WORKAROUND
To work around the problem, use the TCP/IP Net-Library instead of the Named Pipes Net-Library to connect to the SQL Server database, and then back up or restore the database.
For the exact steps to set the TCP/IP network library on the client where you are performing the backup or the restore operation, see the "How to configure a client to use TCP/IP (Client Network Utility)" chapter in SQL Server 2000 Books Online.
When you connect to an instance of SQL Server by using SQL Query Analyzer, you can force the connection to use the TCP/IP Net-Library. To do this, type the name of the instance of SQL Server with the tcp prefix in the SQL Server text box in the Connect to SQL Server dialog box. This appears as follows:
tcp:SQL Server Name
