This post will show you how to build IPsec policy rule using command line on your Windows server 2003.
Lets say we want to block TCP 80 port to make internal web sites inaccessible. First of all we need to create IPsec policy. To do it open command line and type:
netsh ipsec static add policy name=”Block TCP port 80″ description=”Block any internal web sites”
Next step is to create filter for newly created policy. To create it type:
netsh ipsec static add filter filterlist=”80 TCP” srcaddr=any srcport=0 dstaddr=me dstport=80 protocol=tcp mirrored=yes
srcaddr – source address
srcport – source port
dstaddr – destination address
dstport – destination port
Next lets create filter action to block traffic. To do it type:
netsh ipsec static add filteraction name=block action=block
Now we have all needed components to build IPsec policy rule. Policy, filter and filter action. To build policy rule type:
netsh ipsec static add rule name=”Block TCP 80″ policy=”Block TCP port 80″ filterlist=”80 TCP” filteraction=”block”
And the last step is to activate newly created rule. To do it type:
netsh ipsec static set policy name=”Block TCP port 80″ assign=y

This post will show you how to use command line tool powercfg to change power management options. Lets say we need one power-scheme policy for all our portable computers. In this case we will use command line tool powercfg and create bat script which will be distributed to all portable computers users as logon script. Requirements are:
* power-scheme must be set to “Portable/Laptop”
* plugged in monitor turn off – Never
* on battery monitor turn off – 15 min
* plugged in system standby – Never
* on battery system standby – 25 min
* plugged in hard disks turn off – Never
* on battery hard disks turn off – 45 min
To create script open notepad and type:
REM Set power-scheme to Portable/Laptop
powercfg /setactive “portable/laptop”
REM Set plugged in monitor timeout to Never
powercfg /change “portable/laptop” /monitor-timeout-ac 0
REM Set on battery monitor timeout to 15 minutes
powercfg /change “portable/laptop” /monitor-timeout-dc 15
REM Set plugged in system standby to Never
powercfg /change “portable/laptop” /standby-timeout-ac 0
REM Set on battery system standby to 25 minutes
powercfg /change “portable/laptop” /standby-timeout-dc 25
REM Set plugged in hard disks timeout to Never
powercfg /change “portable/laptop” /disk-timeout-ac 0
REM Set on battery hard disks timeout to 45 minutes
powercfg /change “portable/laptop” /disk-timeout-dc 45
Save file as power.bat and distribute to your notebook users as logon script manually or through group policy
