PLEASE HELP…can’t share files PART 2

my LAN consists of 1 win2000server & 1 win2000pro.

I am trying to share folders between the 2 and cannot, I have them
both in the same WORKGROUP and they have the same subnet, I have
rebooted them.

From the 2000pro I can see the servers computer name under network but
when I click on it I get ” ‘servername’ is not available” The network path is not found”

The SERVER & WORKSTATION services are started

The systems cannot ping eachother and neither can be pinged from an
outside system…when i type ipconfig – both have the same subnet & gateway
and everything looks ok.

The user accounts are the same on each system so that isn’t the problem.

Print & File Sharing are both enabled on each & rights have been given to the network

My network is a T1 connceted via a CISCO 1700 Router, the 2 systems
are on a 8 port switch…please help..thx
