Devolutions has come up with a new release of their Remote Desktop Manager: a software tool allowing management of all your remote connections (like VNC, RDP, SSH) and so much more. Its latest version is a vast improvement over their previous stable releases, and is a must-have tool for all ICT employees out there with a lot of remote connections to manage (such as myself).

It comes in two flavours:

The Standard Edition is freeware and houses the majority of the features. It allows the storage to various datasources, including MS Access (containing shared access if you will).

The Enterprise Edition is not free, but has some advanced features, such as password saving to a shared datasource  ...

To set up a Windows PPTP VPN server behind your OpenWRT enabled router, you need to forward the necessary ports and protocols, and install the proper modules.

Finding information about how to do this was a lengthy process. I never actually found the necessary info (although I noticed there are quite a few people which are rather clueless about networking; makes me wonder why they're bothering with OpenWRT in the first place, it's not the easiest firmware out there).
But I've managed to compile the bits and pieces of various sources into a coherent mass. It's not a guide in the literal sense, but will tell you want you need, assuming you do know your way around OpenWRT.

The setup was tested  ...

I've written an article before on how to change the outgoing SMTP port for SmartHost in Exchange 2003. Now, I have to do this again for Exchange 2007 as they've changed this procedure.

When you're unable to send e-mail directly to the internet (using MX), you probably have to set up a SmartHost to relay the e-mail for you. This is basically your ISP's SMTP server, but can be another server as well.
In certain cases, the default SMTP port (port 25) cannot be used to connect to the SmartHost, so you have to change this to something else. Gmail for instance, uses port 587 for SMTP. Other 3rd party mail services use this (or another port) as well to circumvent spam protection initiated by a lot  ...

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.

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.

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  ...
