Re: Strange VPN problems

Tech-Archive recommends: Fix windows errors by optimizing your registry



Hi Gene,

Thanks for posting in our newsgroup.

From your description, I know that you can logon the VPN server
successfully but cannot get more information from the server. If I am
off-base, please don't hesitate to let me know.

Please take the following steps to narrow down this issue:

Step 1: The problem may occur after you install the SBS 2003 SP1. SBS 2003
SP1 enables the BootTimeSecurity registry entry. Therefore, after you
install SP1, the Ipnat.sys driver drops VPN packets that it receives.

To solve this problem, please install the hotfix KB 897651. You can contact
CSS to get this hotfix.

For more information, please refer to:
VPN clients can no longer access internal resources after you install
Windows Server 2003 Service Pack 1 on a computer that is running ISA Server
2000
http://support.microsoft.com/kb/897651

If the problem still exists, please provide the following information for
further research.

1. When you visit a share folder on SBS server, what's the error massage?
2. Will the connection disconnect automatically?
3. Can you visit the website hosted on the Server?

I am looking forward to hear from you.

If you need further assistance, please don't hesitate to let me know.


Best regards,

Robert Li(MSFT)
