In 2 adjacent PCI slots are 2 LAN cards
Ethernet cable modem goes to one, crossover network cable to the second.

"Network Connections" panel sees the cards, reports them as L.A.C. and
L.A.C. 3

Where, please, is Local Area Connection 2, and why isn't it reporting?

System's working fine, just curious why new card became LAC3, missing out 2.

This occurred because when the second network card was setup, LAN 2 was
already present. If you move the NIC to a new slot, Windows sets it up as a
new LAN connection because it considers an LAN which is setup, but not
present, to still be valid and so will reserve the name in the event it were
to come back.

For example, if you set up two NIC's in a newly configured system, they will
be labeled "LAN" and "LAN2". Move the NIC to a new slot, and when you
reboot, the moved NIC will be named "LAN3" and one of the original LAN
connections will not be present. Move the NIC back to it's original
position and the original LAN connection should show, but LAN3 will not be
present. This is just how Windows works.

You can safely rename "LAN3" to "LAN2".
 
I think I understand the explanation, but am at a loss to understand how it
relates, since I didn't move first card (slot 3) when installing new card in
Slot 4. Nor have I rebuilt the system.
First LAN card directly replaced dial-up modem card in slot 3, 3 years ago.
Perhaps the modem was Local Area Connection 1. But if it was, then
logically, first Lan card would have been named L A C 2. Perhaps not, then,
(and dial-up modem is not a Lan card anyway). Still confused!

However, as said, was just curious, and as it's correctible by re-naming,
I'll do that and go away.

Thanks for the enlightenment. Len
 
The same thing can happen with even a seemingly minor change to the LAN
settings. It's strictly conjecture, but I believe Windows handles these
settings in this fashion as a method protecting against competing network
settings. For example, if you set up a NIC with static settings, the remove
the NIC, replace it with another card and assign the same settings, you may
receive a warning stating that another NIC is already configured with these
settings. Obviously, it's safe to proceed as that card is no longer
present, but Windows does remember the settings on the removed NIC.

I'm sure there's a way to remove those settings, but as it's easily
bypassed, I've never bothered trying.

I understand it's minor, but I also understand your curiosity, so don't
worry about "going away" ;-)

I don't know of any manufacturer that makes a router for a
dialup. They are probably made because I can make a NAT
router using a standalone Linux boxen.
I am not really sure about the LAC 2, 3 etc, etc. But in W2K
there was a dashboard in control panel to add and remove hardware.
Because of the WPA this is not in XP. They just leave your PC
cluttered with unused devices.
good luck
 
Uh, did you actually read this poster's question, or did I seriously miss
something? His post dealt with LAN naming schemes, not ICS. I actually
re-read the posts, but still can't figure out where you came up with
anything regarding a router for a dialup in the thread...??

And you can certainly remove hardware in WinXP as well as rename LAN
connections so that your system is not "cluttered".

So I leave you with a "huh?"
 
Yes I did read the __WHOLE__thread. His very first post was
about a router. LAN naming schemes. WTF....Network connection
1 is a device not a naming scheme....

Hmm, let's see...LAN cards, as in Local Area Connection, as in
Network...nope, no dial-up connections here. Maybe you're talking
about the cable "modem"? A little help; if you're unfamiliar with
these newfangled "cable modem" devices, they aren't really modems by
the technical definition, we just call them that because people are
more comfortable that way. And, if you look closely, that big black
wire going into the back doesn't go anywhere near a phone line.

You do get one point, though... I'll grant that his system does APPEAR
to be set up with ICS (although, given the info provided, that's an
ass-umption...it would be odd if he had a computer connected to this
system NOT using it with ICS, so it's probably a safe ass-umption, but
it's still just an ass-umption.)

BUT, if you read the REST of the post, that's not his question, that's
simply his situation...

Read it again if you must...the poster wants to know why, if he has
only two NICs, the second LAN connection is named "Local Area
Connection 3" instead of "Local Area Connection 2". This is evidenced
by the last line of the post that SAYS; "new card became LAC3,..."
This is not a question about ICS, routers or even connectivity, it's a
question about why something is named one thing as opposed to another.

Lastly, "Local Area Connection 2 [3...4...5...whatever]" certainly IS
a naming scheme. That is, this is the pattern that Windows uses to
assign friendly names to connections that are associated with specific
hardware devices. The *NIC* is the device, not the connection.

But, hey, as they say, if you're going to be wrong...be wrong with
*confidence*!

Your vitriolic response eagerly anticipated...
 
Hey fellas, you're speculating - let me clarify the facts

Several posts ago (different thread) I inadvertently used the term
"switch/router" - it was in fact a completely useless "switch" bought on
(wrong) advice from Maplins, since returned and refunded. I have no router,
and my incorrect terminology resulted in incorrect answers, all my fault,
eventually rectified when my error was corrected.

My network is 2 pc's connected via LAN cards. The original card was not
moved or reconfigured since installation (in the slot formerly used by
redundant V92 dial-up modem) and it's connected to my cable modem. Second
LAN card connects via crossover cable to already existing LAN port in a
lap-top.

Internet sharing was indeed set up with ICS.
Network works both as a shared Internet connection (by coincidence, both
pc's are active on-line as I type) and also as a true network - either pc
can see/act on the shared files on the other's HDD.

This post poses a single simple question, born of observation and curiosity.
It wasn't my intention to re-visit earlier posts. It's a new question,
earlier posts are not really relevant to it.

I already knew that XP names the network cards (LAC's) by default, all I
asked was, why did it jump to LAC3, missing out connection 2? I'm not an
expert, just curious. I introduced (and in the very same sentence,
dismissed) the notion that LAC2 may have referred to the original dial-up
modem, no longer present.

I think the answer to the question is essentially in the very first reply.
Nevertheless, I thank you for your interest.

Sincerely, Len.
