this week I had the problem on a Windows Server 2008 R2 system that I had to recognize if a network connection to specific closed TCP port is tried to established.
The Windows firewall on the machine is running but logs only packets to the firewall logfile for tcp and udp ports an which a process is listen to. Also the parsing of the logfile is frequently necessary.
A better way is to enable the firewall audit option “Filtering Platform Packet Drop”. This generates an EventLog entry with EventID 5152 for each incoming packet which is dropped. Windows provides the abiltiy to trigger an schedule task after an eventlog entry is written and pass some event details as parameter to a script defined in the task. Unfortunataly not with the GUI.

when it is necessary that normal user needs the ability to do some operations on a service, such as starting or stopping, multiple ways exists to grant these permissions. Windows has no GUI or (easy to use) command line tool on board to set these access rights. I will show you 3 ways to set them.
Sysinternals Process Explorer
sc.exe (Service controller)
subinacl.exe (The security swiss knife)
For the following examples I will use the OpenVPN Service with its Service Name openvpnservice and assign the start and stop permissions to a user or group. But its the same procedure for all other services.
The easiest way is to use the sysinternals Process Explorer. It provides a graphical user interface but has the dependency that the service must be in the running state before process explorer is started. If you already have a valid openvpn configuration start the service:
sc start openvpnservice
Then start the process explorer as administrator and locate the openvpn service process openvpnserv.exe.
you can Windows tell to synchronise your PCs time time with an NTP time server of your choice.
For example the german “Physikalisch-Technische Bundesanstalt (PTB)”, which is the responsible authority of the DCF77 (Time) transmitter, operates three of them:
ptbtime1.ptb.de
ptbtime2.ptb.de
ptbtime3.ptb.de
To set these server as timesource use the following command with Administrator rights:
If the the W32time service does not exists, register them

Now you change the UI from command line language by intlcfg.exe, which is included in the Windows Automated Installation Kit (WAIK) or form the Regional Settings Control Panel intl.cpl.
To installing the language pack by GUI start:
lpksetup.exe
by selecting language lp.cab file.
