I have a senario where a OES Linux 9 server that has been running for
serveral weeks has dropped its ncp shares and is sending a RST when a
clients attempts a connection to port 524.

Nmap show that port 524 is not open on the server, explaining the RST.

A ssh session has been up during this time and VNC works fine.

The following processes are running and have been restarted.

924 ? Ss 0:00 /opt/novell/ncserv/sbin/ncp2nss
1964 ? Ss 0:00 /usr/sbin/slpd

Any thoughts on what next?

Regards, Andrew
