Hi

I'm having 2 systems at my place and both are unable to ping themselves and the other. both are connected to a d-link 8 pin hub for which a cablenet pin is connected. i'm able to connect to the net on both the systems but unable to access on another. cable net is connected thru a PPP over ethernet protocol. verified netbios, they are enabled. tcp/ip numbers are 172.168.1.1 and 172.168.1.4 and subnet is as usual 255.255.0.0.

whats should have happened. sometimes one system is able to acess another and it's printer but the second time it is not so. by the way both the systems have 2000 pro in it. previously they are working well.

tell something might.
thanks
Ganesh

Do you have any firewall software installed?

Shouldn't the subnet mask be 255.255.255.0?

255.255.255.0 is a very common one, but I make the subnet mask to be 255.255.255.254 in this case ;(

Not saying that I'm right though, it's just what I think.

IIRC, a mask of 255.255.255.254 is invalid for a class C address (you'd end up with 126 subnets but NO hosts).

If you didn't want to use the 'very common' 255.255.255.0, use 255.255.255.224 instead, you'll have 6 subnets with 30 hosts on each.

This is irrelevant anyway, as it probably has nothing to do with ganeshkumar_kgk's original query.

If you disable NIS 2002 can you ping OK? If so, then the problem lies in the firewall configuration.

Thanks pal,

it worked. but sometimes one system is saying the computer is configured to access. some other times it is being accessed normally. now i've avg antivirus. both the systems have same users and same previleges. what might be the hurdle in that.

thanks once again.
