Messaging on a LAN

Can anyone suggest a simple way of passing messages between clients on a home LAN. I have a simple LAN in the house using a router with network cards, and two PCS running Windows 98. Broadband is not available here, so to connect to PlusNet , I use Home Highway with a BT USB digital access box on one pc and a terminal adapter on the second pc. It all works brilliantly as of course Home Highway supports two digital lines.

However, there is a risk that both pcs inadvertently are connected to PlusNet at the same time, which of course contravenes the Connect Lite rules. The family therefore has to resort to shouting from one end of the house to the other "Is it OK to connect to the internet ?" Not a sophisticated technical solution, but I suppose it works - until it doesn't !

Ideally, I would like to have a simple pop-up message or other messaging service that could be used to communicate from one pc to the other to ask if it is ok to connect to the internet , and then to notify when the connection has been closed.

Does anyone have a simple solution ?

:?

START >>> RUN and type "cmd"

type "net send <name or IP of machine to send message> <message>"

You can use "*" instead of a computer name or IP address to send to everyone. This is called broadcasting.

Its not recommended you broadcast at work or like we did at College a few weeks back. Our message went to just over 1000 people logged into the network and lets just say they weren't to impressed by my mates slightly offensive message.. including the principal :shock:

Still it was funny and immortalised us in our Colleges history Cool

I guess you could also write a batch file (.bat) with the instructions and message, (1 one with "online" and 1 with "offline") and create shortcuts to these.

Thanks. This sounds just what I wanted, but ............. (there is always a but !)

I cannot make it work !! I am feeble minded but I have tried every trick in the book, so back to basics.

1. If I enter "cmd" under Start>Run, I get the message "cannot find cmd etc". So I presume that "cmd" is short for "command" to take me to DOS.
2. Assuming that 1 above is corret, I have tried entering "net send <*> <test>"
but I just get "file not found".
3. I have tried "net send <169.254.1.2> <test>" but still no luck
4. I have tried using the computer name, but no go."net send \\laptop <test>
5. I have tried all the above both with and without the more than / less than symbols <>

I am obviously doing something stupid. Can you help again please?

I don't think Windows 98 has "net send" you need to use something called winpopup (I think) from the Windows Directory (it has a jack in the box logo on it)

Use winpopup.exe

This is a windows app that allows you to send messages to other users on the network. It must be running all the time to receive messages though.

When you run it select messages->options and tick popup dialog on message receipt.

You don't need to enclose the message with < or > . E.g,
net send MyComputer hello
will work

Hmmm ok so you've already tried that :roll:
I guess it could be the case that net send wasn't in Win98 Sad

Thanks, but I think that is the answer. I have checked net help in dos, and lots of other arguments are included like net view, net use, net start, net stop but there is no net send.

However, the winpopup.exe does admirably and solves the problem for me.

Many thanks to all of you for your help. Smiley

have installed Realpopup on our machines which does exactly what you are asking for - can't remember where I got it from but doubtless a trawl of google would find it

you also have something wrong with your lan DCHP. As any lan IP starting with 169.254 is the default IP range when DCHP fails to work, at a guess your using ICS or the DCHP machine has XP on it.

1. XP - From my routers support forum its been found that XP machines aren't happy with DCHP, its best if using a manually assigned IP for that machine.

2 ICS - I had that problem after changing lan cards in 98se and ICS failed to work with the second lan card even though the first was fully uninstalled if using DCHP only fix was a reinstall of windows as it claimed that the IP ICS required was in use already ie 192.168.0.1
