Sorry about missing details;

I use a cable modem. I have no other firewall software. I am using Norton
Anti-Virus. The program is Nortel VPN Client v4_15.

I do see the the NAT T is disable for the client, so I assume it is not
used.

I use the VPN to tunnel into my corporate network.

The issue is the last stage of the log in. Where the Client returns a
Banner Display box with security information. As a user, I must accept to
log on. The issue is the banner never pops up.

I have no pop-up blockers active. I did check.

Prior to SP2 update, I am able to run the VPN CLient. The firewall in SP1
must be disabled. Once SP2 is loaded, I have the problem, even with the
Firewall protect fully disabled.

Does the firewall still block ports when disabled?

Other users in my company use the VPn and have SP2 without issues.

I apprecaite the assistance.
