If your CSNW client receives:

        NetWare Authentication Failure                                       You cannot be authenticated on <ServerName> due to the following reason: A connection to the server could not                                      be made because the limit on the number of concurrent connections for this account has been reached.                                       Do you want to select another preferred server?
the client probably either created a new printer or printed to an existing printer and logged off / on in a short time period.

In Windows NT 4.0, the workaround is to shutdown after a CSNW client creates a printer. If this happens when printing to an existing printer, disable all spooler logging:

1. Control Panel / Printers / File / Server Properties / Advanced.

2. Disable all Log Spooler options.

3. Press OK.

4. Shutdown and restart your computer.

In Windows 2000, just clear:

        Log Spooler error events                                      Log Spooler warning events                                      Log Spooler Information events
