Its nothing to do with the syntax, it should auto use the username and pass of the user logged in. I have tried this on other networks and it runs fine, just not on mine.
Its also nothing to do with the acl of that user, as they can map it from my computer perfectly. I am led to believe that its that they use different system services to map the drive.
I think the net use command uses netbios name resolution. And my wins server is running fine with every client registered. Anybody got a good idea of what is causing this?
