Hello I have a network in which I share files and folders without a problem. I want to assign a drive letter to some folders. So go to my compute-> map network drive and go through the wizard without any errors. When I finish I can't see the drive on My Computer. How can I solve this problem? Thanks!

go to Run and type in cmd and hit enter. type net use and hit enter. Is the drive letter you mapped showing?

You have to be a member of the same Workgroup as the other PC and your account has to have "permission" to access the remote resource to even see it. You can't use the Administrator account (there's already an Administrator account on the other PC!), you have to set up a common user account to access it. On both your PC and the target PC create an account with the same userid and password, enable file sharing on the remote PC, turn on Sharing for the resource, and add the account to the permissions to access this shared resource. On your PC log in under this account, go to My Networking, and make sure you can "see" the resource on the network under that Workgroup. Then you can go in and map a virtual drive for it. You could create a user group, give permission for that user group to use the resource, and add accounts to this group as needed to make it easier to share \between multiple users but unless you have several users or several shared resources it's about as easy to input the account name directly. XP has a number of "default" user groups you can use but user accounts have to be added to these manually. You don't exactly *have* to log in on that account, btw. If you have a common user account between the two PCs you see and log into the remote resource from an administrator account on your PC and even map a virutal drive using the user account userid/password combo but you have to have the common user accounts and permissions set up first.
