We are running Netware 6.5SP3, mainly XP SP2 Pro workstations as clients

I have a situation where I have a computer (I'm not sure where) connecting
to Netware with an ip address I know, is there a way to determine it's
connection number? Send a message to the screen? I know I can see (through
remote manager) connections by user id, then I can drill-down to see what
the ip address is.
