some interfaces were shutdown, but that was not all,, it was all my mistake :) i tried to see windows groups and shared folders, but it's just not working like that...
2 days before when I tried \\\\xxx.xxx.xxx.xxx it worked just fine... I tried that way few weeks ago but it didn't worked, and now I know way -- ACLs so I tought that router wasn't configured properly......but it was not all my fault, the guy from the firm that designed and configured all the network equipment said that it's not possible to do what i'm asking witkout windows server.....
but it was not for nothing, i've learned much from this.... :)
