BUG #: 469450 (SHILOH_BUGS)
When you use Server Network Utility to disable Named Pipes as a communication protocol, the following Named Pipes-based features are not disabled:
Backup ... To Pipe ...
Restore ... From Pipe ...
This problem may also occur if the DISABLENETWORKPROTOCOLS parameter is used by SQL Server Desktop Engine (also known as MSDE 2000) Service Pack 3 (SP3).
Service pack information
To resolve this problem, obtain the latest service pack for Microsoft SQL Server 2000. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:

The English version of this fix has the file attributes (or later file attributes) that are listed in the following table. The dates and times for these files are listed in coordinated universal time (UTC). When you view the file information, it is converted to local time. To find the difference between UTC and local time, use the Time Zone tab in the Date and Time tool in Control Panel.
Note Because of file dependencies, the most recent hotfix or feature that contains these files may also contain additional files.
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.This problem was first corrected in Microsoft SQL Server 2000 Service Pack 4.
When you perform a BACKUP or RESTORE operation with Pipe as the destination while the Named Pipes network protocol is disabled, the following error message is logged in the SQL Server error log:
2003-05-01 08:59:55.25 spid51 BackupPipeFile:NamedPipesAreDisabled: Backup device '\\.\pipe\mypipe' failed to OpenMedia. Operating system error = 5(Access is denied.).
The following side effects may occur after you install this hotfix:
Console.exe only reports tape mount messages and no longer accepts user input. It cannot be used to continue, cancel, or end BACKUP and RESTORE operations. Because SQL Server periodically checks for a tape to be mounted, you do not have to signal SQL Server to continue a BACKUP or RESTORE operation. Mounting the appropriate tape is sufficient. To end BACKUP and RESTORE operations, use the Transact-SQL KILL command from a client application. You can also use the Kill Process option in SQL Server Enterprise Manager for the appropriate server and process (SPID).
The older version of Console.exe cannot be used to connect to a computer running SQL Server 2000 with version 8.00.818 or later. In this case, the Console.exe client application reports the following message:
Cannot connect to (null).
Console.exe cannot connect to a computer running SQL Server 2000 that is not listening on the Named Pipes network protocol. In this case, the Console.exe client application reports the following error message:
Connection to pipe \\.\pipe\sql\console failed. OS error 2 : The system cannot find the file specified.
