I can not seem to get my new computer running Window 7 Pro to join my domain that is on my Linux Server. I get a message that says: "the specified domain either does not exist or could not be contacted"

Hi, Could you please provide more information about the directory services you are using in Linux server? Considering this issue is also related to a Linux server and we have limited resources to help, it is also recommended that you contact the Support of the Linux server for help since they are more familiar with their products. Thanks.Nicholas Li - MSFT

This link seems to have the answer to your question: http://ggts.net/2009/05/17/joining-a-windows-7-system-to-a-samba-domain/ And if you are not running newer versions of Samba and OpenLDAP, which seems to be the ones compatible with Vista/Windows 7, here are the instructions to set everything right on your Linux Server: http://ubuntuforums.org/showthread.php?t=1330637
