Network problems on Mandrake 8.0 FREQ2

I have installed Mandrake v8 MandrakeFREQ v2 (I know it's Beta) and 
everything is working well except the network will simply stop working 
unpredictably. As soon as I restart the network using 
'/etc/rc.d/init.d/network restart', it works fine for a while, then stops 
again, and so on.
I have checked mail to root and found the following message (repeatedly):

>From nobody  Wed Jul  4 07:14:15 2001

Secs until next alert :

Detailed text (if any) follows:
-------------------------------
localhost: problem connecting to "localhost", port 23: Connection refused

I have never seen anything like this before, so I am at a loss. I checked the 
network with ifconfig:

---Sorry for the long post----
Any ideas on what I should look at next?
I appreciate any comments.
