I have a small office running 20 windows xp. All of them are in same workgoup and each user use same computer, they don't move around. So only one user account is created in each computer and those user accounts are different and require password to log on.
computer1 - Mary/password
Now the problem is when James need to access Mary's share folder over the network, it prompts for Mary's user name and password. But for security reason, Mary is not supposed to tell James her credentials. I know some other way can make this work by creating James's account (same user name and password) on Mary's PC. But there are 20 PCs, it's not efficient to do this. Or other way around by creating a share account, so when it prompt, the share account credential can be used.
I am wondering that if there is any other efficient way to do this and no user name and password prompt. (I know by installing a DC will work, but the company doesn't have the budget)
