Connection attempts over the shared memory network library fail on a server where GetComputerName returns a lower or mixed case server name.

When the shared memory connection attempt fails the SQL Server 2000 network library attempts to connect over an alternate protocol.

When you install any edition of Microsoft SQL Server 2000 or Microsoft SQL Server 2000 Desktop Engine (MSDE 2000) on a computer whose name is all lowercase or mixed case, Setup may fail, and you receive one of the following messages:

For MSDE 2000: For SQL Server 2000:

GetComputerName is used to obtain the local computer name. The client network library component (DBMSLPCn.dll) converts the name to all upper case. The server network library component (SSMSLPCn.dll) leaves the name as returned.

The failure is prohibitive to a SQL Server 2000 setup. A SQL Server 2000 setup prevents external connections by only allowing the shared network library connections.

If a shared memory connection can not be established, the setup fails when it attempts to configure the SQL Server server.

For SQL Server 2000:

The Sqlstp.log file contains an error message similar to: In the same Sqlstp.log file you can verify the naming failure by locating the following at the top of the log file:

   12:30:08 Name = MYSERVER, Type = 0x1
   12:30:08 ComputerName: MyServer
				

For MSDE 2000:

Run the following command so the installation does not roll back upon failure:

setup.exe /DISABLEROLLBACK=1 /L*v C:\temp\msdesetup.log
				

You must run this code so that the Cnfgsvr.out file can be collected. Using the /L*v switch enables verbose logging for MSDE 2000 Setup.

After the MSDE 2000 installation fails, when you review the contents of the Cnfgsvr.out file, you see an error message similar to the following: The naming failure can be located from the server parameter. The Msdesetup.log file has an entry similar to the following:

ComputerName =MyServer
