When you upgrade from SQL Server 7.0 Service Pack 3 (SP3) to SQL Server 7.0 Service Pack 4 (SP4), client computers cannot connect to the SQL Server 7.0 server through sockets or TCP/IP, and they receive the following error message:

Connection failed:
SQLState: '01000' SQL Server Error: 10061
[Microsoft][ODBC SQL Server Driver][DBNETLIB]ConnectionOpen (Connect()).
Connection failed:
SQLState: '08001' SQL Server Error: 17
[Microsoft][ODBC SQL Server Driver][DBNETLIB]SQL Server does not exist or access denied.

For a complete list of Microsoft Customer Service and Support telephone numbers or to create a separate service request, visit the following Microsoft Web site: Note The "Hotfix download available" form displays the languages for which the hotfix is available. If you do not see your language, it is because a hotfix is not available for that language. The English version of this fix should have the following file attributes or later:
   Date         Time   Version            Size    File name   --------------------------------------------------------------   04-Oct-2002  23:59  2000.34.4.0        45,328  Ssmsso70.dll     				

To work around this problem, add the account that is used to run SQL Server 7.0 to the local administrators group.
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.
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

  1. Install SQL 7.0 Server Service Pack 4.
  2. Configure the MSSQLServer service to use a domain account that is not part of the local administrators group.
  3. Restart the MSSQLServer service.
  4. 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.
