Hello Jacob !
Welcome to SW forums,
Could you kindly post the Admin tool picture with the red plus sign ? It would help us to understand better.
On your server start Archive server configuration application. On your vault name you have properties (right click). On Login tab you have Settings. Verify the users and groups. Usually you must make a group on domain server that contains the users that can enter in your pdm system. After that you can add this group to Archive server. You can also verify the registry key [HKEY_LOCAL_MACHINE\SOFTWARE\SolidWorks\Applications\PDMWorks Enterprise\ArchiveServer\CanAttachTo].
Thanks for the replies!
We actually discover the issue shortly after i posted this. As usual it was one of those "right in your face" situtaions. in the archive config tool and under the valut properties we were just missing the "use default settings" box. We assumed that was already checked and kept messing with the default settings but it was not passing those groups down.
