Suse syslog redirects to a Windows server

Hi,
I have a Novell suse 10 linux box which runs syslog-ng. I am trying to redirect the syslog messages to a Windows 2003 server.

I have setup the syslog-ng.conf (changes are in italics):
...
source src {
#
# include internal syslog-ng messages
# note: the internal() soure is required!
#
internal();

#
# the following line will be replaced by the
# socket list generated by SuSEconfig using
# variables from /etc/sysconfig/syslog:
#
@SuSEconfig_SOCKETS@

#
# uncomment to process log messages from network:
#
udp(port(514));};

....

destination mail { file("/var/log/mail"); };
destination postfix_mail { udp("10.141.52.15" port (514)); };
log { source(src); filter(f_mail); destination(mail); };
log { source(src); filter(f_mail); destination(postfix_mail); };

The Windows server is open on udp port 514. But it doesnt seem to reflect anything on the Windows box? Do I need to make any more changes on the Windows end?

Thanks for all your help in advance.
