Betrusted, Cybertrust, or one of their relatives (Verisign), and that the system is attempting to validate that certificate. Recall that the text (and colors) used in a UAC challenge window are different depending on whether the requesting executable is or is not validly signed."
Maybe the problem is the UAC, try disabling that by going to control panel, user accounts and family safety, user accounts, turn user account control on or off, uncheck the checkbox and click OK. Reboot.
Your firewall may be blocking it as well.
