SQLState = 28000, NativeError = 18456 Error = [Microsoft][SQL Server Native Client 10.0][SQL Server]Login failed for u ser 'A-9\Admin'.

my host name is A-9. but i am not sure about the username.how do i get it

Add the name of you database before dbo.[item]. YourDbName.dbo.[item]

Try delimiting the table switch or adding the -d switch

bcp dbo.item in "C:\item.txt" -n -T -S"A-9" -d MyDB

bcp MyDB.dbo.item in "C:\item.txt" -n -T -S"A-9"
