Hi, Here's the situation: I have a network with 4 computers all running Vista Business. One of them (Main) is acts as a bit of a server to the others. It hosts files that ALL users need to see in its public folder and confidential files (for two administrators) in their personal directories (C:\Users\Username), it also hosts a printer (not an issue here). Another computer is supposed to act a bit like an access point for main (call this one Office). Office has all of the users that Main has (identical usernames and passwords), most of these users need only access Main\Public, but the two administrators need to access their own files too. The last two computers (call them Workstations) are pretty much identical, only have one generic user account on each (which is duplicated on Main) which only needs to access Main\Public. Also in the mix is a piece of management software the data for which is hosted on Main, but a client version runs on Office too. This requires that Office have a network drive set up pointing to a specific place on the disk of Main with a specific drive letter. Workstations are working fine as of the moment, I only mention them for completeness. So: what I have set up is a batch script that runs on logon for each user on Office that uses the "net use" command to set up the required connection to Main for the management software and uses the corresponding user on Main as is logged on on Office (e.g. if Dana is logging into Main, the command is "net use Z: \\Main\Datamove DanasPassword /User:Dana" ). This works nicely and everyone who needs to can access Main\Public and use the management software properly. The issue is when either administrator tries to access their own files on Main from Office. Each of the administrators (A1 and A2 we'll call them) has the folder C:\Users\A[1/2] shared on Main with the following settings: Permissions: Administrator accounts on Main have full control, nobody else has any access Network discovery on File sharing on Public folder sharing on (password required) Printer sharing on (password required) Password protected sharing on Media sharing off However, when I try to access these from Office I just get an "access denied" error. Now, I wouldn't mind if this "access denied" could be converted to a "enter username and password" although ideally this wouldn't happen either but the most important thing is that no other users should be able to access the administrators files. So basically, I think the problem is this: how can I stop Main from treating users on Office as foreign despite having identical user accounts whilst keeping the ability to have a network drive for all users of Office with the correct drive letter?

On the 'Main' machine, are the administrators A1 and A2 set up as local administrators? I imagine your are calling them 'administrators' because they are admins on 'Office', but they must be admins on 'Main' too, for your scenario to work. (because "Permissions: Administrator accounts on Main have full control, nobody else has any access"). This only allows local adminstrators access to the share. In a workgroup network, there are only local users, i.e. no machine has any knowledge of the accounts and permissions on any other machine (peer-to-peer).
