dear experts:
I am trying to install a new SBS server to my existing home wirelss network as welll as provide VPN access for 6 laptops and need some help.
hardware overview:
existing:
cable modem: connected to Netgear router. I use dyndns.org service and got a static ip address.
Netgear: WPN824 wireless router configured as DHCP server   ip: 116.118.1.1
Linksys: WRT54G wireless router (ip: 116.118.1.2) configured as router mode with 116.118.1.1 as gateway
I have 3 laptops connect to the netgear wirless router now to get internet access and share print server.

few questions:
1. what's the best topology to configure to setup the network?  2 out of the three laptops will need to access internet only, will not need to connect to the server.
2. Should I use SBS server, Netgear, or Linksys as DHCP router?
3. I can ping the server and the laptop back and forth by ip or name, but I can't get the laptop to join the domain.  I don't think I got the DNS and DHCP configure right.
4. will be any problem providing VPN access to the server with dyndns.org static ip.  

Any pointer to get me start in the right direction will be appreciated.

Thanks!

Chao.

While you can install an SBS into an existing network (http://support.microsoft.com/kb/884453) it is not recommended.  SBS must be the central core of your network, so it's best to build the network around it rather than the other way around.

To answer your questions directly:

1.  For the laptops that only need internet access, don't join them to the domain.  Just use DHCP.  But DHCP should be running from your SBS ONLY.

2.  I think I just answered that.

3.  If the SBS is running DHCP and your laptop is configured to get it's settings automatically, then you should be able to run http://servername/connectcomputer.  You may have to add http://servername to the trusted sites in IE on the laptop.

4.  No problem at all as long as you use your dyndns.com FQDN in the configure remote access wizard.

Is your 116.118.1.x range a typo??? Because that is not a valid Private IP subnet.  You should use 192.168.16.0/24 for your SBS network.

Please see http://sbsurl.com/techguide for all the resource documents you'll need to configure this.  Remember, SBS is a preconfigured server and requires that you follow the prescribed methods to install and configure any further.

thanks for the response..
I took your advise and use the Netgear wireless router as gateway and plan to use it as firewall if possible.
I tried to configued the SBS as DHCP and DNS, but I am having problem connect any laptop, hardware or wireless to the network.  laptops will not get any IP address from the SBS.  If I use Netgear as DHCP, not problem.
I followed the instruction on DHCP setup, but I must done something wrong?
Do I need to do any port forwarding on the Netgear for the laptops to get IP from the SBS?

I was using the 116.118.1.x for existing network.  I now change to 192.168.20.x range

what's does /24 mean behind the IP address?

sorry if the questions sound so simple to you..

I now change the ip range to 192.168.16.x   with netger .16.1  SBS .16.2
I connect the laptop and SBS to the switcher only, it still will not pull IP from SBS
I can ping the laptop by ip and name, but laptop will not ping SBS by ip or name.
The firewall on SBS is not enable.  it seems like something is blocking on the SBS side.

now I can't even get the basic network connection to work :(

No problem with the questions.  if you changed the IP of the server you needed to use the Change Server IP Address wizard (in the Internet & Email section of the Server Management Console).  Please run that wizard and then rerun the Configure Email and Internet Connection Wizard.

Then, please post a current IPCONFIG /ALL from your server as well as from your laptop or a workstation.

P. S.  the /24 means that you are using a 255.255.255.0 subnet.

I use the Change IP address wizard, and then Configure email & internet wizard and still not able to ping the server from the laptop client, but I can ping Netgear no problem.  I still could pull IP from the SBS, so I assign static to the laptop client.

Server Ipconfig/all

Server Ipconfig/all shows
IP: 192.168.16.2
S/M: 255.255.255.0
G/W: 192.168.16.1
DNS: 192.168.16.2
WIN: 192.168.16.2

Laptop Client:  (Static not from SBS DHCP)
IP: 192.168.16.140
S/M: 255.255.255.0
G/W: 192.168.16.1
DNS: 192.168.16.2


I had Linksys as older G router and was having problem with drop signal and goes out, then I pickup a new Netgear mimo G.  I was using Linksys for print server, IP phone, and hardwire laptop, and using Netgear for the wireless connection to 2 other laptops.  
The Linksys actually completely died last night, it won't even power up any more, so I am back to 1 router now.

Thanks!

Chao.

Can you please post a complete IPCONFIG /ALL from both server and client?  Posting just those lines is of little help.

Also, why are you not using DHCP on your laptop?  It looks as though you didn't manually configure all the settings that DHCP would provide.  It doesn't generally make sense to use static IP's.

I used the DHCP on the hardwire connection, but can't pull IP from the server
I prefer use DHCP, I use static on the wireless connection to see if I can ping the server.  I can ping the router fine. and the server can ping the wireless connection address no problem.

Since this become a seperate issue from my initial question.  I will give you another 250 points for this problem I am having.

Thanks!

Did you hand type that IPCONFIG?  You can easily just copy and paste by using the edit functions of the CMD window either by right clicking on the upper left corner of the window, or right clicking on it's task bar button.  Just FYI.

So, this laptop is one of the ones that is not in the domain.. which is fine... but you probably need to do a couple of things to get it to work.  First, disable the wireless connection just to see if you can get the wired connection to take.  Then, do an IPCONFIG /FLUSHDNS followed by an IPCONFIG /REGISTERDNS.  You could also use Windows XP's Network Connection "REPAIR" function as well, which would flush the ARP cache.

Then, make sure that the DHCP Relay is enabled on your router... otherwise it's probably blocking it from the server.

actually this is the one I am trying to join the domain, but since it won't connect, I couldn't join the domain.
to simplefied, I am using a seperate hub to connect the server and workstation.

something weird..  it gave me message on the command screen "unable to conntact your DHCP server.. request time out", but when I do ipconfig/all it pulls an ip from the server.  but I am not able to ping each other by ip address now.

Since I got this server partially loaded... I think I may just complete relaod the server and start from the beginning..

Thanks for your help.

You can't have two network connections enabled when you are joining a computer to the domain.  You MUST use the wired connection and disable the wireless to do that.

What do you mean the server is "partially loaded"?

That could be my initial problem.  I was trying to join the domain using wireless network connection, but I also had my wireless router as my DHCP server.

I purchased the server through 3rd party.  it's new, but when I got it OS was already installed.  After I logged in, it prompted me to insert SBS cds.  
one question, what's best way to reload the SBS and start over again.  Should I completely reformat the HD and start from that point?

Thanks!

Jeff,
just want to thank you for your help.
I reinstalled the SBS and everything seems to working fine now.  The clients are connecting to ther server fine and server is assigning the IP addresses.  
next thing for me will be connecting few clients through VPN.  I may come back with more quetions!
