This security ID may not be assigned as the owner of this object

Hello,

So the scenario is like this. One computer and one laptop are used by the same user. Both of them have DLO 7.5 SP1 agent.

Syncing is configured on laptop but some files from Desktop are not synced to laptop and the error is "This security ID may not be assigned as the owner of this object". Which is really strange because the user is same.

I checked the owner of the files and the owner is that same user. 

Is there some solution to this?

Thank you for your help in advance.
