/ALLOWBIND (Prevent DLL Binding)
/ALLOWBIND:NO sets a bit in a DLL's header that indicates to Bind.exe that the image is not allowed to be bound. You may not want a DLL to be bound if it has been digitally signed (binding invalidates the signature).
You can edit an existing DLL for /ALLOWBIND functionality with the /ALLOWBIND option of the EDITBIN utility.
