Compacting password protected Access Backend databases from Fronte

I have been using the following code to compact and repair a backend that
is 
not password protected:

Dim stAppName As String
stAppName = "MSACCESS.EXE " & """" & Katalognamn() & "Test_be" & """" & 
"/nostartup /compact"
Call Shell(stAppName, vbNormalNoFocus)

and it works exactly as I want to. But now I have a password protected 
backend database (I am not using any profiles or so at all so it is just a

password nothing else)

I have tried the "/pwd xxxx" option but it seems like it wants me to also 
enter a user name and a password for that user - and I am not using user 
names for protection at all! How to solve this???

I am using Access 2003

Many thanks in advance!
