Quick one from me today. Quite often I come across this issue where it tells me the SQLAgent service is not running on the server when trying to import an organization or install a CRM server.
9 times out of 10 this comes down to user rights. I believe the right it is being denied is interrogating the the windows server to get a list of services running so that it can check for SQL Agent. Which means adding the user as a sys admin to SQL often won't help.
Try adding the user to the Local Admins group on the SQL box as well and this error should go away.
