The user name, the password or the machine/domain that you have entered are not correct. Try entering the details
again.

If the machine you are connecting to is running Windows XP and it is not participating in a domain, you will need to
change the
Network Authentication settings on the machine.
RPC Server unavailable
This message means that the attempt to connect to the server failed.
If you are connecting to My Computer:
Is the server application running?
Did an error occur that prevented the server application starting the RPC server?
Are you using the correct port name?
If you are connecting across a network:
Has the Wall Control-red server been activated? When Wall Control-red is installed on the server, a serial number must
be entered to enable the networking features.
If the server is running Windows XP Service Pack 2, is the firewall blocking the port for the server component? See
Windows XP Service Pack 2 .
Is the Wall Control-red server configured for network access? Security Policy
Is the server application running?
Did an error occur that prevented the server application starting the RPC server?
Are you using the correct port?
If a connection is possible with the Wall Control-red application either remotely or locally, you can use the Server Application
Manager dialogue to find out if the server application has been installed, is running and which port and port name it is using and
if an error occurred. In the Wall Control-red application, go to the
Configure menu and select Server Applications .
If a connection is not possible with the Wall Control-red application, you will need to look at the application event viewer on the
Wall Control-red server.
The endpoint is a duplicate
This error message suggests that an attempt to open a communication port failed because it is already in use.
If the Wall Control-red server has not been activated or the networking has been disabled in the Wall Control-red Administrator
dialogue or Wall Control-red has not been activated, the problem is with the port name.
