I am having some difficulties to operate my NDIS 5.0 intermediate driver
in conjunction with Nortel's Contivity VPN Client.
I start with a Dell laptop with an on-board 3Com NIC running Windows XP
SP1. The laptop is plugged into a docking station with an additional
identical NIC. I install the Nortel VPN Client software and reboot my
machine. When the system comes up I install my software which includes
an intermediate NDIS driver. The installation seems normal and no error
messages are displayed. However, after I restart Windows, I cannot
access the network (ipconfig only sees the VPN virtual NIC).
The above problem has not been observed on any hardware except the Dell
laptop, nor has it been observed on the same laptop when the
installation is performed outside the docking station. Also, if I
reverse the installation order (i.e. 1st my software, then Nortel's
VPN), everything seems fine!
Can anyone suggest what's going on? Any input will be most appreciated.
