Hi,
Have you tried uninstalling and reinstalling of DLO?
Do you find the installation footprints in registry?
(HKEY_LOCAL_MACHINE\Software\Symantec\DLO\3.0\AdminService)
Note: Incorrect use of the Windows registry editor can have disastrous results on the operating system. Great care should be taken when making changes to a Windows registry. Registry modifications should only be carried out by persons experienced in the use of the registry editor application
Thanks,
