Answer 1

Make sure that remote server allows connection to port 1433/tcp, e.g.:

using telnet client (in Windows 7 isn't installed by default, to install use Turn Windows features):

telnet 1.2.3.4 1433

or using nmap (port scanner)

nmap -sT -r -n -vv -p1433 1.2.3.4

If doesn't allow - check inbound firewall rules.

Answer 2

By default, SQL Server 2005 doesn’t allow remote connection so you have to enable it manually. So if @abatishchev's solution doesn't get you going; it may be you haven't set the permissions to connect.

Run the Surface Area Configuration Manager (it should be in the SQL Server folder in My Programs under Configuration Tools). Choose Surface Area Configuration for Services and Connections Select your server expand database engine and then remote connections and enable TCP/IP and / or tcp/ip and named pipes. Click Apply.

Whilst you are here check the SQL Server Browser is set to run. Expand it out and choose the service; change the startup type to be Automatic.

Try again in management studio express to connect to the machine.
