"Network Not FOund"

[akasixcon]

I have 3 computers and one of them cannot be found in the network. I will name that computer "A". Computer A however can access shared files from Computer B and C. What can I do to fix this?

Can you please be a little bit more specific with your description?

When you say that it 'cannot be found' in the network, are you meaning that you cannot access it from Computers B or C?
Are computers B & C able to access the internet where as computer A cannot?

Assuming here that 'A' can see 'B' and 'C', but can't be seen by either of them.

What operating system(s) are installed on A, B, and C?

Are you using a router anywhere in the network? Switch? Both?

Does this network connect to the internet?
