Error while executing the .rss script through command prompt

Hi,

I am executing the SSRS report snapshot through .rss script using command prompt as follows

rs -i reportsnapshot.rss -s http://servername/reportserver-v reportPathParameter="Report_Name.rdl"
 
Its giving me error as below.

Could not connect to server: <a href="http:///reportserver/ReportService2005.asmx">http://<servername>/reportserver/ReportService2005.asmx

even -u and -p options for username and password are not working for me.

Any help to overcome this issue is much appreciated.

Thanks in advance.
