I have a customer who is getting a blue screen of death - driver_irql_not_less_or_equal ndis.sys when they are connected over PPPoE to their DSL provider using speedstream software. When, in turn, they use their cisco vpn dialer back into my network, a blue screen will eventually appear sometime during the connection. The drivers and software are all up to date. The user is on an IBM laptop with a 3com pcmcia nic. Drivers are current. I have never seen this and am somewhat lost.

Please help.

I've never heard of this, either, but since the error is in the ndis.sys, it sounds like maybe there's a protocol or driver bound to that NIC that shouldn't be. When using PPPoE, usually it is best not to have any other protocol bound to the same NIC at the same time. If they are using this one NIC to connect both to a DSL line and to an internal network, trying to use it as a multi-homed machine, or moving it from one function to another without removing old protocols, this could very well cause problems. Check this out and see if it bears any relation to your problem. Hope this helps!

Unfortunatly, the internal network in question is on the other side of the internet, hice the need for a VPN. The PPoE has to happen first, followed by a VPN connection to the gateway. Nice try.

Try removing the NIC and run the m/c. You can even try to put the NIC in a different slot in the machine. Hope it hepls.
