There are two methods that I can think of to accomplish this task. I think adding a specific feature to exclude specific computers would actually be beneficial so I will bring it up with the team.

In the mean time, here are the two options you have:

1) Move the Windows 2008 server to an Active Directory Organizational Unit (OU) above your "Root AD Container" defined in Admin Arsenal. This would effectively make the computer invisible to Admin Arsenal.

2) Deny Distributed COM rights for the account that runs Admin Arsenal.

For example: You run Admin Arsenal from the domain account called Tom.Waits. You do not want Admin Arsenal to perform WMI queries against the server "MyServer". You decide to run the command DCOMACLS.EXE (in your Admin Arsenal directory) to deny the account Tom.Waits WMI access to the system. From your Command window (CMD.EXE) go to your Admin Arsenal directory.

cd %programfiles%\brisworks\Admin Arsenal

dcomacls -deny *.R*:Domain\Tom.Waits -computer MyServer

You can verify that this took affect by running:

dcomacls -view -computer MyServer

You should see a minus sign (-) for Domain\Tom.Waits for the AL.R, LL.RA and LL.RL rights.

You can view the usage for DCOMACLS.exe here:

The best way to exclude machines from management is to have these systems reside in OU's located above the OU that you choose as your root for AA. Any machine that exists in an OU below your root AA OU (the OU that you choose to synch within AA) will be seen and inventory will be attempted.

We don't have a way to exclude certain machines otherwise.
