After installation of the Nortel Contivity client provided by my company, and rebooting as instructed, I continue to get the phrase "you must reboot after installing the Contivity VPN client. Please reboot your system" AT&T VPN is installed at the same time however is not needed as I have DSL connection. This problem occurs with or without the AT&T installed. I have a Netgear DSL VPN Firewall and Spreadstream DSL by SBC. The operating system is Windows XP. Please help
