I have XP SP2, Vista, and one 7 system in a local home network. Our family music server is an XP SP2 machine with share for MP3's and a share for other media content. The other XP machines can see and access MUSICSERV, the Vista machines can see and use MUSICSERV, however my Windows 7 system cannot "see" let alone use the shares. However, I can successfully ping the IP of that machine and it does show up in the Network Map. My 7 machine can only see Vista machines in the network, and none of the XP machines. I have tried most of the suggestions that I have found: ensured the basics that I am familiar with; workgroup name is the same across all computers, share is avialable and accessable by all the other computers as it has been for years, etc.made sure that advanced sharing settings are as suggested (network discovery, file & printer sharing, sharing so anyone..., all on, password protection off, and use user accounts and passwords)Left any HomegroupTried installing IPv6 on the XP SP2 machineTried disabling IPv6 on the Windows 7 machineTried "Enable NetBIOS over TCP/IP" in WINS confguration for IPv4 on both the XP and 7 machinesSacrificed a chicken under the new moon and spread the entrails around the Windows 7 machine in an effigy of Bill Gates.....Doesn't seem to be working. Any better ideas ? I have been working with computer networks since the early ages, so I am no noobie at this, but can't seem to problem solve this one. Any assistance is much appreciated.
