Connection failed:
SQLState: '01000' SQL Server Error: 10061
[Microsoft][ODBC SQL Server Driver][DBNETLIB]ConnectionOpen (Connect()).

MORE INFORMATION

The following error message also appears in the SQL 7.0 Server Errorlog files:

ods Using 'SSMSSO70.DLL' version '7.0.1063' to listen on '1433'.
ods Error: 17826, Severity: 18, State: 1
ods Could not set up ListenOn connection '1433'..
ods Operating system error 10013., An attempt was made to access a socket in a way forbidden by its access permissions.

To prevent other sockets from being forcibly bound to the same address and port that the server-side socket network library binds to, the server-side socket network library in SQL Server 7.0 SP4 uses the SO_EXCLUSIVEADDRUSE option. However, to acquire exclusive access to the socket, the SQL Server application requires local administrator credentials. Therefore, if the account that is used to run SQL Server 7.0 SP4 does not belong to the local administrators group, this error occurs.

Steps to Reproduce the Behavior

Install SQL 7.0 Server Service Pack 4.
Configure the MSSQLServer service to use a domain account that is not part of the local administrators group.
Restart the MSSQLServer service.
Try to connect to this SQL Server by using the TCP/IP network libraries. You receive the "Connection Failed" error message that is described in the "Symptoms" section of this article.
