Nope - try that and it "completes succesfully" but not guest user is in the database (EM or sysusers)

USE myDB
>execute sp_grantdbaccess guest

works for me from QA (SQL Server 2000, sa login).

I've also tried

execute sp_grantdbaccess guest, guest

and both version with single quites around the parameters. In all cases the command says it completes succesfully, but the guest user does not show up in EM or in the sysusers table.
