About. NET 2.0 connecting to lan SQL Server 2000

The database was supposed to be completed this evening, but it was found that there was an error connecting other computers in the LAN with vs2005. At the beginning, the response may be a firewall problem, the firewall is shut down. Later, I spent a night on the Internet looking for the materials on the Internet. I couldn't see them, but I had to start all over the Internet. then I couldn't find a solution. I watched the stupid man watch a movie, I suspect that he didn't turn off the firewall, and then I asked him if he had turned off the firewall. He fainted and didn't turn it off. Alas ........... another night is wasted. The default port for ms SQL 2000 is 1433, as long as this port is open.
