Joe,
Here is the XP output of "ipconfig /all":

And here is the SL "dhclient-eth0.leases" file:
lease {
interface "eth0";
fixed-address 192.168.1.100;
option subnet-mask 255.255.255.0;
option routers 192.168.1.1;
option dhcp-lease-time 86400;
option dhcp-message-type 5;
option domain-name-servers 192.168.0.1,216.177.225.9;
option dhcp-server-identifier 192.168.1.1;
option domain-name "domain_not_set.invalid";
renew 0 2013/09/15 04:02:33;
rebind 0 2013/09/15 13:42:29;
expire 0 2013/09/15 16:42:29;
}
I must say, to my untrained eye, it looks like the files display
equivalent information. Still a mystery why the SL browser response is
so much slower!
