How to add a user to a group in SQL Server Management Studio?

I want to add the 'NT AUTHORITY\NETWORK SERVICE'user to the group PrivUserGroup. I can see both of them in the logons 开发者_如何转开发folder in SQL Server Management Studio. But i can't find how to add this user to the group.

(I need this to enable the a dynamics crm user to run reports in crm 2011)

The NETWORK SERVICE account is actually a Computer Account in Active Directory, named after the server. Search for the name of the server instead of a user account.

You'll probably need to restart the web server as well.
