Re: Urgent! New router and big disaster

It's about this time that I like to use Occam's razor.

Turn off all devices except the ADSL modem/router, SBS, and your internal
switch.
Set the 'external' interface of SBS to get it's IP via DHCP from the router
(ensure DHCP on router is enabled, and handing out correct addresses), but
manually point the DNS on the external interface to the 'internal' IP.
Restart SBS. Run CEICW.
Power up 1 workstation, of course, and it will be set to use DHCP currently.
If it gets an IP via DHCP it unnecessary to change to a static config.
If the ws does not get an IP from DHCP check the event log on the server,
also that the DHCP server service is still running.
If all appears OK on the server, but the ws is not getting an IP via DHCP,
set it to manual and configure appropriately.
If you find it necessary to change to a static config, can the ws then ping
sbs, first by name, and if it fails by IP.

If the ws can ping SBS when manually configured that proves that IP/Ethernet
is OK, something else is interfering with DHCP. Check the ws for firewall
programs. These days some AV include firewall features, what AV is in use?

Okay I changed the DNS Server on my nic to that ip of my internal nic and
allowed it to auto get ip from dhcp service (router), No connection to net
from server. so it is now changed back to auto everything from the router,
but these are the only setting in the nic
Even all this, I don't understand why the client machines cant connect to
the server. They can go one day with out internet, but i gotta have them
connect by am.

Yes, the subnet mask can stay the same, it is the subnet which you want
to
change.

If the existing IP is 192.168.1.103/24 (note /24 is just shorthand for
255.255.255.0) and your 'external' interface is 192.168.0.100/24 then
subnets which could be used would be 192.168.X.Y/24 where X is anything
from
2 to 255 (ie. anything but 0 or 1) and Y can be anything you like. I
normally use 2 for Y.

192.168.0.0-255/24 is a subnet.
192.168.1.0-255/24 is a subnet.
192.168.2.0-255/24 is a subnet.
....
192.168.255.0-255/24 is a subnet.

When you run the Change server ip, is it okay to leave the subnet mask
the
same as the external nic? both can be 255.255.255.0? or no? , cuz i'll
try
it
again

Nope, Sorry
did all that and no go... no internet connection from the server. the
only
way for the internet to work on the server is to have the dhcp
services
running on the router. And I dod have it for both internal internet
access
and it also supplies internet to a rental/ conference room. This is
hard
because I also have a static ip from the ISP to put somewhere, and
have
it on
the router.

here is the ipconfig after i made the changes

ipconfig /flushdns : worked
ipconfig /release
All adapters bound to dhcp adressess can not be released
ipconfig/ renew
dchp server can not be found

so that didn't work. I have tried to use the change server ip wizard,
but
either i'm missing a step or it don't work.

Hi Kimmy,

Not sure if Les is online today (I suspect he'll show up sooner or
later),
so:

You have a (2 NICs + router) network setup...

On the router...
Turn off the DHCP service (unless you have a real need for it for
devices that are directly attached to the router, like visiting
laptops
that
you do not want on your SBS network but who need Internet access )

On the external NIC (192.168.0.100) in the SBS server...
DHCP: set to Disabled
IP address: manually assign a static (private) IP address
(192.168.0.100)
Subnet Mask: 255.255.255.0
Default Gateway: set to 192.168.0.1 (the LAN side of the
router)
DNS server to: set to 192.168.1.103 (your SBS server internal
NIC)

On the SBS server...
Re-run CEICW, enable the firewall, make selections and enter your
ISP's
DNS nameservers as "Fowarders" on the appropriate screen (don't use
UPNP
if
it offers, "forward" the required ports manually in the router)

Then on a client workstation(s)... (shouldn't require a reboot, but
wouldn't
hurt after you do these next steps)
ipconfig /flushdns
ipconfig /release
ipconfig /renew
Re-run ipconfig /all to make sure you're picking up a
192.168.1.x
IP
address on the workstation

I'm going on 3 hours sleep and probably getting quite stupid,
I'll
post
the
IP Configs for all in the morning- I gotta get to bed.
Thanks for the quick replys

Don't panic.

Log onto the server desktop, and from a command prompt - run
ipconfig\all
and post the results here. Then get some sleep.

Once the configuration as it is now is known, then it won't be
too
hard
to
get it going again. Folks will be getting up in 5 or 6 hours and
will
be
able to help you. (I'm off to bed now) ;-).

quick brief on orginal setup
Dell Power 1800 server running SBS2003 standard with 2 nics
1 D-link 8 port router & 1- 24 port switch
D-link connected to ISP with a stactic ip and server- onbard
nic
connected
to switch.
Orginal install went off with out a hitch including all
updates
ect.
For
a
week clients could communicate with server.

Yesterday the router dies, and I quickly swapted it with
another
D-link
router this one smaller -only a four port. When the router
died,
other
than
no internet access, the client machines could still connect
to
server.
After I swaped the router everything was still fine.

This morning, I had to go clean up my network room and wires.
During
this
I
shut down the server, and removed of from the room. It was
down
for
about
5
hours.
Then I set it back up, all the same- i didn't touch a
setting,
and
now
my
clients can't login. The administrator can log in client
machines,
release/renew the ip address, look at network places, see the
server
but
cant
connect. No internet access either.

Okay so back at the server -no internet connection but can
see
the
internal
website. The external nic is set to auto get ip from router,
but
the
primary
dns is the ip address of the local nic. When I change that to
the
ip
of
the
router I can get internet on the server. Ran the CEICW...
doh!
The
wizard
poped up with that the router is a plug in play and it wanted
to
configure
it. Now everything is so totally messed.
I cant get any clients to log in but when i set the ip on the
external
nic
back to the router ip, I can reach the remote server login
page
on
my
laptop.
