2nd NIC causes Logon Failure

[NTSGuru]

I have a W2K Server (with all SPs/patches) set up with Active Directory and 2 NICs installed. The primary NIC which connects to the firewall/outside world works fine. The 2nd NIC is for VPN connections. However, whenever I enable the NIC and set up the VPN connection with the RRAS wizard, it causes problems with all my users logging in.

I have 30 Win98 machines connecting to the server to log on to the domain. Once the VPN/NIC is added, no one can log onto the domain. If the account is already logged on when I activate my VPN/NIC, then they can remain logged on until they reboot/log off.

The only way to make it so people can log back onto the domain is to disable the RRAS VPN connection, as well to disable the NIC associated with it.

I am not running DHCP, could this be part of the problem? This is very frustrating, as I'm sure you can all imagine.

TIA!

And the NICs have different IPs? Sounds like there is some sort of conflict...

I've had a similar problem with multiple NIC's in a server. For security I disabled some protocols on one NIC (external) but although Windows reported them as available on the other NIC (internal) they never worked. I found this to be the order the NIC's where loaded into the motherboard.

Hope this helps.

mattwray... yes, i verified that the two NICs have different IP addresses.

StellaIndigo... which protocols did you disable? i'd just like a direction to look in. changing the order of the cards in the box has not made a difference.

Thx for the help so far.

Why not just have the VPN connect to the first NIC and remove the second?

"No domain server was available" while the dialup connection is active

Symptom: you have windows 2000 domain controller with DNS, DHCP, WINS and Dialup connection. Whenever the dialup connection is active, none client can't logon and gets a message "No domain server was available to to validate your password. You may not be able to gain access to some network resources"

Resolution: On the server, make sure you don't have "Register this connection's addresses in DNS" checked under TCP/IP Advanced DNS settings. To check this, go to the Properties of the dialup connection> the Properties of the TCP/IP>Advanced>DNS, uncheck "Register this connection's addresses in DNS"
