Samba 3.0.24 in SCO UnixWare 7.1.4

Please help me in troubleshooting my problem in Samba?
I tried to instal Samba 3.0.24 in our SCO UnixWare 7.1.4 but after installing the nmbd daemon is not running.
When i check the syslog from /var/adm, the following error appears:
Sep 30 13:04:22 unixeei nmbd[25169]: bind failed on port 137 socket_addr =0.0.0.0.

Thanks

Eric :confused:
