Logging out of a Domain Account

So I recently added a new system running x86 windows 7 to the network, and when I log out or shut down using a local account, everything works as it should. If I log on to one of the user domain accounts, however, these actions don't work. Instead, the start menu and icons disappear and I'm left with the desktop background indefinitely.

Unplugging the network cable and plugging it back in then makes the system proceed to regular log out / shut down procedures, but I'm not sure why... Any ideas on some setting that is mis-set?

Also, this only seems to happen the first time I attempt to log out or shut down since the last reboot. So, if I log in to a domain account and try to log out, it will do this "freeze". Then, I unplug the network cable and plug it back in, and then the system logs out of the account. If I then log back in and try to log out again, it will work fine. But if I reboot the machine, the problem returns.

So now I'm having this same issue arise on several new systems I'm installing to the system, so I must be doing something wrong. Anyone have any ideas at all?

make sure you add the users on the domain such as exec-users,exec-admins in your local administrator group
