thanks for the help! i was able to connect the 2 computers already
However, i have another problem. When i was accessing the database from the server an error occured, 'Server user DPC/Guest is not a valid user in database 'SPCProduction' '(a database i created). And when i was checked SPCProduction in the SQL Server Login Properties Database Access, an error also occured, 'The user cannot be mapped to a login name.'
How can i access SPCProduction from the other computer?
