One site has a GUP that is up to date, but the clients are not getting current definitions
The definitions for all of the clients are from 1-30-2013. The GUP (Server) Is up to date. All of the clients at this site get updates from this server, and have been for a couple of months. How can I make sure that these clients are communicating with this GUP to ensure that the definitions are current.
Clients are Windows 7 64 BIT O/S
Server is Windows 2008 64 BIT O/S
