I have a curious network problem. I use a windows XP Pro, SP2 box as a place to put spare drives and share them out to my network for data storage purposes. I share from the root of the drive, and everything was fine for almost a year. Recently, accessing both drives has been painfully slow, and I can no longer watch movies or transfer files straight off of them without painful wait times. They have both also started to give me "you may not have permission to access this drive" errors. My first thought was a permissions problem, so I turned on advance file sharing and made sure full control for everyone was checked, and they where. With growing frustration, I have re-installed the OS from scratch, and deleted the partitions of and subsequently reformatted both drives, only to run in to the same errors. The computer can be pinged and tracert'd by both IP address and name, and all computers are under the same workgroup. Any ideas?

Hi questionmark555, Are you using any Firewall, Anti-virus suites on your computer ? Did you try removing or disabling them on the first place ? http://learnitfast.blogspot.com

How old are the drives that your putting stuff on? If connecting via wifi, is the signal strength of the box consistant?

Maybe you didn't enable file sharing properly, check this share file with group and user permissions in Windows XP article to help you.. Hope it helps..
