repadmin/syncall - "The target principal name is incorrect" - Windows 2003 Server

2012-01-21T13:05:00.002+01:00

If you face this error :

"The target principal name is incorrect"

While trying to repadmin/syncall from a domain controller to another, follow this procedure :

http://support.microsoft.com/kb/325850

From server1 facing trouble do a :

netdom resetpwd /s:server2 /ud:domain\user /pd:*

Where server2 is a domain controller working properly
Note : restarting the server with "Kerberos Key Distribution" service stopped is essential.
One done if your repsync finished with no error

you can put back the service in automatic.

Chrome / Chromium - Socks Proxy and User Agent

2012-01-20T18:23:00.001+01:00

If you want a special shortcut or command to launch Chrome with a socks proxy (Tor for instance) and a different User-Agent (without playing with the Dev tools incorporated) use the following switches :

--proxy-server and --user-agent

for instance :

--proxy-server="socks5://192.168.186.6:9050" --user-agent="Mozilla/5.0 (compatible; MSIE 8.0; Windows NT 5.1; Trident/4.0; .NET CLR 1.1.4322; .NET CLR 2.0.50727)"

For your special Shortcut :

Chromium Shortcut properties

Check this there : http://whatsmyuseragent.com/

And if you want to send the less data as possible, using DuckDuckGo as Default Search engine and removing all "connected" options such as Phishing, Malware protections, Physical Location Tracking etc...couldn't be bad if you know what you are doing.

One Tor to rule them all (one client for multiple computers)

2012-01-19T00:07:00.001+01:00

If you have multiple computers in your network and can't or don't want to install Tor client on every one, here is the way to allow one Tor client to act as Socks Proxy for other computers :

Edit your torrc (located in %appdata%\tor\ if you are running Windows).
Change the SocksListenAddress to the computer IP :

SocksListenAddress 192.168.186.6

Change the SocksPolicy :

SocksPolicy accept 192.168.186.0/24

Restart tor.
From client computer use :

socks://192.168.186.6:9050 (if your tor is listening on 9050)

(Ensure it's working by checking your public IP)
Et voila ! :) Feel free to share your problems if you faced some

In configuration Tab, Networking, Properties

Just fix your bootloader using :

Copy the update.zip file onto your microSD card.
Once your Nexus One off, hold down the trackball and press the power button.

To allow the Server "MyServer" or "MyServer.MyDomain.Ad" to respond to a DNS CNAME Alias "MyService" or "MyService.MyDomain.Ad" you have to edit the registry :

HKLM\System\CurrentControlSet\Services\Lanmanserver\Parameters and create the value DisableStrictNameChecking (DWORD, value 1).

A reboot is required.
