net send over vlans

Posted on 2004-08-23
Last Modified: 2012-06-27

I have just setup my VLANS on the internal network with DHCP and cisco router however .....

1. net send computername msg gives me ...
                An error occurred while sending a message to GUIMARAES .
                The message alias could not be found on the network.

2. Is this a vlan problem or is it  because of net sending across subnets. Either way what is the solution seeing as we utilize net send quite a bit ......

Can you ping the PC name? I suspect not. Can you ping it by IP?

This could be a VLAN problem if you can't ping the IP but if you can, I would look at DNS or WINS for the issue and not net send.

netsend is a broadcast,, which of course cannot cross VLANs,,,, since VLANs sole purpose is to break up broadcast domains.

Hmm..... I have come across this issue, I can ping Ip addresses, I can ping names when i setup wins... this only thing i can't do is login to domain server on different vlans and can't broadcase msgs over vlans. The problem did not happen on vlans. Vlan is fine as long as you can ping over vlans.

Try this, My entire network worked smoothly after I applied the patches for Microsoft software.

Download DS Client for windows 98, nt/xp. from microsoft web sites.. or you can download from my yahoo. www.geocities.com/ggohg

hope this help. :))

I can ping by name and by IP. I should not need the ds client because all of my WS are either 2000 pro or XP.
I agree with mikeleebrla however there must be a way to enable some broadcasts ! ? :(

Is the Messenger Service running on these machines?

If you remove them from VLANs entirely, do they work?

messenger is activated. machines on the same vlan will receive messages as long as net send * is done. if net send is used with machinename or username it fails with the above message!!

While AD relies on DNS, you might need NetBIOS/WINS for NET SEND to work.

Does net send to the IP work?

After some re-configuring .....

From a server which is not on any vlan ....

   net send IP(or)netbiosname is OK
   net send * mess - only sends to machines not on vlans ...

The solution I eventualy ended up with was to create a script that would list computers that were currently logged in and then send a net send one by one, taking into account that net send * is a broadcast and vlans are designed to avoid them.

Thanks for your input
