Yep the SMC is managing all DHCP.

Only one DHCP server.  It's just windows boxes giving a generic pop up 
complaint about an IP conflict.  Reboot seems to resolve the issue.

Cool I'll check it out.  Sounds like a fun tool to learn more about my 
little LAN.

Well after digging around some today I found that I did have a not too 
often used server with the same static IP as my samba server.  Doh!  So 
I'm _hoping_ that will fix the locked files issue.  I had no complaints 
today about it.  :)

For the IP conflicts I changed the setting to update addresses on the 
SMC device to two days.  It was 2 weeks.  This is just me guessing though.

I'll do some more digging around.  Many thanks for the excellent feed back!
