Re: Loosing Internet Connection

After I removed the RV042 I used the Netopia as a DSL router not a bridge.
After doing this I experienced the same behavior. What gets me is as I
mentioned in my original post that if I changed a workstations DNS to point
to a public DNS i.e. AT&T, Verizon, etc.) I have Internet access on that
particular machine, thus indicating that the DSL connection is still present.
This is why I started to think that perhaps the problem layed on the
server??? Especially since after I ran the Internet/Mail wizard on the
server it starts to work again??? So, if not the server and I still have
internet access what can it be?

Based on the configuration you posted, it appears as though your server has
a private address (192.168.1.91 is not a public IP.) So I have to conclude
that your Linksys device is obtaining the public IP and functioning as a NAT
device as well as a firewall.

So, actually, both my question AND my observation would still apply:

1) How did you remove the Linksys device without breaking your network since
it apparently holds the public IP?
2) The Linksys, holding the public IP, would respond to any external pings
you send, not your server. Thus, your ping results being flaky point to a
problem outside of the server. Linksys, DSL gateway, cables, or ISP. But
not your server.

As for the other questions regarding the DSL connectivity, hopefuly this
will help clear some questions up. There's a Netopia DSL Modem/Reouter
set
up in bridge mode connected with a Linksys RV042 DSL Router/Firewall.
The
LAN ip is static to 192.168.1.1 and the WAN IP is obtained from the PPOE
connection. And yes the PPOE WAN IP is a static address.The services are
then fowarded accordingly via the RV042 to the server. i.e. Service SMTP
on
port 25 is fowarded to the server and so on...

I agree with SteveB and Marina that you should address all issues....BUT,
I
suspect this isn't your problem.

first, as already asked, an ipconfig /all on your server would be
helpful.
Secondly, you mention that your DSL gateway is bridging, so we will
assume,
for the moment that it doesn't hold an external IP address. If this
assumption is wrong, please speak up!

You said you are using the linksys as a firewall/router. Does this mean
it
has an external IP? And if so, does the server also have an external IP?
Or is it configured with a private IP via NAT? Of course your ipconfig
will answer this question, but with either answer I'll have to admit some
confusion which I will explain now, so that you can perhaps provide an
answer along with your ipconfig.

If your linksys is runing in a NAT configuration, how did you remove it
without breaking your entire network? For this to work, you'd need some
head unit holding at least one external IP and routing for you to verify
that the problem persisted.

Alternatively, if your device holds an external IP and your SBS server is
confgured to utilize a NAT address then your ping test should NOT have
pointed to the server as a problem. The server would not respond to a
ping
on the external address. If pings were timing out and then returned on
their
own, you can most assuredly start looking at the network structure
(cable,
devices, software) of everything between the linksys (INCLUDNG the
Linksys)
and the internet...as that is the device that should have been responding
to
the ping....

Hope that helps you narrow your search,

-Cliff

As Marina says you should take action on this and any other issues the
BPA
flags.

SteveB

Thanks for the response.
Currently we are running SBS 2003 SE. After I ran the SBS BPA I
received
warnings on a second NIC wich is disabled, so I'm ignoring this for
now.

One thing that caught my eye was:
EDNS is Enabled:
EDNS is enabled on this server. Some of the routers or firewalls may
not
support EDNS. You should disable EDNS on this server. To do so, click
Start,
and then click Command Prompt. In the Command Prompt window, type
dnscmd
/Config /EnableEdnsProbes 0 and then restart the DNS Server service.

Is this a problem? Should I perform the recommended task?

Not a good idea. Only the SBS IP address should be in the DNS setting
for
both workstations and the server-no external ISP DNS IPs.

Ralph is this SBS SE or PE (with ISA 2004 installed) and 1 or 2 NICs.
Is
SBS
2003 SP1 fully installed and then have you installed Windows 2003
SP2?

Run the SBS BPA to see if it shows any problems that should be
corrected.

add an additional DNS entry on the server as that of the one you
said
you
used on a workstation.
Also include that additional DNS entry gets broadcasted out to the
client
workstations.

We have been experiencing problem with the Internet connection for
the
past
month & I just don't know what to do anymore.

Our Environment consists of a Windows Small Business Server and
the
set
up
is really straight forward. The Server is responsible for DHCP so
all of
the
clients have the same settings. The DNS is the Server's IP and
the
default
gateway is the router. The DSL Router (Netopia) is set up in
bridge
mode
with a Linksys RV042 being used as a firewall/router.

The behavior is strange??? For some reason after a few days or a
week or
so
no one can get to the internet nor do we receive any e-mails. I
know
for
a
fact that the DSL connection is still good because if I run the
Internet/e-Mail connection wizard on the Server everything starts
working
once again. Also, if I change the DNS entry on a workstation to
be
that
of
an ISP (i.e. AT&T, Verizon, etc.) I have Internet access on that
particular
machine.

Sometimes when I ping the external IP I get request timed out, but
after
a
few minutes I start receiving replies??? So at this point
everything is
pointing to the Server? I think???

Below is a list of things which I have done in troubleshooting
this
problem:

1 - I removed the RV042 from the set up but the problem still
persisted.
2 - I have made sure that the DSL line has the needed filters.
3 - I changed the Servers patch cable and changed it to a
different
port
on
the LAN switch.
4 - I have updated the Server's NIC drivers.
5 - I have checked the Event Viewer but nothing is being
registered
here.

Any help regarding this issue is greatly appreciated.

Thanks,
Ralph
