Q1 - how is ISA configured; single- or multi-network?
Q2 - is ISA acting as a firewall or just a proxy behind SEF?
Q3 - what IP is the ISP quoting when they refer to the broadcasts?
You can stop NetBIOS name broadcasts by adding the following registry
value:
HKLM\System\CurrentControlSet\Services\NetBT\Parameters
Name = NodeType
Type = DWORD
Value = 2
** Note that this setting is also #46 in your DHCP server or scope
options <HINT> **
Additionally, ISA 2004 installations may need to have the following
value:
HKLM\System\CurrentControlSet\Services\Tcpip\Parameters
Name = EnablePMTUDiscovery
Type = DWORD
Value = 1
Both values require a machine reboot to take effect.

Dear All,
I have ISA 2004 and around 150 firewall clients, my Internet suddenly
slowed down and my ISP complains that any of the machines from form
internal network is doing data broadcast which is eating bandwidth. How
do I get to know which machine is doing that can I find from ISA server
or need to opt another way. Please suggest
Sincerely,
Shamshad Ahmad
