[Nagiosplug-help] (check_nt) [NISClient] Cannot map "tcp" to protocol number

[Wolters, Alexander]

Hello,

when I try to monitor with the NISClient a Windows machine, I get that error
message.

Is there anybody else who gets this error, or knows what I have to change?
I'm using FreeBSD 5.0 with Nagios 1.0 and the latest NISClient 1.07.1.

Thanks in advanced.
