Cisco VPN and Nortel VPN #2

This time we did a fresh installation and managed to encounter a new issue when both client are being installed.

The previous issue could be caused by McAfee antivirus/firewall as well. After we removed the antivirus from the PC, seems like both VPN client can work fine, for the first time, until a reboot, then:

The NIC will not have any IP address, it will be the same in all NIC currently installed in the PC, inclusive of USB, WiFi and LAN card.

ipconfig /renew will say that the adapter cannot be initialized or something like that.

Microsoft has told us to reset the Winsock/TCP-IP stack, still it is not fixed, some netsh script. Download their FixIt program and still it’s not working.

We have tried to remove TCP/IP protocol from the adapter properties and reboot the system and add the TCP/IP protocol again, still it is not fixed.

Then we have also tried adding TCP/IP v6 protocol and it is not fixed.

Finally, we tried to add IPX/SPX protocol into the adapter properties, and hey, the adapter is finally getting an IP.

Wondering what went wrong back there, IPX/SPX should not be used anymore nowadays, hmmph.
