hi buddy,
- first checkout if u r in the same domain.
if u r getting ur ip from a dhcp domain that is a good sign, which means u will be able to see others on the net.
- if u r in the domain and ur domain is a windows box then make use of smb client eg. u can use the command findsmb which will list out all the machines and their ip addresses.
or the best thing that u can to is install "line neighbourhood" , similiar to windows explorer.
why dont u come up with ur lan details?
