Sonicwall SSO can't see the loggedin user on WIN7 SP1

Hey guys,

We use SOnicwall NSA2400, I also setup Sonicwall SSO (Single Sign On Agent) on two boxes. This is the error on the server that runs SSO Agent

Failed to get Logged in User for IP: xx.xx.xx.xx; Error:Error:[11]Cannot create ActiveX component., Please check system is up, it is a windows machine, login privileges and windows firewall is turned OFF.

I checked the event logs on the box that runs SSo Agent and there are quite a few boxes spitting out this error. MS Firewall was turned off, I actually created an OU and a GPO, disabled MS Firewall, moved machines into that OU and forced group policy update. So, to the best of my knowledge the MS Firewall is turned off on these machines.

Any suggestions ?

Thanks in advance
