If you get the hardware alarm "Netbios Session closed" , you may find that you will have problems getting 2 or more display nodes to communicate initially with the IOServer. You may also find that after approximately 2 minutes they will connect and communicate correctly. 

The problem is that you have given the IOServer name the same name as the computer name for that server. This is causing a clash between the Citect I/O Server and the Windows peer to peer networking. This will cause failure of the Citect I/O server and the Windows for Workgroups file sharing.

You can solve this problem by either changing the name of the computer in the Windows control panel under network or change the name of the I/O Server. Citect version 3.2 now checks for this error and will display the error message:

Citect Server name <name> same as Windows computer name.

If you receive this error message you should change one of the names.
