Re: Delay in connectivity
Configure HP igelan Gigabit Ethernet interfaces
Output from "/sbin/rc2.d/S305hpigelan start":
======
This is just for possible clues. On Server, What is the status of network interfaces before they start to respond to ping? Is there any difference if you use IP instead of name from your PC to ping it?

Re: Delay in connectivity
is there DNS configured?
check DNS file entry!
any fake entry will also cause such problem.

Re: Delay in connectivity
What is this address? Did you say that this is a two workstation network with a simple crossover cable?
> 80.0.0.223, subnet-mask 255.0.0.0
Is there a reason to use a class A address with room for 16 million IP addresses? Why not use 192 through 223 as your first octet as in 200.0.0.223 with 255.255.255.0 as your subnet mask?
> netconf...
What else is in netconf, specifically routing information? With a simple crossover cable, you don't any routes.

Re: Delay in connectivity
is that the only details in the netconf file?
what about the network that Bill queried?
192.168.....
Also what does the /etc/hosts file contain?have you added the network address of the PC, which is what?
have you updated this? or how did you configure the network? with commandline or sam?
and has the network deamon been stopped and restarted since modifications
