ERROR 629: You have been disconnected from the computer you dialed.

After researching the problem, I noticed that these users after connecting
to the ISP could not ping any external sites like www.yahoo.com.
By doing a
ROUTE PRINT I discovered that they were missing the usual first line
of a
valid ROUTE PRINT output like below
Address Mask
Gateway
Interface
Metric
0.0.0.0 0.0.0.0
123.456.789.123 123.456.789.123
1
This initial address is the default route for any network not specified
in
the route table. Thus the Internet connection doesn't exist.
They are only
connected to the ISP's network. VPN cannot occur because it does
not know
how to get to the VPN server. Add the 0.0.0.0 line back into
the route
table pointing to their assigned IP and whamo VPN no problemo.
Now I have just got to figure out why the default route for external
networks is getting dropped!
Error 629: You have been disconnected from the computer you dialed.

If you try to (re)install the 128-bit version of the Windows 98 Dial-Up Networking Security Upgrade (Msnt128.exe) file, you are unable to do so. When you double-click the Msnt128.exe file, you receive the 128 bit encryption for Dial-Up Networking (Not for Export) dialog box. When you click OK, you quit the Msnt128.exe program.
This is caused because Windows 98 Second Edition includes a newer version of the 40-bit DUN files that replace the 128-bit DUN files.
You can get a new 128-bit DUN Security Upgrade for Windows 98 Second Edition when Microsoft makes it available. To see if the 128-bit DUN Security Upgrade for Windows 98 Second Edition is available, view the following Microsoft Web site:
http://support.microsoft.com/Support/NTServer/128Eula.asp
Note that after accepting the License Agreement, the list of 128-bit software is available.
