Bob: I did some more checking when I got home last night. Still couldn't find 
any record of slpd updates. Status indicates that it's running. I get the 
'failed to close' message when I shut down - don't know what that's about. 

I got things working, again. Two things - the first was to enter the DNS 
servers from my ISP in my dhcp.conf file. That immediately brought all 
machines back to life. Then, I changed that entry to the address of my lan 
NIC, 192.168.2.1 as opposed to 127.0.0.1 - it seems to be continuing to work. 
It's a bit of a mystery - why it worked before, and why it stopped working 
for two pc's out of 5??? 

I was looking through the DNS bind server settings with Webmin last night, and 
I realized that there's a lot there I still don't understand - more reading 
to do... Thanks for the suggestions.
