GSS 3.0 Agents not visible to console.

We have installed GSS 3.0 in 2 different servers, one is a Windows 2008/R2 and the other is Windows Server 2012 Std. Both of these server have GSS 2.51 on them as well. When we deploy the Agent to the Windows 7 workstation they do not show up in the console. 

Any ideas?

Thanks,

Andre' and team
