Load Balancing, Terminal Servers, Virtual IP, Broadcast Pack

[Guest]

Situation:

4 Terminal Servers

Each pair doing virtual IP.

Each sending out a 15k broadcast packet every second. TCP/IP is the protocol being used, so no NetBeui (which uses Broadcast packets).

 

I need to get these 15k packets stopped! How do I do this? Anybody have any documentation?

it's possible you have a chatty nic in one of your servers. disable them one at a time to see if the broadcasts stop.

 

also run an mmc snapin to monitor broadcast traffic and try to determine the mac address of the comp that is sending the packets if the above suggestion doesn't work.

 

how many subnets do you have? do you have a dhcp server on each, or a least a relay agent? check your host id's to make sure you aren't using the basenet or broadcast areas if using non-standard subnets.

 

if all else fails, Clutch is The Man. get hold of him, he is almost a networking god on this forum.

 

let us know how you're doing. good luck.

Better description of problem

 

Got 4 boxes

each pair is clustered

each pair is a terminal server

 

(two pairs)

 

there is one virtual IP that sends users to either pair 1 or pair 2 (Network Load Balancing).

 

Above this virtual IP is a switch. These broadcast packets aren't supposed to get past this switch.. but they are. THAT's what we're trying to figure out.
