Doing BCP In AdvenutreWorks:Copying Data From A File To A Table-SQLState=08001,NativeError=2 && SQLState=HYT00,NativeError=0,Why?

Hi all,
I copied the following code from MSDN2 bcp Utility:
bcp AdventureWorks.Sales.Currency2 in Currency.dat -T -c
and executed it in my C:Program FilesMicrosoft SQL Server90ToolsBinn>.
I got the following errors:

SQLState = 08001, NativeError = 2
Error = [Microsoft][SQL Native Client]Named Pipes Provider: Could not open a connection to SQL Server [2].
SQLState = HYT00, NativeError = 0
Error = [Microsoft][SQL Native Client]Login timeout expired
SQLState = 08001, NativeError = 2
Error = [Microsoft][SQL Native Client]An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections.


Please help and tell me what wrong with this BCP execution or with the database, and how to make this BCP working.

Thanks,
Scott Chang
