I once had a well running network. I had my upstairs aand downstairs computers running XP and a network drive (WD Netcenter) for backups. I could exchange files, access the internet and even game between them. It was nice. Nice, that is, until I bought a Vista laptop. Oh, it was able to see the wireless internet connection just fine. (I life in a rural area and have an unsecured network - but I don't broadcast the ID for just a little security) Well, I wasn't content just to access the internet with it. I wanted to be able to swap files and game. Trouble is - I can't see the XP computers or even the WD Netcetner on it. Then - for added fun I bought an iMac. It too can see the Wireless internet - and even the WD Netcenter. The Vista can't see the MAC, the WD or the XP. (NAMED US-PC) The XPs won't see the Vista or the MAC (but can see the WD) (Named Upstairs and Downstairs) The iMac wont see the Vista or the XP (but can see the WD) (Named iMac) And they ALL can access the wireless internet connection (same router)..... Here is a screenshot of the Vista Network Map. Hell if I can make sense of it. Can you help me? I have 'My documents' set to share on all the MS computers. I have downloaded the XP patch. The network name is MSHOME. Now how do I get to swap files? How do I get the Netcenter working? (192.168.2.24 is it's network address) The Netcenter is the most important part of all... I've searched all over the internet and found many articles on the subject, but none which did any good. The version of Vista I have is Home.
