Windows Search in Windows 7

I was getting tired of the constant disk activity on my workstation, I have  1.5TB diskspace on it and Windows search seems to enjoy joyriding these disks as if it was surfing on sunny beach..

Anyhow, I figured out how to turn the darn thing off, however that had some dire results – disabling search means COMPLETELY removing all search capabilities, I was stunned after the reboot – F3 did no longer work, Win+F did not work and all search boxes was removed.  Under WinXP disabling Windows search just meant that your search was not indexed, but that is in the past, believe me Windows won’t work without Windows Search..

So my next assignment is to figure out how to minimize the disksurfing, it must be possible..  a lot of my HDD space is stuffed with files that only rarely changes and thus updating the index of these ought not to be nessesary.  If you have any good tips on how to minimize the constant indexing let me know 🙂

Forgotten Windows Password

The issue came up today when a coworker told about his Windows 2000 machine he had at home that he had forgotten the password for, now for corporate use we have the Microsoft ERD commander cd (previously Winternals) which works perfectly..  but that is for corporate use (SA license required)..

Anyhow, I remembered there was some strange utility that could do the same thing, it took a little googeling but I quickly found it it’s;
http://pogostick.net/~pnh/ntpasswd/

Free and all 🙂

Another approach would be, find KonBoot (the first version was free, but it has now gone commercial) it may be a bit hard to find the free version but it is out there and works..  Boot with KonBoot, bypass windows logon (password can be bypassed by leaving the field blank), now create a new admin account (eg call it “admin”)- set password – make this new user member of the local administrators group.  Now boot without KonBoot and login with this new account, you can now change the password for the real administrator account…  (it may also be possible to change the password for the administrator account while booted via KonBoot, but I am not 100% on that)..

I managed to find KonBoot here; http://www.darknet.org.uk/2009/06/kon-boot-reset-windows-linux-passwords/ 

Problemo solved 🙂

Untangle – a cool open source TMG for your lan

, , ,

In these days Internet security is more important than ever, would it not be neat if you could run all your Internet traffic through a big filter to filter out all those nasty viruses, malware and privacy concerns!?   Well, if you happen to have an old PC lying around or as I have a server running MS-Hyper-V then you actually can fairly simple (and free)..

Ok, you may have heard about such solutions as; Smoothwall, monowall and others like them?  These are basically routers/firewalls, and could with a PC (and two nics) replace your broadband router, they contain complex firewall capabilities and maybe even VPN connect possibility.  All very cool and quite easy to setup and use..

Untangle go a step further than this, to the basic router capability is added firewall, vpn, antivirus scanning, privacy filter, ad filter, spam filter, captive page and much much more.  The best part is that most of this is free, you can download a bunch of apps and install these (this is point and click, so no linux knowledge is required).

So how does it work, is it a proxy or is it a gateway or what?  Well once installed you set the LAN nic IP as the default gateway and viola all traffic is now filtered against malware, virus, spam, privacy concerns and what not..

I setup my Untangle box as a Hyper-V machine on my Windows 2008R2 server, gave it 640mb ram and two cpu’s and a 120gb hard drive (of which it is now using aprox 6-7gb).

Once installed you configure everything via the web-interface (not on the box itself if you use Hyper-V, but on you own pc);

So a few notes on installing the app as a hyper-v virtual server;

  • Obvious disadvantages, you will never be able to install the Hyper-V additions into the Linux box, thus no mouse ever which leaves the user interface on the installed box useless.
  • I had to run the installation 4-5 times before I succeded, dont know why it failed but it was as if the installer just stalled during the installation, thus I suggest you take a snapshot once you manage to install the basic system (now you can always revert to here).

Ok, let me just give you the quick tour of installing the thing, it is not a complete guide
(so no screenshots and some obvious steps may be omitted, but if you know a bit of Hyper-v’ing it should not be too hard);

1. Download the Untangled install cd from; http://www.untangle.com/Downloads/Download-ISO

2. Create a new Hyper-V machine (I suggest 640mb ram, 2 cpu’s), replace the NIC with two legacy NIC’s (required to work), an IDE drive – I used a dynamic drive of 120gb but I think performance may be better if you set a static drive of perhaps 20gb, mount the downloaded ISO as the CD rom. Tweaks; you can stick to one legacy NIC if you do not plan to use the box as a firewall (eg. if you have a HW firewall in your ISP router etc), some things will not work with only one nic but most will.

