First of all check your connection between DMZ And Domain Controllers in Internal network because if your TS is not able to fetch profile or settings from AD you may see this error.
Connection means all required ports should be opened.

Dear All,

I am trying to query/scanning the port between DC and remote server.

Yes. That is the most probable cause of the issue because your TS is unable to load profile settings.
