A network administrator can control several of the FTP Server configuration variables. One such variable, Maximum Connections, can be set by using the Network option in Control Panel to define a value between 0 and 50. Any value from 1 to 50 restricts concurrent FTP sessions to the value specified. A value of 0 allows unlimited connections to be established to the FTP Server until the system exhausts the available memory.
You can specify a custom message to be displayed when the maximum number of concurrent connections is reached. To do this, enter a new value for MaxClientsMessage in the Registry, as described in "Advanced Configuration Parameters for FTP Server Service" later in this chapter.
