Hi Gregg,

Thanks for the help.
DHCP is "pure". At home it is from the routers at work ir is from the SBS
box.

There are few fixed IP's (3 servers, 2 routers).

IPconfig /release /renew /flush dbs seem to have no effect on the
connectivity.
NSLOOKUP always looks for the SBS as the default gateway.

The wonder of all of this is that it worked without error for 8 moths.
When
I put the server 2003 box on the network seems to have caused these
problems.

I ran gpedit and all the gpo's are "not configured" which is as it should
be.

I currently have a laptop here that is off the domain.
ipconfig /release SUCCESS!
ipconfig /flushdns SUCCESS!
ipconfig /renew SUCCESS!

Connect to Internet...fail!

The client software is Symantec VPN (same as our router/gateway) There are
no settings for "allow remote gateway".
But , again...this worked fine for at least 8 months until the Server 2003
was placed on the network.

Liam,

Are you using pure DHCP both at work and home (NO fixed address
anywhere)?
Make sure you have no fixed IP addresses for DNS servers. You **should**
be
able to use a batch file with "ipconfig /release && ipconfig /renew" in
it
to make it easy for the end users to release/renew the address.

As long as no fixed settings are there, and as long as the user's home
router is configured properly, it should get the correct addressing.

What is the result of taking the laptop off the network, then running
"ipconfig /release" followed by an "ipconfig /all" command? Please post
your
results here.

Do you have any GPOs forcing IP settings?

Crina Li,

Thank you so much for replying and attempting to help me solve my
challenge.

I have done everything you have asked and still remote clients cannot
find
a
dns server other than the Primary Domain Controller on the domain.

I am sure that I need to find a way to "change the default gateway on
the
remote PC"
Since the default gateway is ALWAYS the domain controller of the SBS
domain!
From home this is a real problem.

Hi Liam,

Thank you for posting in SBS newsgroup.

From the description, I understand the issue to be: you want to let
the
laptop can surf internet from home without going through SBS. If I
have
misunderstood your concerns, please do not hesitate to let me know.

As I know, when a laptop which is set to obtain an IP address
automatically
connects to your network, it should contact the SBS server for an IP
address (including DNS and other settings) and then it can browse the
internal network and Internet web sites. When the laptop disconnects
from
the network cable, all IP configuration should be deleted by the
system
automatically.

Currently, we can check the following configuration on laptop:

1. IE setting:

1) Open IE and then Click Internet Options on Tools menu.
2) Click Connections and then click LAN settings.
3) Check if you have selected Automatically detect settings.
4) Please do not use Proxy server to see how thing goes.

2. IP address and DNS settings:

1) Right click My Network Places and select Properties.
2) Open the properties of the Network Connection you are using to
connect
to internet on home.
3) Select TCP/IP and then click Properties.
4) Have you specified the SBS as the DNS server?
5) Make sure you have selected Obtain an IP address automatically and
Obtain DNS server address automatically if you are obtaining the IP
and
DNS
from ISP automatically when you surf internet at home.
6) Click Advanced and then check if you have configured SBS on it.

If you do want release an IP address, you can use the following
command:

ipconfig /release

ipconfig /renew

Hope it helps and I look forward to hearing from you.

Best regards,

Crina Li (MSFT)

| |
| Greetings,
|
| I appreciate any insght into this unusual network case.
|
| SUMMARY
|
| When a client PC is physically removed from the domain it cannot
access
the
| Internet unless the VPN software is running.
|
| SITUATION
|
| When users physically remove their PC's from our domain (they take
them
home
| at night) they are unable to surf the Internet from home.
| The only way for them to connect to the Internet is to use the VPN
client
| software.
| Once they are connected to our Domain, they can surf!
|
| HISTORY
|
| The domain has two locations 20 kilometres apart. They are connected
with
a
| persistent VPN tunnel. For 10 months users can access resources
at/from
both
| sides.
| Users have been able to go home and VPN into the network.
| Users were able to connect to the Internet from home without any
trouble
and
| without using the VPN client software.
| A MS Server 2003 was installed at the remote site as a local data
store.
| Since this has been installed, the users cannot connect to Internet
UNLESS
| the vpn software is running.
|
| SOME TEST RESULTS
|
| PING works from home.
| IPOCONFIG shows a local ip address (from a home router).
| NSLOOKUP always shows the IP address of the main SBS2003 server.
| Hence the need to connect via VPN to get on the Internet.
|
| QUESTION
| How do I get my clients to release the IP address of the main
SBS2003
server
| so that they can surf the net from home?
|
| Thanks for helping,
|
| Liam
