I'm not sure if this is a more a database or sysadmin question, so let me know if it doesn't fit.
Because of some licensing agreements, I've been asked to find a way to restrict which computers on our domain can connect to an instance of SQL Server.
My original idea was to try and create a login trigger to check against a list of computers to see if they matched but I've managed to lock myself out of the server 3 times already. Further to this, apparently using
HOST_NAME() to identify the connecting client is not not secure.
How else could I do this from within the SQL Server environment or do I need to look at setting up Firewall rules elsewhere?
Just to be clear. We want it so any user can connect from a specific collection of computers.
