On the linux system, if you "ping mohanlal", does it display the correct IP
address for the Windows system (reported by "ipconfig" command on Windows)?

Are you using the Cygwin rcp or the native Windows rcp command?  The native
Windows rcp command sends the login name exactly as it is set up in Windows
(including upper case characters) and this can cause problems.

If type just "rcp" at a prompt in Windows, if it displays something like
this:

Copies files to and from computer running the RCP service.

RCP [-a | -b] [-h] [-r] [host][.user:]source [host][.user:] path\destination

then that is the native Windows rcp command, and your problem could have
something to do with case of the user name (but that is just a guess).

rcp operates through the rsh protocol, which is fairly simple.  It sends the
local user, remote user, and command to the server.  The server then looks
up a name for the client IP address (fails if it cannot), then checks
$HOME/.rhosts and /etc/hosts.equiv to see if the hostname and/or
hostname/user is allowed (fails if not found there).  Then it makes sure the
local and remote users (the same user unless an override is specified in the
command) are valid users (passwords have not expired, valid home directory,
etc.).  If all is OK, it should allow the rsh/rcp.
