Keine Videotelefonie mehr mit Skype Endgeräten Kommentare deaktiviert für Keine Videotelefonie mehr mit Skype Endgeräten

Seinerzeit habe ich über das Skype Telefon von ASUS (SV1T) berichtet und war prinzipiell sehr begeistert. Kürzlich musste ich leider feststellen, dass kein Video mehr angezeigt wird.

Nach einer kleinen Analyse stellte sich heraus, dass die Ursache eine Inkompatibilität der Video-Codecs ist. Alle Skype-Software-Produkte(Windows, Mac, iPhone etc.) haben einen neuen Videocodec verpasst bekommen. Dieser Codec ist nicht mehr kompatibel zum ASUS SV1T. Lediglich ältere Skype Versionen (z.B. die Version für Windows) sind noch kompatibel.

Ich hatte Kontakt mit Skype (per Chat), die haben das Problem zu ASUS abgeschoben. Der ASUS Support zeigt mit dem Finger auf Microsoft (die haben Skype übernommen). Die Leidtragenden sind die Endkunden.

Soweit ich erfahren habe, sind auch Produkte von Logitech betroffen. Man muss also derzeit sehr vorsichtig sein, welche Skype-Hardware man sich kauft, um nicht mit diesem Problem konfrontiert zu werden.

Es wäre interessant ein wenig Feedback zu bekommen, welche Geräte ihr einsetzt und ob sie funktionieren. Ich könnte mir vorstellen, dass auch Fernseher mit integriertem Skype-Client so ihre Probleme haben werden.

Mit einem Firmware-Update scheint es nicht getan zu sein, da der ASUS-Support mir berichtete, dass die alte Software OpenSource war und Microsoft es nicht zulässt, weiterhin OpenSource in Verbindung mit Skype einzusetzen, deshalb ist vmtl. auch die Android-Version von Skype von diesem Videoproblem betroffen.

Remote Assistance with Windows Kommentare deaktiviert für Remote Assistance with Windows

Since Windows 7 there is a small utility included with the OS called „Windows Remote Assistance“. If you enable it, someone from another machine can execute

msra /offerra

enter your IP address or hostname and can then view and optionally use your desktop (both see everything). Behind the scenes the Microsoft RDP protocol is used which is very stable and performant.

If you are on a domain network your system administrator can enable the Remote Assistance feature on the entire domain, so every user can support another user on demand. What a nice feature! There is no longer a need for 3rd party Remote Control Software to be placed on the clients in your domain, just use what the operating system provides.

The prerequisites are:

Connecting Computer

  • Remote Assistance allowed (e.g. via Group Policy or manually)
  • Microsoft® Windows® Vista or higher

Target Computer

  • Remote Assistance allowed (e.g. via Group Policy or manually)
  • Microsoft® Windows® XP or higher (including Server products)
  • Computer reachable via TCP/IP on port 3389

When offering Remote Assistance to a terminal server (e.g. Server 2008R2) the connecting computer (the guy who wants to help) gets a drop-down list of all users on the server and can select the one who needs help. In this case you can individually support users also on large terminal server installations! To also be able to offer Remote Assistance from the Terminalserver to other users you have to install the „Remote Assistance“ Feature on the server.

As you can see here, it is very easy!




One small problem is the file transfer feature. It has been removed by Microsoft since Windows 7. See the following list:

File Transfer option with Remote Assistance

Windows® XP –> Windows® XX
Filetransfer works

Windows Vista –> Windows® XX
Filetransfer works

Windows® 7 or higher –> Windows® XX
File transfer is no longer implemented

ShowHotCorner for Server 2012 and Windows 8 Kommentare deaktiviert für ShowHotCorner for Server 2012 and Windows 8

At work I recently started to use Server 2012 as a service platform. I am in general not a friend of the new Microsoft Metro UI but I had to deal with it. One problem I immediately run across was how to access the „Run Dialog“ to quickly startup programs.

As I found out, you have to point your mouse to the bottom left corner, the so called „Hot Corner“, then right-click on it to get some of the useful administrative tools like the run dialog or an administrative CMD prompt. No big deal and easy to remember. Btw. If you are directly working on the machine Win + X brings up this menu immediately but Win+X does not work in a Remote Desktop Session.

The only problem I had using the hot corner was that I use a Remote Desktop Manager to access all the machines I maintain and I do not work in full screen all the time. When trying to access the „Hot Corner“ I always moved the mouse out of the Remote Desktop Window and after about 10x doing so I thought about a solution.

At the beginning it tried it with AutoHotKey and attempted to emulate Win+X but it seems, Microsoft interrupts somehow the usage of the Windows key on the newer operating systems.
Then I created a small executable with my favourite scripting language AutoIT that does automatically move the mouse to the bottom left corner, activates the „Hot Corner“ and right-clicks for me. I gave it a wonderful icon that fits very nice into the new Server 2012 UI, pinned it to the taskbar and moved it left most.

Now I can just click on this button and immediately the Win+X menu appears. As an administrator it helps me a lot to do my daily work faster.

Feel free to download this tool called „ShowHotCorner“. It comes with the source code and also pre-compiled x86/x64 versions.

Watch the video below to see the installation process and the tool in action.
