[Serusers] problems about the start and the stop of ser

[zhu qiang]

I have installed ser in my computer 1, my computer 1
is in a LAN, and I have another computer 2 in the LAN,
 I have a msn messenger 4.6 installed in 2, and I
configured msn 4.6 according to howto, I fill the IP
address of 1 in server name or IP address in msn
advanced configures. but when I want to register, it
says that the network service is currently
unavailable, but I can ping 1 form 2. 

when I start ser, I can stop it at the first time,
When I restart 
it, if I stop in immediately, it is ok. but if after a
few minuters, I want to stop it, it responses as the
following
/etc/rc.d/init.d/ser: line 195: kill: (4573) - no such
process
/etc/rc.d/init.d/ser: line 195: kill: (4572) - no such
process
..........................

Can anybody help me?
