Hi Carlton,
Thanks for posting in our newsgroup.
From your description, I know that the RRAS users cannot obtain IPaddresses from SBS server. If I am off-base, please don¡¯t hesitate to let
me know.
Please let me know the following to make the situation more clearly:
What the topology of the network, do you have a router between the SBS
server and the Internet?
Do all the VPN clients or some of them have the issue?
Do you have ISA server installed?
Please take the following steps to narrow down this issue:
Step 1: Please try to rerun the CEICW wizard, the wizard help us to
configure RRAS security setting, IP Configuration, Remote access ports and
DHCP Relay automatically.
For more information, please refer to:
825763 How to configure Internet access in Windows Small Business Server
2003
http://support.microsoft.com/?id=825763
Step 2: Please Run the Configure Remote Access wizard to configure VPN.
1. Open Server Management select Configure Remote Access.
2. Select to enable remote access and choosoe VPN access or Dial-in access(
require a modem).
2. Input the VPN Server name. You can input IP address or full Internet
domain name of the VPN server.
3. Finish the Wizard.
?
Step 3: On a LAN workstation, can you establish a VPN connection to the
server?
For more information, please refer to:
305550 How to configure a VPN connection to your corporate network in
Windows XP Professional
http://support.microsoft.com/?id=305550
Step4: Please check if GRE Protocol 47 is enabled on your router. GRE
Protocol 47 is used in conjunction with PPTP to create VPNs between clients
or between clients and servers. Refer to the following Knowledge Base
article for more information about GRE Protocol 47:
241251 VPN Tunnels - GRE Protocol 47 Packet Description and Use
http://support.microsoft.com/?kbid=241251
If the problem still exists, please help me collect the following
information for further research:
MPS Report:
a. Visit
http://download.microsoft.com/download/b/b/1/bb139fcb-4aac-4fe5-a579-30b0bd9
15706/MPSRPT_NETWORK.EXE to download the file.
b. Run the MPSRPT_NETWORK.EXE on the server box.
c. Wait for 10~15 minutes.
d. Open Windows explorer, navigate to
%SYSTEMROOT%\MPSReports\Network\Reports\cab\
e. Send the .cab file directly to me at v-robeli@xxxxxxxxxxxxx with
subject: PostReview-38293510-VPN, RRAS & DHCP.
I am looking forward to hear from you.
If you need further assistance, please don¡¯t hesitate to let me know
Best regards,
