In Windows, it is possible to obtain the MAC address of the wireless access point you're connected to. This is handy when you have multiple access points with the same ESSID (i.e. "roaming") and want to know which one you're connected to. This is done with the netsh CLI tool, available since Windows XP.

To do this, start a command prompt, and type in:

netsh wlan show interfaces

This shows all wireless interfaces on your system. When your wireless is active and connected to an AP, you get output similar to this:

Name : Wireless Network Connection Description : Intel(R) WiFi Link 5100 AGN GUID : f5ad6606-3b9d-41b  ...

When you are running an Exchange server, and have your users access the server from outside the company network, you usually have to open up access to OWA. This enables users to access their mail, contacts and appointments by using an internet browser. Occassionally, someone also has a ActiveSync enabled phone that they would like to use. This protocol also uses OWA for syncing data. And very rarely, there's also a guy (usually the CEO) who simply wants to use its Outlook to connect - this is possible through web as well using RPC-over-HTTP(S), but that's information for another blog post (on another day in the far far future...) .

One of the hassles when configuring this, is the fact that   ...

Once in a while, it may become necessary to update the Blackberry OS to a newer version. I've noticed with the service providers in Belgium that they are usually some versions behind. If whenever you need to run an application that requires a more sane (recent) version of the BB OS, you get stuck because you cannot install and/or run it.

Now you may wonder what the problem is?
Indeed, one can download the latest version from the Blackberry site, but doing so may actually break your setup, as there are quite a few things to consider:

Does your device support the new OS?

Does your service provider support the new OS?

If you are running BES, is it new enough to support the new OS?

Luckily,  ...

Had a problem with a client of ours, running Blackberry Enterprise Manager. One of the devices, a Blackberry 8820, stopped receiving any sync messages. Internet on the device kept working, and the internet e-mail account worked as well, but all communication between the BES and the device failed.

The first thing I did was to completely wipe the device, as I assumed there was a problem with the pairing between the server and the thing. But when I tried to reactivate it, it indefinitely hung on the first phase:

user@domain activating

As I was troubleshooting using the support site of Blackberry (where they explain the steps that occur when activating), I noticed that the activation e-  ...

When you have a working SBS 2008 server, and don't know the password to get into Directory Services Restore Mode, you might want to reset it to something you do know.
You will need this when for instance, the AD gets screwed up, or, in case of SBS, you get locked out (even though you're an Administrator).

Resetting domain password on a SBS 2008

With the installation of the SBS, the DSRM password will be the same as the password you enter for the Administrator account. So, if the password hasn't changed, or you still remember it, try that one first.

You can change the DSRM password by using ntdsutil.

Open up a command prompt, and start ntdsut  ...

If you ever happen to get locked out of a SBS 2008 system, with no way to get back in as Administrator (it's easier than you might think), use the instructions in this blog should get you back up and running.
Note that you will have to have physical access to the server, or else it will be very challenging to solve the problem.
The content of this has been tested for real on an SBS 2008 which had this problem. Check out the bottom of the page for the sources I used to compile this post.

For a background story, read this post.

In order to get in the server, we need some way of an account and password. As the SBS is a domain controller, you can't simply use the local Administrator account...  ...

Microsoft has invented Windows Small Business Server for small to medium businesses. This, in itself, is not a bad idea. It allows small businesses to enjoy the capabilities and functions of a Windows Server with Exchange and more, for a fraction of the price it would be when buying standard editions of the components.

Unfortunately, Microsoft's idea is that small businesses probably don't have IT outsourcing, so they wizard everything up, and basically add a whole bunch of constraints and this-is-how-you-should-do-it's. Although Microsoft isn't all that wrong about this policy, they forgot about the number one rule: less is more.

With SBS 2003, there were already quite a few specially cra  ...

Since Office 2007 (and Vista), TWAIN has been kicked out in favour of WIA. As a result, it is no longer possible to use your favourite and robust TWAIN based scanner with Office 2007.
Most scanners come with the necessary software, and thus, you can circumvent the issue by using their software. However, there are various scanners - notably, office network scanners, like those on copiers, do not have such a tool. They have their driver's internal system which is callable in other software (like Office-applications). In the event that the driver is only supporting TWAIN interface for image acquisition, they do not show up in Vista's scanner list, and therefore, they cannot be used by Office 20  ...

