Actually there is a command line utility which can be used instead of Remote Desktop Connection- psexec.exe (from microsoft) which has a lot of commands to do many operations in the remote server, command line from client. It seems it will be much faster as there will be no GUI and it can be invoked in Perl through system command. But it asks me to enable Admin$ share in the remote server which is actually enabled there. Anyways will figure it out and thank you so much for your help.
