Wondering why, when VPN'd in, and RDP'd into a console-session of a SCCM(2007) Windows Servers 2003 client, that the "Display Available Software Updates" popup from the system tray does not appear. (Updates have already been completely downloaded to the client).
The main difference is VPN; when I am on the local LAN of the client, I can RDP into the console and the pop up immediately appears.
I've had this issue from multiple Windows PCs (XP\Vista\Windows7) and have tried more than one version of VPN, including the latest for Win7).
