I've just installed NAV 2009 from the downloaded product DVD (from Mibuso: Thanks guys!). You have to remove the earlier NAV 5.0 + SQL... first. I've installed according to the first option (DEMO) on my own PC (Vista).
So, now I can use the Role tailored client of a sales person and I can login to the Classic Client (NAV database), but not into the Classic Client to (let's say) make a backup. So, maybe someone can help me to inform me which login/password to use for the SQL Client to have most rights?
And also: is there a brief description how to startup another role in the Role tailored client? I did not get a loginscreen, so don't know how to change to another role...
