MSDE installation

I installed MSDE 2000 with parameters SAPWD='ahoj' SECURITYMODE=SQL
Installation was OK, I enabled all networks protocols in SVRNETCN.exe and
restared server.
osql.exe -L  found 1 server: (local);
But if I try to start osql.exe -U sa and write a password, osql says 'Login
failed for user sa'.
Where is the mistake?
The password is OK.
