Hi Pedro,
Thanks for your reply.
This is Robert. Manfred of OOF and I am his backup.
I totally agree with Claus. The problem may be caused by ISP. When the
problem occurs, you can take a cross over cable and attach the laptop
directly to the server's external NIC, try to create VPN, can the issue be
reproduced?
You can send the logs which Manfred quested to v-robeli@xxxxxxxxxxxxx with
subject with subject: VPN disconnection.
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)

<> Hello Pedro,
<>
<> Thank you for posting here.
<>
<> From your post, I understand that you are using SBS VPN and the VPN
<> connection keeps disconnecting.
<>
<> Based on my research, if you installed SP2 on the SBS server without
<> installing the hotfixes, there will be some problems with VPN.
<>
<> Therefore if you installed SP2 on the server, please refer to following
<> article to ensure all the hotfixes are installed.
<>
<> Best practices and known issues when you install Windows Server 2003
<> Service Pack 2 on a Windows Small Business Server 2003-based computer

<>
<> I hope the above information is helpful to you. If the problem still
<> occurs, please help me gather following information:
<>
<> 1. What is the OS installed on the remote clients? Vista or XP?
<>
<> 2. Please help to gather the ISA Info:
<>
<> 1) Download the file from the following URL:
<>
<> http://www.isatools.org/isainfo/ISAInfo.zip
<>
<> 2) Extract all files to a folder on ISA server.
<> 3) Double click Isainfo.js. This will generate 2 files
<> ISAInfo2004-<computer-name>.log and ISAInfo2004-<computer-name>.xml in
the
<> current folder.
<> 4) Please send these files to me at v-mzhuan@xxxxxxxxxxxxx
<>
<> 3. Please also help to gather the ISA logs:
<>
<> 1) Schedule a down time.
<>
<> 2) Open ISA 2004 management console.
<>
<> 3) Expand the server node and highlight 'Monitoring'.
<>
<> 4) In the right pane, switch to the 'Logging' tab, make sure the 'Task
<> Pane' is showed there.
<>
<> 5) In the 'Task Pane', click 'Configure Firewall Logging' under 'Logging
<> Tasks', and then switch the 'log storage format' from 'MSDE database'
<> (default) to 'File'.
<>
<> 6) Switch to the 'Fields' tab, click 'Select All', and then click OK.
<>
<> 7) In the 'Task Pane', click 'Configure Web Proxy Logging' under 'Logging
<> Tasks', and then switch the 'log storage format' from 'MSDE database'
<> (default) to 'File'.
<>
<> 8) Switch to the 'Fields' tab, click 'Select All', and then click OK.
<>
<> 9) Click 'Apply' to save changes and update the configuration.
<>
<> 10) Temporarily disable the Firewall service. To do that, please click
<> Monitoring | Services tab, and then right click 'Microsoft Firewall' to
<> choose 'Stop'.
<>
<> 11) Clear the current existing W3C logs. To do that, go to the log

<>
<> 12) Go back to the ISA 2004 management console, and then Start the

<>
