VPN Client sending NULL Passcode

I have 1 PC that can run any version of VPN client and nobody can authenticate from it. VPN 3015 log says NULL Passcode string was sent. The PC have been rebuilt, xp2sp2.

Re: VPN Client sending NULL Passcode


Have you ever installed the soft-token client on that PC where you are

connecting from?

Can you do a search on that pc and see if the file STAUTO32.DLL exists?

The commonality of this issue was the installation of the Soft

Token client on the Computer, this installs the STAUTO32.DLL. If

STAUTO32.DLL exists, The VPN Client it will try to get the passcode from

softID and would then prompt for PIN even when not in new pin mode. However

if the soft-token client was installed then uninstalled and this dll

remained, you won't be prompted for a PIN since the soft token client is

uninstalled. This could cause the vpn client to send an empty password.

If this is the case, I would suggest you delete the STAUTO32.DLL, and test the VPN Client.
