Hy snowmonkey,
First I would like to thx u for the reply.
The server is ISP server.
I think that it is a DNS server however, all I want is to be able to share documents between my 2 computers even when the server is down (in actual configuration I can’t connect to my other computer –share documents- when the server is down).
I can log in to my either computer with administrative right or user right. I use ftp connection or network mapped drive between those to which work fine when the server is working but does not work when the server is down.
I hope that my answer help you to help me

.
Thx.
