Kenn,

You have isolated from your question that the problem is not from the system side.
It is from the networking side.

Make sure the telnet port 23 is enabled in the firewall for the particular server.

THanks

Opening up telnet into your firewall is a no-no. Suggest you look at installing SSH. It utilises port 22.
The software can be obtained from http://www.software.hp.com/cgi-bin/swdepot_parser.cgi/cgi/displayProductInfo.pl?productNumber=T1471AA

Be aware that there is a later version that has been distributed and can be found here.

I don't ant to play the role of the points police, but please remember that people assist in the forums using their own time and resources. You record of points assignment is not good. 84 point assignments from 352 postings is not good.

Kenn,
I think you need to make the telnet port 23 allowed thuogh your firewall .
May be this point ia outside you question;but what about secuirty.
Why you do'nt use secure shell& use this port 23 for this purpose.
