DSC is down

Hi community. I am facing a "DSC@myServer is down" situation.

Qlikview Directory Service Connector service not running.

I have started the service manually but it is still not running.

Then, restarted the server, same result, service not working.

There are many log entries for every restart, here you have one:

20180716T104039.394-0300 Information Initializing service

20180716T104039.514-0300 Error Shutting down the service since there are data with invalid encryption. To continue, activate the 'EraseUndecryptableData' config flag by setting it to true in the config file to erase the invalid data.

I am trying to modify the file Config.xml located at C:\ProgramData\QlikTech\DirectoryServiceConnector without success

The original content for the file was <DSCConfig><LogLevel>Normal</LogLevel></DSCConfig>

Trying with

<DSCConfig><LogLevel>Normal</LogLevel><EraseUndecryptableData>True</EraseUndecryptableData></DSCConfig>

and

<DSCConfig><LogLevel>Normal</LogLevel><EraseUndecryptableData>true</EraseUndecryptableData></DSCConfig>

didn't work.. I'm not sure if this is the file to modify...

Do you have any ideas?

Thank you.

I would suggest to contact Qlik Support and open a new case. The problem sounds weird enough to warrant the involvement of the absolute specialists in these matters.

After you made it to "true" and Save the file.

Restart the service.

When the service starts, the part of the data that is undecryptable is erased, but all other data is left intact.

Stop the service, open the configuration file and remove the “EraseUndecryptableData” entry.

Save the file and restart the service.

The service starts normally.

Now you need to re-enter the erased data in the QMC. All the undecryptable data entries have already been listed in the service’s log file, and that gives you a hint of what to re-enter in the QMC.

Just for the record, by pasting the config file from a working server it is up again.

Thank you all for taking some time to help me.
