Navision 3.70 and daylight savings?

I've noticed that after we have a time change for daylight savings, the server will give clients a "building help index" progress bar before allowing them to log in.

This isn't a problem for users on our LAN as they just need to wait for the index to build to log in. However, our remote users connecting via VPN and Windows Terminal Services (Windows Server 2003) simply cannot start the program unless the administrator runs it locally first (to build the index), and only then can the remote users connect. If nobody runs the client on the terminal server locally, the remote users get a hung screen after initially logging into Windows (due to the "build help index" progress bar trying to popup, but it never does). I must add that the remote users are being forced to run fin.exe after logging into the terminal server. This prevents them from logging onto the server desktop for security reasons.

I did notice that when they ARE allowed to log onto the server desktop, then can run the client and it will build index and allow them to log in. So the issue lies in the fact that they cannot login while being forced to run fin.exe.

So my questions are:

1) Why does Navision need to "build help index" whenever there is a time change?
2) Is there a way to disable this?
3) If not, is there a workaround for remote users running fin.exe upon connect?

thanks,
