PIX2PIX IPSec NT Domain Login Failure

I have successfully established an IPSec site to site tunnel with the 2 endpoints being a PIX 515 with 6.21ED code and a PIX 506E with 6.12 code.

The problem is that when I reboot the Windows client, the NT domain login fails. If I cancel out of the login dialog box and go to a command prompt and ping a host on the remote LAN, the tunnel comes up. Immediately after this, I can do a SHUT DOWN>>LOG OFF>> and do a successfull NT domain login.

I can see network traffic on the inside interface of the PIX when I reboot my PC and assume this is the client peforming its login process. But it appears that this is not deemed as interesting and therefore doesn't bring up the tunnel.

With the VPN client application, there is a setting that allows you to initiate the remote access tunnel prior to the login process.....I need the equivalent type of solution for this site to site tunnel.
