I have a problem in network sharing using SMB protocol.
I think it's related to IP-duplicating issue. How to detect this.
Note: I'm using Ubuntu on my desktop the other are using various OSs (win xp, vista, mac, Ubuntu).

One note though, if you are using DHCP, you likely do not have an IP addressing issue. What makes you think you have an IP-duplicating issue?
