Server sent command exit status 255

Hi
when I install OpenSSH 3.8 on Windows XP it works with the public key authentication without any error, but when I install on Windows 2003 it gives an error below in the log

Changed the shell in WinSCP to /bin/bash and SFTP server to /bin/sftp-server from WinSCP tab. Still getting the same error. This error occurs in Windows 2003. I can successfully login with public key authentication from an OpenSSH server installed on Windows 2000/XP.
