adding a 2ed IP range to SBS 2003

Hi All ,

we have a Sbs2003 server ,been running o 2 years ok , but due to some problem the LAN NIC was replaced with a dul port card. so we splite the network so:-

Internet 192.168.0.X to router & internet
Lan 1 = 192.168.16.x  (with server as 192.168.16.2)
Lan 2 - 192.168.17.x (with card / server  as 192.168.17.2)

so to do a connectcomputer we had to connect them to the x.x.16.x range add them to the server then put them back on the x.x.17.x range

While the network dose work (internet , Map drives, printers all ok ) we can not get to the internet company web page (your IP is on the forbiden list) type error .

BUT also exchange keeps disconnecting and asking for user name & password on   we think ts some thing to do with the new IP range not added to the server in the rigt way .

what we did was dhcp mgr and add another range, point that to 192.168.16.2(server) for gateway,etc then add 192.168.17.2 ....as well

What we would like is a walk thought so as to fine the miss config

Thanks
JA

why did you split the network in the first place? do you see any advantages in splitting the network?

the first part I know exactly where your problem is with the company page.  It is because the original local network was the only network allowed access to the home page, all other IPs are denied access.  I would focus on the Outlook / Exchange problem first.. can we see an ipconfig /all printout from a machine on the 16 and the 17 network?

first off all, the clients must receive their dhcp settings from the sbs server.
an sbs server isn't designed to work with two ip ranges.
you could change this in iis, but this will only corrupt things.
The important thing is, why is there a need for an extra ip range while you could just do fine with a single range.
That way, if sbs is being setup the way it was designed to be setup (via the wizards), things should be fine

Hi all , we setup two range ,just because it seemed the right thing to do .. as the building is in two parts just from an admin side , ,but Iam quite happy to change back , Oh the other reason was the 16.x are on one cat5 LAN & the 17.x are on CAT6 .Nic

All client computer get DHCP from the server Ill logon and get an IPCONFIG later today (not on site at the mo)

so if I read this right  - what your saying is put the 3 NIC in the server setup each an say 192.168.16.2 / 3 / 4 and run the wizard and all should work ?

just put one nic in the server (or two if you are using isa), and make sure you have one ip range, there is no need for a second ip range, even if you have two spererate parts.

Hi all ,

I see what you mean ,what we where looking for is to run 3 x 24port  hubs  each off its own card to keep the speedup (& YES all port are in use on each hub)  1x cat5 2x cat 6 .& one to the internet router .....

hance the IP ranges and the building setup . is this not possible then ?

Ja... Supp is right.  The only reason you could want more than one subnet is if you have more than 254 devices needing an IP address which would really be beyond SBS 2003s capability.  (I know you could have other types of devices that are not dependant upon CALs from Microsoft, but it would still me more traffic than you should have on an SBS network!)  

I think you are confusing subnetting with network segments.  It is possible to have different "branches" of network cabling and gear under the same subnet.  SBS 2003 supports small enough of a network that 1subnet range should be fine.  Good luck!

Cheers,

Brian
