"Windows firewall cannot run because another program or service is

SBS 2003 with 2 Nics gives this error when trying to see if a firewall is
running.

"Windows firewall cannot run because another program or service is running
that might use the network address translation component" (Ipnat.sys)

So the question is: If NAT is running is there a firewall of any sort being
provided?
And a second ? is: Why would there be no positive Google hits for this
error from any official Micosoft support site?

RRAS is providing NAT and firewall services. (Unless this is Premium
with ISA).

Hello,

Thank you for posting here.

According to your description, I understand that:

You have a concern about the error "Windows firewall cannot run because
another program or service is running that might use the network address
translation component" (Ipnat.sys)" when trying to enable the Windows
Firewall service on the SBS 2003 server.

If I have misunderstood the problem, please don't hesitate to let me know.

Explanations:
=============
Yes, you have 2 NICs scenarios that the NAT is enabled on the SBS 2003
server external NIC in RRAS (or ISA). The NAT driver (Ipnat.sys) provides
the network address translation function. It is used by RRAS and Windows
Firewall (or ICS). However, once you enable the NAT in the RRAS, the
Ipnat.sys will be occupied and Windows Firewall cannot start properly. That
explains the error message " Windows firewall cannot run because another
program or service is running that might use the network address
translation component" (Ipnat.sys)".


Hope this helps. Also, if you have any questions or concerns, please do not
hesitate to let me know.



Best regards,
Miles Li

The question is:
If NAT is running is there a firewall of any sort being
provided?
Several replies all skirt answering the question. I just want to know if I
have a server that is protected if I'm using 2 Nics...and ran the IECW wizard
and configured the nics accordingly. If NAT is running, does it provide any
firewalling.
Much appreciation to all replies...skirted or otherwise.

Thanks...so I can assume that there is firewall protection. How can I verify
this with Server Manager on SBS 2003. I cannot find any references to
firewalling there...
Sorry if I don't take your word for it, but since I get the error that
"firewall cannot run" I am rather cautious.
thx..

Thanks...but my question is simply...is there any firewall protection when
using NAT? I'm still not sure. Am I being paranoid? Sorry.
thx....

Hi,

If you are having two nics in the server, you have the basic NAT/Firewall
running. In the RRAS mmc you can see that.
The Windows Firewall Service should never run on SBS and is by default set
to disabled. So the Windows Firewall icon in the Control Panel will not work
and give you the error.
If you only have one nic in the server, you will have to use a hardware
firewall.
