This is a generic error. Pls confirm the following:
1) Can this user access the NUDF (Network User Data folder) from this client machine ? If yes, can this user "write" on the NUDF ?
The following sharing and security permissions should be used:
Share Permissions on the root NTFS folder defined as the NUDF
Administrator: Full Control
Everyone: Full Control
3) Does launching the DLO Agent using "Run as administrator" help ?
4) On the client machine, browse to the registry at the following paths and verify information such as
32-bit: - HKLM\SOFTWARE\Symantec\Symantec DLO
64-bit - HKLM\SOFTWARE\WoW6432Node\Symantec\Symantec DLO
