VPN disconnect in one hour and error 800

Postby guest » Wed Jul 23, 2008 4:40 pm

I have a issue with my Windows Server 2003 SP1, RRAS server. It seems that it works great for say 5 minutes to 1 hour, then stops working and I receive the infamous VPN error 800. I have seen alot of posting and was wondering if anyone have ever run across this same problem. I do not understand why it is happening over time, if it work say at 5 to 60 minutes, why shouldn't it just keep working.

Once I get this VPN error 800, that all she wrote, I can not get it to work without doing one of two things.

1) restart the server
2) restart the RRAS server/service.

Any ideas?

- I suggest that we consider the following aspects:

1. Disabling Receive Side Scaling:
=============================
TCP connections are reset when Receive Side Scaling is enabled in Microsoft
Windows Server 2003. This problem occurs if you use Network Address
Translation (NAT), if you use Windows Firewall, or if the host computer is
configured to be an Internet Connection Sharing host server computer.

So please try to disable Receive Side Scaling on the VPN server. To do
this, please follow these steps:
1. Run "regedit" to open registry editor.

2. Locate and then click the following registry subkey:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters

3. On the "Edit" menu, point to "New", click "DWORD" Value, and then type:
EnableRSS.

4. Double-click "EnableRSS", type: 0, and then click "OK" and restart the
server.

For more information about reset TCP connections with Receive Side Scaling
enabled, please refer:
You cannot host TCP connections when Receive Side Scaling is enabled in
Windows Server 2003 with Service Pack 2

2. Does ISP support VPN?
======================
To confirm this, please contact the ISP to determine whether VPN is
supported. We also can try to connect the VPN server from LAN to exclude
the impact of ISP.


3. Updating clients and VPN server:
=============================
Please install the latest updates on the VPN server and clients.


4. Disable all third-party services:
=============================
Some third-party software may cause unexpected result on VPN server, such
as PC Tools. So please try to clean boot the server to see if the problem
is still there.

To clean boot the server:
1. Click "Start"->"Run", type "MSCONFIG" (without quotation marks) and
press ENTER to start the System Configuration Utility.
2. Click the Services tab, check the "Hide All Microsoft Services" box and
click Disable All.
3. Click the Startup tab, click Disable All and click OK.

Can't run any .exe files on DC from member server

Postby guest » Wed Jul 23, 2008 4:43 pm

you cannot run any .exe files on a domain
controller from a member server. If I have misunderstood, please let me
know.

Based on my research, this issue is generally related to security settings
in Internet Explorer. With Internet Explorer Enhanced Security Settings
enabled, running executable file directly over the network or mapped drive
will be disallowed and we may get the following error message: "Windows
cannot access the specified device, path, or file. You may not have the
appropriate permissions to access the item".

I would like to confirm if the symptom you encountered is the same.
Otherwise, please describe in more detail about the symptom of the issue
that you are experiencing.

If so, I suggest we try the following suggestions to troubleshoot the issue:

Method 1:
============
1. Open IE-> and go to Tools Menu
2. Choose Internet Options-> Go to "Security" tab.
3. Choose Internet ->Click on Custom level button.
4. Search for "Launching applications and unsafe files" -> Enable the radio
button "Prompt (recommended)"
5. Repeat the steps 3-4 above for the "Local Intranet" zone.
6. Make sure to close all instances of IE and check if the problem is
fixed.

Method 2:
=========
1. Click Start, click Run, type in "regedit' (without quotation marks) and
press ENTER.
2. Locate the following registry value and make sure its value is set to
0x00000000(0)

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Internet
Settings\Zones\1\1806

3. Locate the following registry value and make sure its value is set to
0x00000000(0)

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet
Settings\Zones\1\1806

4. Quit Registry Editor and try again.

Method 3:
============
1. Click Start, click Run, type in "appwiz.cpl" (without quotation marks)
and press ENTER to open Add/Remove Programs
2. Click "Add/Remove Windows Components", uncheck the item "Internet
Explorer Enhanced Security" if available.
3. Then please test the issue again.
