It may be due faulty Connection String or may be a firewall issue...
OR may be network connection failure can cause this error...
some more details please....

Have you checked the firewall? Windows firewall/any anti virus firewall that may be installed.

Can you ping the server itself? Is the server listening on port 1433? Can you telnet to 1433/sniff ports to see if its listening?

Do you have proper permissions on the box?

What troubleshooting steps have you tried?
