Doubleclick My Computer
Choose Tools, Map Network Drive
In the screen that appears next, choose an available drive letter from the upper list box. Pick a relatively high letter so it doesn't interfere later with "thumb drives" or other removable storage. We'll use Q as an example because ... well, because that's what we use here for no really good reason.
Click Browse and browse to the network share you want to use
Put a check next to "Reconnect at logon" so you don't have to do this each time you log on to the computer
When browsing you will usually have to select Entire Network>Microsoft Windows Network> (your domain or workgroup name)> (your server name)> then the (C:\on the sever or DSW)
Make sure you gave shared the DSW folder by right clicking and selecting sharing and security. Select Share this folder as and if you are using XP home, select Allow user to change my files on the network. For XP pro, click on permission and check allow full control.
