Case Study
Event ID
20049 - An invalid request was sent to the admin support thread for Remote
Access Service, possibly from a down level admin tool. The request was not
processed.
Event ID 20073 – “The
following error occurred in the Point to Point Protocol module on port: port
number, UserName: user name. The authentication server did not respond to
authentication requests in a timely fashion”.
VPN
Error 619 - The port was disconnected
Symptoms:
All your Windows 2000 VPN clients connecting to the Windows 2000 VPN server
worked for last a few years. Recently, you upgraded some of Windows 2000
computers to XP. Now upgraded computers can’t establish the VPN and receive
Error 619 - The port was disconnected . All Windows 2000 computers can
establish the VPN without any problem.
2.
After you upgraded the Windows 2000 to 2003, VPN client can’t establish the
VPN with Error 619. The server Event Viewer lists
Event ID: 20049 - "The user connected to
port VPN#-### has been disconnected because the authentication process did
not complete within the required amount of time."
3. You can establish
the VPN internally. However, when you try to access the VPN from the
outside, the VPN client receives Error 619 and the server receives Event ID
20049.
4. The server Event
Viewer may show Event ID 20073 – “The following error occurred in the Point
to Point Protocol module on port: port number, UserName: user name. The
authentication server did not respond to authentication requests in a timely
fashion”.
Analysis: If you receive VPN Error 619, Event
ID 20049 or 20073, this is authentication. In other words, you do have a
good connection.
Possible solutions:
1.
This problem most likely is secure
issue such as unsecured password. So, check
the settings.
2. It could be the hardware issue. Try to re-setup the device or
download the new driver or just reset the devices such as modem and router.
Also make sure GRE IP protocol is open.
3.
Setup the VPN users on Remote
Access Policy of the VPN server rather than dialup permission.
4. If the RRAS is in
a domain network, add the VPN server to the appropriate group. To do this,
go to Active Directory
Users and Computers>domain
name>Users,
double-click the RAS and
IAS Servers security
group. Select the members and add the VPN server to this group. Or use netsh
ras add registeredserver at a command prompt (registeredserver is vpn server
name), and then press ENTER.
5. Make sure you use
correct domain username and password if the VPN server is a member of the
domain.
6.
The RRAS server's authentication
and encryption settings are set to require Microsoft encrypted
authentication and you are using Remote Authentication Dial-In User Service
(RADIUS) as your authentication provider.
7. Both client and
server have different Authentication Methods.
8. On the client
site, make sure the VPN client security setting match the server settings.
9. If you are using
PPTP, you may try to select PPTP on the VPN client. To do that, go to your
VPN Properties>Networking. Change the drop-down box from Automatic to point
to point Tunneling Protocol (PPTP)
