Re: loss of SOME connectivity

Tech-Archive recommends: Fix windows errors by optimizing your registry

The DNS is the issue - evidently.

The name "local.dcounsel" has always worked just fine - I inherited it.

Similarly, the router has always done the DHCP without difficulty.

Hi Howard,

I'm a little concerned about your Primary DNS suffix and your DHCP.

Normally, a Primary DNS suffix for SBS will be something like:
mydomain.local. Yours appears to be just the reverse (local.dcounsel).

Also, your workstation appears to be in Mixed mode. Normally, SBS 2003
works better if you let it handle DHCP for the LAN and it would use a node
type of Hybrid for the workstations (Type 8).

Is your router handling DHCP for the network?

Typical SBS DHCP setup. Click on Start...Administrative Tools...DHCP.

Address Pool: 192.168.16.0 to 192.168.16.254

006 DNS Servers 192.168.16.2
015 DNS Domain Name yourcompany.local
044 WINS/NBNS Servers 192.168.16.2

As Les points out, if you can browse by IP, but not by name, you are not
getting DNS resolution.

Can be several reasons for this, but sounds like your DNS server is not
communicating with your servers browser. Which is really strange if your
client workstations on the lan are going through your server as they
should,
and they can browse.

Please post the output of the following command from both a workstation
and
the server. There is no reason to disguise anything, but if you must,
you
can change the domain and server names, just be consistent.

open a command prompt (start - run - cmd - ok)
type: ipconfig /all > c:\iptext.txt

copy the output from the server and a workstation into your reply, and
distinguish which is which.

Sorry, I did not read carefully.

They all DO work - in the browser.

Now what?

Thanks for keeping on this.

First, I shold tell you that all the workstation on the network can
browse
the internet without problem. And, I can VNC into the server
without
any
issue. The only issue is that the server cannot send/receive email,
nor
can
it browse the internet.

I Pinged 66.94.234.13 and got the appropriate replies. When I ping
the
same
address with "http://"; in front, I get "Ping request could not find
host .
.
."

I pingd the IP address you supplied for 3COM.com and it worked just
fine.
However, with the "http://"; in front - same result as yahoo.

You're right, I cannot ping microsoft's IP address. And, with the
"http://";
in front, same result as the others.

If the system is a member of the domain you may have to log on to
the
local
system with a local account, preferable the local administrator so
you
can
adjust the IP settings.

or:

Some of the bigger orgs use rotating ip addresses and you can never
be
certain which is the "right" one at the moment.

here is the current (0630 EST) for yahoo.com, which is a place
holder
with
message to put in a name and not a number.

http://66.94.234.13/

try pinging the address as in:

Ping 66.94.234.13

if that works, put it in a browser in this format:

http://66.94.234.13/

does that open?

Try pinging this address, it is for 3COM.com, and it was a valid ip
when
I
tried it.

192.136.34.41

then put it in a browser in this format:

http://192.136.34.41/

you can copy and paste.

Does the site open using the ip number?

if not, what is the exact error on your screen?

and here is www.microsoft.com

ping 207.46.193.254

it will say it is pinging it, but then time out because MS is setup
to
not
respond to pings. But the site should open by ip if they have not
rotated
out of that server by the time you try it.

http://207.46.193.254/

Does any of these sites open using the ip number?

if not, what is the exact error on your screen?

Thanks for the response.

I cannot ping out - Ping could not find host yahoo.com.
The DNS ip address for our ISP are in the correct place in the
router
settings
Yes, I can ping the router, AND the ISP DNS.
Yes, I can open the Linksys management site

I cannot connect the inet cable directly to the server because
the
inet
is
in the basement and I am on floor 2.

MS firewall not started. Linksys firewall in place (always has
been).

I can VNC in AND out.

ICS = ??

Hi Howard:

From the server, if you ping yahoo.com do you get an ip address
followed
by
reply or no reply or time out or?

If you get an ip, can you ping the ip - reply - reply - reply -
reply.

Are the DNS ip addresses for your ISP in the forwarders tab of
DNS
in
Administrative Tools, DNS?
.
