After performing a factory reset with the tool, it does not take the Administrator user or any other. How can I enter dataminer or be able to login?
After a Factory Reset, you won't have any groups present in your Security.xml, so the new user won't be acknowledged as Administrator
So, in addition to the steps described by Jens, you also need to add the following tag, so that group id=0 (Administrator) can be linked to your user.
<Groups><Group id="0" name="Administrators" systemkey="2013134847,-1342194689,-1,-3177985,-1,-1,2147483647,-1,-1,-2145386497" level="5" isCca="false"><Views><View readOnly="FALSE" editable="TRUE">-1</View></Views><Elements/><Parameters/></Group></Groups>
Hi Estefan,
After returning the factory reset tool, the only user left is the local administrator. Could it be the case that server where the DMA is running is still joined to a domain? If this is the case, you will need to make sure that you log in with the local administrator (when log in you could try as username: .administrator).
