Hello,

With that less information it's difficult to find the reason + solution.

To connect to a MS Sql Server with a Windows Authentification you have to add the domain account to security=>users and grant access.

Hi,

Based on your description,   you failed to connect SQL Server 2000 instance under the Windows Authentication mode. Generally, the error message “SQL Server does not exist or access denied” indicates the SQL Server service is not running or the name resolution process in Domain Name System (DNS) doesn’t work correctly.

Thanks.
