What are you attempting to connect with? Have you looked at your connection string? Is it using named pipes or tcp/ip? If it's tcp/ip have you looked at the port# to be sure its correct? Are you using standard or nt authentication?

Please provide more info.


Thanks,

It may also be a firewall issue if you have one. Usually this error occurs if there is no network connectivity to connect to the sql server.
