Hi Ron,
This is Mike from the Norton Authorized Support Team.
The first step you should take is to run Windows Update on all of the machines on your network, until it informs you that no more updates are available. Next, re-create the User accounts on all of the machines with the proper permissions and make sure they are all in the same Workgroup.
In regards to Norton 360, you will need to enable the "Trust" control for the machines on your network. The steps to do this will differ depending on the version you have installed.
If you are using version 1 or version 2 of Norton 360 and have a valid license, you are entitled to a free update to Norton 360 version 3, which I highly encourage. Before I give you the instructions for updating, first follow the instructions I listed above and let me know what version of Norton 360 you are using so i can provide you with the correct configuration steps for media sharing.
Thank you,
Mike

Hello. I'm new to this site & forum, but it looks active & helpful.
We have a wireless home n/w which has always worked fine with the several XP machines we have in terms of file sharing. I recently added a new laptop running Vista Home Premium. After days of research & trial & error I can (finally) "see" & share files & folders FROM the Vista machine. However, the XP machines see the Vista machine & can map it as a n/w drive, but then cannot even list the folders.
The error msg indicates access is denied, even though I've set all the sharing & permissions I can find on the Vista machine to allow r/w access.
Any ideas what I might be missing?
Thanks in advance,
Ron
PS
In case you're interested, removing Norton 360 from the Vista machine seemed to be the key to allowing it find other computers on the n/w. I had already followed the red herring involving the "hotfix" from MS that had to be loaded onto the XP machines with no luck.
