Vista - Cannot WRITE to Vista from workgroup

I have a well established workgroup with one Vista Ultimate x64 and several XP-Pro workstations. All have the same users with the same attributes (user, administrator,...). All can access the internet via a router and all can READ files from any other shared drive/folder on the workgroup . All of the XP boxes can also WRITE to the other XP boxes as appropriate. So, the sharing and permissions are set up correctly for the XP-PRO boxes. The problem is that I cannot WRITE to the Vista box from any of the XP-PRO boxes . I have set it up with the same permissions as I use in sharing on the XP boxes. It does not matter whether I have enabled password protected file sharing on the Vista box or not. If I try to copy a simple text document to the Vista box, the error I get is: "Cannot copy New Text Document: "Access is denied. Make sure that the disk is not full or write-protected and that the file is not currently in use". None of these conditions is true. Any help appreciated.

Vista sharing is ALOT more stressful and tricky than xp sharing. If you right click on the file(s) you want to share and navigate to the sharing tab, you will see Network File and Folder sharing and Advanced Sharing. Be sure that network file sharing is enabled first. Then, under advanced sharing, make sure the "Share this folder" is checked and verify your permissions. (Everyone is a good setting, if you're not concerned about security) And make sure your network is private as well.

Hope that helps.

I'm not sure exactly what happened, but I now have WRITE access to my Vista box. "Network file sharing" was already enabled. "Share this folder" was already checked and the permissions were correctly set. I did add "Everyone" to try it out and, of course, it worked. But even though I think my network security is pretty good, I went back and removed Everyone. It still worked and now seems to work from both of my test XP boxes. Thanks for the help.

No prob.
