Hi Guys,
   Is there any utility to spy on WinPopup messages being sent around the LAN?  Somehow peek at them then let them continue on.

Also, is there a way to stop incomming popup messages?  I've stopped it once but I can't remember how to do it again.
I'm using NT4 sp6.

Many Thanks
Woody.

you can use any network sniffer with a promiscuous network driver to spy on the messages...

to stop it locally, disable the local messaging service.

Whats the best tool for this job?  Free or shareware preferable.

Cheers
Woody.

you'll first need a ndis driver (winpcap)
looks like the netgroup server is down...

here's a mirror
http://www.datanerds.net/~mike/netgroup-serv.polito.it/winpcap/


once you have that downloaded and installed, you can use any number of windows-based sniffers

  - windump also available from the same mirror

IT, Stop Being Called Into Every Meeting

Highfive is so simple that setting up every meeting room takes just minutes and every employee will be able to start or join a call from any room with ease. Never be called into a meeting just to get it started again. This is how video conferencing should work!

They all seem very complex to use.  I just need to view the Winpopup messages that are being sent around the LAN.

yeah, you'll get a lot of garbage with a sniffer...
you should be able to set a filter so that you're only monitoring traffic on the nbt ports 135-139...(i think the sequence goes udp 137 for a lookup and then tcp 139 for the actual message...but i could be wrong)...

I've tried peeking at the packets as they come in but I can't see the text in there anywhere.

Thanks for the help.  Didn't manage to do it in the end but I did learn some other cool stuff.

Thanks
Woody.
