Hi,
I have a question, I am wondering if anyone can answer.

We have a workstation, which was imaged some time ago. We login locally to this workstation using the [highlight #BABDB6](localMachineName)\Administrator[/highlight] account.
What we have yet to determine is, why the local computer name of this workstation, differs from the[highlight #BABDB6] localmachinename\account[/highlight] we use to login.

The local workstation name is registered in active directory, as [highlight #BABDB6]Machine1[/highlight], and if you select the local computer properties of this system, it shows the machine name as[highlight #BABDB6]Machine1[/highlight],
however, the local account we use to log into this workstation is [highlight #BABDB6]Machine\Administrator[/highlight].

How is it possible, that the local workstation name (Machine1), is not used as the local login account to this computer.
ex (domain\Administrator) [highlight #BABDB6]Machine1\Administrator[/highlight] is not how we log in, however, [highlight #BABDB6]Machine/Administrator[/highlight], is.


If anyone can provide assistance for how this would occur, it would be helpful.

Thanks







 
We found the problem. It has to do with the net-bios name being restricted to 15 characters, even though an AD object can exceed that. Once you join the workstation to the domain, the local machine name remains, but the AD/DOMAIN name for the local workstation is trimmed to 15 characters.

Ex. XXX-XXX-AB1234TEST (AD name and local machine name) - is trimmed to XXX-XXX-AB1234 as the local machine domain

Login : XXX-XXX-AB1234\Administrator is the user login account
