Re: Event 15108 - ISA Server detected a spoof attack..

Hi Dev,

Thanks for your suggestions.

1 - Disable Netbios on external NIC : Already configured that way

2 - File and printer sharing is already disabled. Only TCPIP is selected on
External NIC, and Netmon Network Packet Driver.

3 - Under TCPIP Properties/Advances/DNS tab - the Internal NIC is set to
"Register this connections address in DNS" - How can I check if it's trying
to register with external DNS? (I assume you mean external DNS = ISP DNS
server?)

3b - "Put the external DNS servers to internal DNS forwarders." - I'm not
sure what you mean by this exactly. Are you saying the external (ISP) DNS
servers should be manually entered in to SBS's own DNS records?

Thanks,

Mark

Disable NetBIOS on the External ISA NIC so that it should not register

Uncheck file and printer sharing on the external card
Set the internal NIC to no longer register with any external DNS and
put the external DNS servers to internal DNS forwarders.
Restart all the ISA services.

Error message should stop.. if not lemme know..Will provide you with
some more steps