3. Start the system and select the Text based installer (as you have no mouse in hyper-v), I seemed to have better luck with the advanced installer..  You should set static IP’s so decide on two IP’s before getting started.

4. Once the installation is complete switch to your browser and connect to the IP you set as the LAN side during install

5. Take a snapshot of your of your Hyper-V machine.

6. Now download the “open source pack”, on the left of the interface.

7. Configure the different modules, I suggest you disable/turn off the firewall, anti spam, PG, intrusion prevention features (unless you plan on using the device as your main router) as this will speed up performance.

8. Now set the LAN NIC IP as your default gateway on your pc (or on your DHCP server)

You can even set up a captive page, this will require people to have a password in order to access the Internet quite cool – sadly it does not support limiting bandwidth, download ratios etc. but well it’s still cool.

Don’t worry if your first or second install fails, as mentioned I had to do multiple installs before it succeeded, but now it runs fairly smooth.  I have experienced that the web-interface was unavailable (network still worked, but I could not reach the interface), but after a reboot everything was back online.

iReboot for those with dual or tripple boot needs..

iReboot is NeoSmart Technologies’ simple yet effective reboot helper tool. iReboot sits in your taskbar at startup (only taking up 400KB of memory!) and lets you choose which operating system you want to reboot into. Instead of pressing restart, waiting for Windows to shut down, waiting for your BIOS to post, then selecting the operating system you want to boot into (within the bootloader time-limit!); you just select that entry from iReboot and let it do the rest! If you liked EasyBCD, you’ll just love iReboot!

SiteMagic CMS

A new CMS system has entered the scene, SiteMagic CMS..  It exists in three versions; one free (with advertisements), one paid without advertisements (cheap) and one paid without advertisements and with mysql support (the two first are file based which is OK for smaller sites but likely not sufficient for large sites with heavy load).

Check it out at;

Internet Explorer 8 – first run screen

, ,

Are you as annoyed as me in regard to the “first run wizard” thingy that IE8 is displaying the first time it runs?? It’s as annoying as the older IE’s that also launched the Email creation wizard… as if it was not enough that they always start off by launching some stupid intro site..

Anyhow, no reason to get TOO upset, as with most things there are ways around this, so take a look here;
http://digitaljive.wordpress.com/2009/07/23/disable-ie8-%E2%80%9Cset-up-windows-internet-explorer-8%E2%80%9D-wizard/
many lovely ways to get rid of this stupidity.

One of the simplest is this;

Registry:
DWORD : “DisableFirstRunCustomize” set to 1 under HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Main

Troubleshooting ‘At least one service or driver failed during system startup’

You receive the following error message after Windows 2003 boots.

At least one service or driver failed during system startup.  Use Event Viewer to examine the event log for details.

There is a  quite excellent article here on how to debug errors like this; http://networkadminkb.com/kb/Knowledge%20Base/Windows2003/Troubleshooting%20%91At%20least%20one%20service%20or%20driver%20failed%20during%20system%20startup%92.aspx

I found it while trying to find a way to surpress the dialog box, which sadly I did never find (one would think there would be some registry tweak that would disable this stupid dialogbox on a server where the error had no effect and was impossible to resolve)..

W32Time issues on Win2003 server – and resolution

Had problems with a server that was complaining that it could not sync. time with the DC, it stated that it received invalid data amongst other.

Event ID 38, 47 and 29 – Source: W32Time
“The time provider NtpClient cannot reach or is currently receiving invalid time data from NTP_server_IP_Address.”

Found the resolution here;
http://www.chicagotech.net/troubleshooting/eventid47.htm

Basically (this worked for me);

1. Click Start, click Run, type cmd, and then press ENTER.
 
2. At the command prompt, type the following commands in the order that they are given. After you type each command, press ENTER.

• w32tm /config /manualpeerlist:<TIME SERVER IP, EG DC>,0x8 /syncfromflags:MANUAL
• net stop w32time
• net start w32time
• w32tm /resync

a few additional dos commands you may try when debugging w32time;
C:\>net time /querysntp
C:\>w32tm /resync
C:\>w32tm /monitor
