[iconbox title=”Work Around” icon=”preferences-system.png” float=”right”][/iconbox]I went to install the LabTech RMM Control Center on my PC to start using LabTech and it kept coming up with “Trial package expired”.

Had to set the PC clock to 20 Nov, 2011 to get the install working! 😉

Once it was done I could set the clock back and keep using it.

A common error that terminal server administrators will bump into every now and then is the “The terminal server has exceeded the maximum number of allowed connections” message.

This problem happens because Windows only allows two remote terminal services connections when you are in administrative mode, and you’ve either got two people already on that server, or more likely, you’ve got a disconnected session that still thinks it is active.

If you happen to be at the same location as the server and can physically log into its console then you this is fine as you can log in and clear the connections. However, things can get a little more annoying if the server is at a remote or client site.
Open a command prompt and type:

mstsc /v: /admin


mstsc /v: /console

Replace “” with your server’s IP Address.

This will connect to the physical console session on the server, thus temporarily getting around the session limit. Please note, however that you may only get one chance at this and if you get disconnected from this session you may have no choice but to physically go to the machine. Therefore, once you get logged in, go straight to Administrative Tools, open Terminal Services Manager and clear those pesky logged sessions! 😉

I had to install a local instance of MediaWiki this afternoon. After setting up a web server, downloading the latest version and completing the installation process all worked well except for the following two lines at the top of the browser:

Notice: A non well formed numeric value encountered in …includesCryptRand.php on line 382
Notice: A non well formed numeric value encountered in …includesCryptRand.php on line 383


Change line 285 from:

$bytes .= $iv;


$buffer .= $iv;

Then I had to logout, clear my cache, then all was fine. I’ll update here if I find out more details about the exact causes of this error/bug.

Apparently, this list has been around for awhile but it’s the first time that I have heard of it. It’s a huge list of Network Monitoring Tools maintained by the Stanford Linear Accelerator Center (SLAC).

This list is exhaustive to say the least, as well as exhausting if you were to go through and investigate every item on the list…

So, here it is: SLAC’s behemoth list of network monitoring tools

Today I needed to capture a screen shot of the Windows 7 UAC prompt for a How-To document I was writing and discovered that you can’t… by default.

Fortunately, there is a registry change that can allow the PrtScn key to work while these prompts are on the screen.

To prevent Windows from switching to Secure Desktop mode when the UAC prompt appears:

  1. Click Start
  2. Enter regedit in the Search box
  3. Navigate to the key: HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionPoliciesSystem
  4. In the right-hand pane, right-click, select New, and then DWORD (32-bit) Value
  5. Enter PromptOnSecureDesktop for the new entry’s name
  6. Right-click your new entry and click Modify
  7. Enter 0 in the Value data box and click OK
  8. Close the Registry Editor

You may have to reboot your system for this change to take effect, although I didn’t today.
