This problem concerns a network connection between what I'll call machine A and machine B. On machine A, I can use SSMS to connect to a local database with no problem. But I'm having trouble getting SSMS on machine B to connect to SQLEXPRESS on machine A. I couldn't even get it to find the instance of SQLEXPRESS on machine A until I created a Guest user account with full permissions for the folder containing the database file. But when I try to connect to the server I get the error message below. I admit that at this point I'm lost. I don't know anything about SQL Server permissions, accounts and all that stuff - I've only been a local database user/VB programmer till now. Can anyone figure out what I need to do, or at least refer me to a good book that will give me some direction? Here's some more info about my configuration;
I'm using SQL Server Express 2008. I have Sequel Server Browser running on machine A. I have also shared the folder containing the database file, though I don't know if I really need to do that. I have TCP/IP enabled under SQL Server Network Configuration from the Configuration Manager.
