I do know that 10.100.40.11 is the address of my Service Tools Lan Adapter.
NSLOOKUP comes back that it can't be located. Our DNS server likely has no
record of it as it is not really a "system" name.
There was a 10.100.40.11 interface defined for our "normal" Ethernet line -
has been there since the install. Never had a conflict before today. Maybe
a PTF stepped on it. I know that this morning that interface failed and
drove me nuts getting into LAN console. If I tried starting it, it blew me
off completely - so I removed it. That is what has been confusing me - the
old "what was the last thing you changed?". Answer... just PTF's
The 1819 LAN adapter is a quad port and I'm wondering if it has multiple
MAC addresses. I haven't figured out how to tell.

On my i if I do NSLOOKUP '10.10.1.211' it will return me the name of the
machine currently using that IP address. Does that help?

C0. On the Ethernet line description, I find that my system is the D0.Not
a clue what the other is buit it is not one of our other two boxes.address].
I've removed the offending interface on the 520 but I can still see the
info from a PC command line via arp -a 10.100.40.11 [the dupe ip
Interesting that it shows the address as being dynamic but our DHCPserver
has no lease issued. We've always used the 10.100.40.xx static for theIBM
boxes.there
Does the 520 (8203-E4A) have two distinct NIC's and/or MAC's? I know
is a different interface for the LAN console but I can't find anyevidence
of another MAC address.list
Tracert does not show multiple hops that would help me find it or narrow
the scope.
Any other suggestions?
