Running MATLAB through terminal services is not supported for R2006a or earlier.
However, in some scenarios, Microsoft Remote Desktop can be used to run MATLAB R2006b or later releases.
This error can also occur when:
  • Attempting to run MATLAB 6.5.x (R13) on unsupported versions of Windows later than Vista.
  • When you are on a Windows XP machine with a standalone installation and multiple users are logged into it. To resolve the issue in this situation, the additional users must log out.

As mentioned it has the problem in starting only, I tried to Initiate the program using TeamViewer and once it started I continue my remote desktop connection. Better to start it once anyhow. In my case i used team viewer.
Although the problem has been solved in Matlab R2019a.
Thanks Mathworks

move to \licenses folder, open the *.lic file, replace all the "SIGN=" to "TS_OK SIGN=", save and problem solved.
