Connect via serial cable to computer.

I have a cassiopeia A-11 with win CE 1.0 and want to connect through cable series to a server Windows 2003 that it has running RAS, how configure the accesses and permissions on the server?
because when it is connected, to the few seconds it generates an error and it is not connected. the error message is the following
"You have been disconnected from the remote computer you dialed."

Do you mean that you want to sync your A-11 via serial with Windows Server 2003?

It's running a DUN RAS server, or it's running the RRAS service? There is an important difference.

I'm running RRAS server.
and what I want is to be able to connect via serie to the server, I read that in routing and remote Access I must add a port ' Communications cable between two computers' and with this win CE 1.0 is connected, but when is authenticating, the user is disconnected by the server.
what can i do?

thanks,
