We use the following to log Remote Desktop Logons.  If you substitute 3389 with 1723  (PPTP VPN port 1723) it should log your VPN connections.

Add the lines below to each users logon and log off script to create a log file. It would give you UserName, ComputerName, date and time, in a simple single line, followed by the IP from which they connected, if needed. If you wish to know logoff times as well, you can add the same lines to a log off script in group policy (if you don't already have one: User Configuration | Windows settings | Scripts | Logoff). You likely won’t need the last line (IP address) in the log off script.

As written below it will create the log/text file in \\Server\Logs\LogOns.Log and the entries will look like:
Log File

Log On:  jdoe SERVER1  Tue 1/1/2007   9:01
  TCP    10.0.1.100:3389        66.66.123.123:1234        ESTABLISHED

Log Off: jdoe SERVER1  Tue 1/1/2007   9:31

Log On:  jsmith SERVER2  Tue 1/1/2007   11:00
  TCP    10.0.1.200:3389        66.66.123.124:1234        ESTABLISHED

Log Off: jsmith SERVER1  Tue 1/1/2007   11:30
---------------------------------------------------------------------------

:Logging
If Exist "\\Server\Logs\LogOns.Log" GoTo START
Echo Log File > "\\Server\Logs\LogOns.Log"
:START
Echo. >> "\\Server\Logs\LogOns.Log"
Echo Log On:  %USERNAME% %COMPUTERNAME%  %Date:~0,16%  %Time:~0,5% >> "\\Server\Logs\LogOns.Log"
netstat  -an  |find  "3389"  |find  /I  "established"  >> "\\Server\Logs\LogOns.Log"

---------------------------------------------------------------------------
Note the users will need to have read/write and execute permissions for the \\Server\Logs\LogOns.Log  file.

Thanks! I guess that will also work, but there is nothing simpler than that?
Windows Server doesn't keep records/logs/events when users logging in with VPN ?

It does, but it is actually much more complex.  You can enable detailed auditing, and within the configuration, you can configure the systems and successful and/or failed events you wish to audit. Following articles outline how to enable and analyze the results:

However using auditing can be time consuming to filter and extract as the logs become very large very quickly.
