only can ping in 1 direction

I have 3 networked PC's in the same workgroup, all of which are running Windows 2000. 2 of them can ping each other, but can not ping the 3rd PC. The 3rd PC is able to ping the other 2, but can not be pinged by these first 2. When I have Netbeui installed, I am able to share files and print to the 3rd PC. When Netbeui is not present, I am unable to share files. In either case , I can not browse the other 2 PC's from this 3rd PC. It only sees itself as a member of the workgroup and does not see the other PC's in the workgroup. I have uninstalled and reinstalled tcp/ip. I am able to boot this same PC to Win 98 and these problems disappear. Obviously it is not a problem at the physical or datalink layer. It seems to be a problem with the way TCP/IP is configured with the W2K operating system. Any ideas as to what would cause this ?

 

Is Netbeui over TCP/IP enabled and the browser service enabled on all PCs?

If you use Find Computer with names does it see the others?

Have you tried: NET USE g: nnn.nnn.nnn.nnn

the n's being the IP address of another PC.

 

Thanks for the reply, Dan.

I do have Netbeui over TCP/IP installed. If I try to use Find Computer or if I use RUN and type in the computer name it does not find it, except in one direction, the same direction I can ping in.
I do have the browser service started on all PC's.
I have not tried Net use. I will give it a try.

 

The syntax:

NET USE drive: | \\computer\sharename /DELETE [/YES]

I forgot to include Share name.

Also you must have user accounts on each PC.

For example, if you want use B to access a share folder/resource in PC A, on PC A you must have a B user account. This requirement is new for Windows 2000 and XP. It drove me crazy figuring it out. The other option is enable the Guess account which is not recommended.

 

Thanks, I will try it.
