I currently have several machines networked with a server, in a workgroup environment. Although each machine is named, and each machine's single user account is named, when I look (for example) in the Open Files section of Computer Management in Windows Server 2003 it lists each user as 'Guest'. Why is this not showing either the computer or user's name, and is there any way I can change it? Many thanks for any help

It would appear only the guest account is enabled on the server and the server has none of the logon accounts. Do these users exist on the server? What happens if you disable the guest account?

I think that is the problem - I only have the standard accounts (including Guest) listed in Active Directory, and I assume this is where the others should be. Does this mean that every user will need to log on to their machine with a password if I set the users up on the server (as they require a password in Active Directory)? I have tried adding two users in active directory, the same users on each machine, and giving them passwords that match the machine's user account password. One shows up but the other still shows as guess - is there a reason for this? Thanks for your help

You initially said the computers are in a Workgroup environment; not a Domain environment. So, AD is not applicable in this case. If the users are accessing the server, then they will need the same accounts in the User Accounts on the server as they have on their own workstations.

Thanks for the reply - it turns out although the 'User Account' in XP was correct the profile names were not. I added the names of each user in AD with passwords, and used the same passwords and logins to map drives and it all seems to be working ok - not sure if this is the best way to do it. I am making one office set as a domain soon so might end up doing all the machines as it seems a much better way of running things.
