Hi Allen,
Thank you for posting in SBS newsgroup.
From the description, I understand the issue to be: some client computerscan not obtain IP from SBS server. If I have misunderstood your concerns,
please do not hesitate to let me know.
You may try removing the computer from Domain and then rejoin it to the
domain in client computer. To do that, please perform the following steps:
1. In client computer, right-click My Computer and then select Properties.
2. In Computer Name tab, click Change and the change the computer from
Domain to Workgroup.
3. Reboot the machine.
4. Log on as a local administrator account.
5. In client computer, open IE and run http://servername/connectcomputer.
6. Follow the wizard to finish.
If it still occurs, the most possible of this is the Windows XP SP2
firewall or third-party firewall program block the DHCP traffic.
At the current stage, it is most possible a client side issue of Windows
XP; however, since you have join it to SBS domain and the Windows XP SP2
firewall may be controlled by Group Policy of SBS server, I would like to
help you troubleshoot in this newsgroup.
Before we start troubleshooting, I would like you to double check that the
other workstations in the SBS network could receive IP address by DHCP
service on the SBS serve so that we can confirm the DHCP service is
functioning well. Then, to troubleshoot this issue, I would like to suggest
you following steps.
1. On the Windows XP SP2 workstation, please uninstall any third-party
antivirus and firewall program.
2. On the Windows XP SP2 workstation, please disable the Windows XP SP2
Windows Firewall.
However, if you find the Windows Firewall is enabled and with options
grayed out (cannot be disabled), you may need following process to
configure the SBS server group policy for Windows XP SP2 firewall.
Generally, you could try to edit the ' Small Business Server Windows
Firewall' to enable or disable the firewall on client. However, before the
operation, you need to confirm the following things first.
After you install the Windows XP SP2 in your SBS 2k3 network, you may need
to install the Update for SBS 2k3 server first, please refer to the
following article.
872769 You cannot configure Windows Firewall settings or Security Center
http://support.microsoft.com/?id=872769
If you want to modify the Group Policy setting that is configured when you
installed the Windows Small Business Server 2003 Update for Windows XP SP2,
install the hotfix on the SBS server that is described in the following
Microsoft Knowledge Base article:
842933 "The following entry in the [strings] section is too long and has
been truncated" error message when you edit or view Group Policy in Windows
Server 2003, in Windows XP, or in Windows 2000
http://support.microsoft.com/default.aspx?kbid=842933
After installing the above 2 hotfixes, please use the following steps to
edit the GPO
1. Start -> Administrative Tools -> Group Policy Management.
2. Expand Domains -> Your Domain.
3. Right click the Small Business Server Windows Firewall and click Edit.
4. Computer configuration>Administrative templates>Network>Network
connections> Windows Firewall> Domain Profile.
5. In "Windows Firewall: Protect all network connections" should be set to
'Disable'.
6. Run Gpupdate /force on your XP2 client.
7. Logon and logoff your client and test your issue again.
The following image may help you to configure it.
http://www.sbslinks.com/XPsp2.htm
After disable the XP SP2 firewall, please try to IPconfig /release and
/renew again to see if this issue is resolved.
For managing the Windows XP SP2 firewall under SBS network, you may also
need the following article
Windows XP Service Pack 2 and Windows Small Business Server
http://www.microsoft.com/technet/prodtechnol/sbs/2003/deploy/sbs_xpsp2.mspx
If the issue still occurs, please try to configure the client computer
manually as following:
1. Right click My Network Places and select Properties.
2. Right click Local Area Connection and select Properties.
3. On General tab, high light TCP/IP and then select Properties.
4. Select Use the following IP address and input an IP and set internal IP
of SBS as default gateway.
5. Set internal IP of SBS as DNS server.
6. Try to see if it works.
Also I provide the following general steps to configure SBS and client
computers:
On SBS:
1. Leave the Default Gateway of the internal NIC blank.
2. Configure both the internal NIC and the external NIC to use the internal
DNS Service as the DNS Server.
3. On the DNS Server, create the DNS Forwarder to forward the external DNS
resolution requests to the ISP's DNS server. See:
323380 How to configure DNS for Internet access in Windows Server 2003
http://support.microsoft.com/?id=323380
4. Strictly followed the instructions in the KB article below to run CEICW:
825763 How to configure Internet access in Windows Small Business Server
2003
http://support.microsoft.com/?id=825763
Then, you can bring all the computers from "workgroup" to "Domain" as
following:
1. Make sure the client computers get the IP addresses and DNS
configurations from the SBS 2003 DHCP service correctly
2. In Server computer, Create a user account and computer account for each
user by using the Add Users and Computers Wizard
3. Log on a client workstation using its local administrator account
4. In client computer, open IE and run http://servername/connectcomputer
5. Follow the wizard to finish.
If you have any questions or concerns related to this issue, please let me
know.
I appreciate your time and look forward to hearing from you.
Best regards,

| All of a sudden out of nowhere I'm having problems with some clients not
| being able to obtain an DHCP lease from the server. At first I had
thought
| that maybe it was a hub issue as I do have two of them and clients are
| plugged into either or. But I reloved that by taking a bad client and
| switching hubs with same results. I only have 1 DHCP server on my
network.
| When I go to the bad clients workstations and do an ipconfig /all here's
is
| what is returned.
|
| I get IP's that are on a 169.254.xx.xx network with a subnet mask of
| 255.255.0.0. I cannot do an ipconfig /release and obviously cannot do a
| renew. I've tried restarting the DHCP client service on the workstations.
| Does not help. I can input "static" 192.168.16.xx (my internal network
IP)
| and no problem. However it appears that when I do this those clients
cannot
| access http://companyweb. Help!!!
