I have two pc's on network, one is running ubuntu 12.04 64bit and another is running windows vista ultimate 32bit. I can ping both the pc's from the other and I can browse their files using ip address, but the problem is both the pc's are not detected by the other while browsing in the network folder. I have also verified the workgroup name, its set as 'workgroup' in both the pc's. Now, I dont know what else to check. Any suggestions please?
