Cannot find Network Path Error

I am woking on an NT4.o Server. When I browse Network Neighborhood I can see my Windows 2000 server listed but when I try to open it I get the error Cannot Find Network Path. I can ping the 2000 server and get a reply. On the windows 2000 server when I look at Network Neighborhood I can see the NT server and also log into it. Also when I try to use the printer on the NT server it says that it cannot find the network path. This printer is shared on the 2000 server. I’m very confused and need to find an answer
Thanks
