ATT dialer

Any one using ATT's VPN dialer? I've tried both version 5.09.2 and version
6.03 - neither works. [Both work on the same pc under the 32 bit version of
Windows XP Pro].

Version 5.09.2 simply hangs at authenticating server. Version 6.03 returns
an error about activating the local firewall.

Appreciate any help.

Thanks
