Answer
- Navigate to the ..\MailEssentials\Wwwconf\DebugLogs\SID.log file
- Check the SID (Security Identifier) from the last login that the administrator used; usually this will be another administrator account and it will end in '-500' or '-512'
- Add this SID to the file Usermanagement.xml (taken from the directory MailEssentials\EmailSecurity\Data\) in this format: (starting with GFI MailEssentials Release 2 the location is now \GFI\MailEssentials\Attendant\data\Usermanagement.xml)
<User>
<Sid>S-1-5-21-2011272598-51679964-1933221383-512</Sid>
<RoleName>
<string>FullConfigAdmin</string>
</RoleName>
<Username />
<IsGroup>true</IsGroup>
<Locked>false</Locked>
</User>
<Sid>S-1-5-21-2011272598-51679964-1933221383-512</Sid>
<RoleName>
<string>FullConfigAdmin</string>
</RoleName>
<Username />
<IsGroup>true</IsGroup>
<Locked>false</Locked>
</User>
- Replace the SID with the customer's SID from the SID.log
- Switch the mode of GFI MailEssentials to Local mode and then back to IIS mode
