When direct access to client machine is not available, verbose logging can be enabled and verbose logs can be collected remotely using following command.
Requirements:
Following command can be executed from DLO admin server to collect verbose logs for User1 remotely
Open command prompt as administrator on DLO administration server and execute following command:
>DLOCommandU.exe -RemoteExecute -LGT -WT 30 -U User1

This command enables Verbose logging for a duration of 30 minutes for User1
[-WT -- > Duration for which verbose should be enabled (in minutes)]
After 30 min, log gather tool is silently executed on the client machine and all the verbose logs are zipped and copied to users NUDF folder:
\\\domain-User1\.dlo\.remoteexecute\

Please copy and attach the 'RemoteLogs' .cab file to case using My Veritas portal for further investigation.
