Problem using logon

Dear,

My situation:

- I have a server (domain controller) in Amsterdam with windows 2003
server running.
- 3 clients in my office connect (for logon and exchange) to this
server with a vpn connection. They select "Log on using dial-up
connection" at logon screen to connect first to that server.

Now the problem:
I have a new windows 2003 server in the office who also should do the
same. But on the logon screen, there is no icon as on the windowsXP
clients. So I cannot logon to that server. It is a additional domain
controller, based on the first one.

Can someone help me?
Should I make a vpn connection as a startup service... Or what should
I do? Thanks for your advice!

Kind regards,

Thomas GEERAERTS
