I'm at my wits end and hope someone can point me in the right direction. I have a Seagate 500 drive (formatted in FAT32) connected to my Airport Extreme via USB. I can copy (albeit slowly) from my Alum. MacBook to the drive without any issues. My Dell C521 Windows XP PC can see the drive, connect to the drive, and copy to the drive, somewhat.... It will copy approximately 900MB - 1.2GB of a file and then I get this message: "Error copying file or folder - Cannot copy [insert file name]: The specified network name is no longer available". A hint as to what is causing the problem would be greatly appreciated!!!
