Try:
Select * Into <DestinationTableName> From <SourceTableName> Where 1 = 2
Keep in mind that this won't duplicate any keys or indexes. You must create a Create Script of the table if you wish to copy the full structure. That script can be used to build a new table with the same structure. If necessary, you can also dump the data into the new table.
To generate a Create Script when using Enterprise Manager, simply right-click the table and choose copy.
I hope this helps you.
