I attempted to setup an AD-HOC wireless connection between them. I setup a shared folder on each in the root of the hard disk. I checked both of the folders? permissions and they are configured for full control for the Everyone group. Both machines can see each other via My Network Places (or within explorer). I can access and exchange data when initiating the process from the Win2K machine to XP machine with no problems. But when I try to access the Win2K icon in My Network Places, I get the Username/Password dialog box. I have checked the shared folder & root drive security settings and they are set for the Everyone group (full control). Can you advise as to what I may have missed to solve this problem?
The most common reason for this is unmatched user credentials. When you perform peer-to-peer sharing in this fashion, each machine needs to have a user account that matches one on the other machine, with the same password and preferably the same access level. For perspective, I recently set up a Windows 2000 computer and attempted to access it from my Windows XP Professional machine. I couldn't obtain full access to the 2K shares until I created an account on the 2K machine that matched the username and password available on my XP machine. This is, as they say, "by design" -- peer-to-peer sharing is a lot less flexible than sharing from a client to a server.
