Only way I've found is to create and protect the first sheet and then copy to
another sheet. This retains the protection. HTH

Mhz, here is one way with a macro,

Sub Protect_All_Sheets()

Dim ws As Worksheet

For Each ws In ThisWorkbook.Worksheets

ws.Protect password:="123"

Next ws

End Sub

To put in this macro, from your workbook right-click the workbook's icon and
pick View Code. This icon is to the left of the "File" menu this will open
the VBA editor, in Project Explorer click on your workbook name, if you
don't see it press CTRL + r to open the Project Explorer, then go to insert,
module, and paste the code in the window that opens on the right hand side,
press Alt and Q to close this window and go back to your workbook  and press
alt and F8, this will bring up a box to pick the Macro from, click on the
Macro name to  run it. If you are using  excel 2000 or newer you may have to
change the macro security settings to get the macro to run. To change the
security settings go to tools, macro, security, security level and set it to
medium
