Tony,
Glad you got it working. Believe me, the few issues you ran into are nothing
compare to the mess on an SBS box if you try manually to change things. SBS
is such an integrated beast but if you follow the rules and use the wizards
it's a great product.

Thanks Claus, your procedure worked!
I ran into some problems along the way which I list below with solutions:
Problem: WINS server still had the old IP address
Solution: Updated the WINS server on the NIC setup
Problem: WINS server inaccessible
Solution: Still not sure how I got out of this one but, reset subnet back
to
old setting, found Netbios disabled so enabled it, rebooted server
Problem: Could not see server from workstation and vice-versa, i.e. unable
to ping
Solution: Routeing & Remote Access was blocking connections so disabled,
enabled & reconfigured, ran CEICW
Problem: Could not see workstation from server on My Network Places
Solution: Enabled Client for Microsoft Networks on LAN NIC
By the way, I needed to leave DHCP on the router as my wireless
connections
do not work otherwise.

As with all things in the SBS world, you need to use the wizards.
I your case you need to use the "change the server IP address" wizard
which
will take care of the internal changes like DHCP etc. I would also take
this
opportunity to change the LAN subnet as your current setup can create
problems with VPN connections because 192.168.0.x and 1.x are often used
by
routers as a default and the remote subnet has to be different than your
LAN
for VPN to work.
Here are my suggested steps:
First run the CEICW and switch the 2 NICs and switch the CAT as well (you
will not be able to connect until you are done).
Then run the "change the server IP address" and switch it to something
like
192.168.16.1.
Change the WAN NIC to match your router subnet (0.x)
Rerun the CEICW.
Reboot all workstations so that they receive a valid address in the new
LAN
subnet.
You can rename the NICs to reflect their new role (WAN and LAN).

I am running SBS2003 SP1, routeing & remote access, on a Dell server
with
two
NICs. Internet access is via an ADSL modem/router complete with
firewall.
The
modem/router provides 4 10/100 NICs plus wireless access. I have
wireless
devices which use this capability and are MAC address protected. The
router
uses a static IP address on its internet facing side as we use RWW.
One NIC is the onboard gigabit, while the other is a 10/100 card. When
the
second NIC was added to the server some time ago, the server was
configured
in error with the 10/100 as the LAN NIC and the faster NIC as the
internet
NIC. I now want to take full advantage of the gigabit NIC for the LAN
side
of
things. My problem is how to switch the NIC connections?
I have naively tried using Configure Network Connections from Server
Management to switch the IP config of the two NICs followed by swapping
the
cat5 connectors. The server is no longer visible from the LAN and when
I
try
to run the Connect to the Internet wizard to update network services
etc.
it
will not run and I receive a DHCP error. On checking the IP config of
the
gigabit NIC, it still has the old IP address. There is clearly more to
this
than meets the eye!
Switching back the IP configs using Configure Network Connections takes
me
back to the initial situation with the server visible from the LAN and
the
internet connection working.
The LAN and slower NIC are in the range 192.168.1.x, while the gigabit
NIC
and the 10/100 router LAN ports are in the range 192.168.0.x. My ADSL
port
on
the router is set to my static IP address. DHCP is running on my SBS
server.
I also have DHCP running on my router as I was under the (mistaken?)
impression that this was required to allocate IP addresses to wireless
devices. Looking through other posts I think that the router DHCP
should
be
stopped?
Any suggestions for a procedure to switch the NIC IP configs and cables
would be most appreciated, thanks.
Tony