When running a Windows XP or 2003 in VirtualBox, under certain circumstances, the guest may generate a BSOD when booting. The message of the BSOD is a:


It is accompagnied by a referral to processr.sys, intelppm.sys or p3.sys, depending on the CPU used to install the machine.

The reason for this BSOD is a problem with these drivers, trying to perform an unsupported operation inside the virtual machine (like updating microcode or changing the power state of the CPU).
The issue usually surfaces when the guest machine is moved to a different system with different CPU time.

To resolve the issue, the processor drivers have to be disabled. T  ...

We had a bit of trouble with an Apache2 server, configured as a front-end proxy for a IIS running various different sites. The idea for this has grown because of the fact that our client had only one public IP address at the time, but had to run multiple sites. Rather than running the sites in IIS on different ports, we setup the Apache2 to proxy requests to the IIS back-end, so the sites were accessible by means of sub-urls.

http://myserver/mysubdomain1/ -> http://internal-ip:my-port/

For this, we used mod_proxy, and the ProxyPass and ProxyPassReverse.

Lately, our client complained of regular errors when surfing the sites. Apache2 would give HTTP error 502 (Bad gateway) on the page  ...

If you're looking for a better defrag, check out UltraDefrag:

Some highlights of the software (as told on their site):

  • Boot Time Defragmentation allows for defragmenting upon boot (like an antivirus), useful for system files, like the registry, the pagefile, ...
  • Option to shutdown the computer once defrag has completed.
  • Aside of defragging, there's also compacting, which rearranges data to the beginning of the disk, increasing performance and stability;
  • Single file and folder defragmentation, in case you only need to defrag an application or files that have just been placed on disk.

During the course of the lifetime of a Windows Installation, you're bound to stack up on one or more devices that no longer exist. Additionally, some device (existing or not) with an attitude, could very well make your life a living hell.

When you're using a Belgian keyboard (or another) on a Windows 2003 Terminal Server, you might have the same problem we had: characters that are formed with a combination of AltGr and other characters (e.g. the @ sign) don't work as they should.

There are two things you can do to work around this problem.

Instead of using AltGr, try using CTRL+ALT and the key you want. This circumvents the problem, but may not be what you want.

You can change the application of Windows key combinations. Rather than applying them to the TS, you can change it so it applies only to the local computer.
This disables the Alt+Tab and Windows key in the TS session, which is probably also not really what you want  ...

When printing from a Vista computer to a shared computer, you notice the following:

Printing takes a long time to begin.

Opening the Print dialog (e.g. in Word) takes a long time.

Selecting printers in the Print dialog is slow.

The real reason is unknown, but Vista seems to have a problem with excessive querying of the printer. Along with the usual slowdowns of network traffic, this causes serious slowdowns.

The trick is to have Vista believe it is dealing with a local printer, rather than a shared printer. This is done by specifying a Local printer port, pointing to the share, then configure the printer on that port:

Open Printers, and then Server Properties.

Select the Ports tab, an  ...

For all nVIDIA users, I suggest installing the hotfixes recommended by nVIDIA: link.

If you have SLI, first install KB936710 (that's hotfix 2 on the nVIDIA page).

Most importantly, install KB940105 (hotfix 1).

And finally, there are KB938194 (hotfix 3), and KB938979 (hotfix 4).

A Terminal Server can be put in two modes:

execute mode: this is the default mode. In this mode, users can log in the TS and run applications.

install mode: putting a server in this mode will notify the TS of changes in the system when installing software. This is important, because otherwise software would fail to properly get installed, and there would be all kinds of ugliness going on.

In Windows 2003, a server should automatically be put in to install mode if your installation software has setup, or install in their file name. In Windows 2000, you have to put the server in the correct mode, by installing software using Add/remove programs in the Windows control panel. Note that in Win  ...

When running Photoshop CS2 on a Windows 2003 with Terminal Server, regular users cannot start Photoshop CS2. If they try, the following error is displayed:

An error has been detected with a required application library and the product cannot continue. Please reinstall the application

However, when running with Administrator privileges, there is no problem.

CS2 requires the SeCreateGlobalPrivilege privilege. By default, regular domain users don't have this privilege, and thus, CS2 doesn't work.

Assign the required privilege to the users. Normally, assigning this privilege to trusted users should not give any security problems. I do suggest creating a new security group and assign th  ...
