Enable Remote Access to Microsoft SQL Server 2008 R2

In order to enable remote access to Microsoft SQL Server 2008 R2, you will need to open the firewall as stated here:


Also make sure to enable remote access in the SQL Server Management Console, Server options.


Now, in order to access the server via TCP connections to a specific port, you will need to open this port in the firewall and also enable the server to listen on this port in the SQL Server Configuration Manager:

->SQL Server Network configuration

-->Protocols for [InstanceName]

--->Enable TCP/IP and doubleklick the entry. Make sure the dynamic TCP-Port is empty for each IP and set the TCP-Port at the bottom for "All IP's" to your specified port.

You're done.


Office 365 with Exchange online plan 1 and BlackBerry Business Cloud Services works

For all who are unsure if the Office 365 Exchange only plan 1 or 2 do work with the BlackBerry Business Cloud Services, i can clarify that Office 365 "E Plan/Service" "Exchange only plan 1" does work with the BlackBerry Business Cloud Services (you are able to use the BlackBerry Business Cloud Services with this plan).


So you do not need a full E1, E2, E3 or E4 plan to use the Blackberry Business Cloud Services.


REFER transfer not possible with Snom phones and tiptel.comPact 42/82 IP 8 system – call bounces back after transfer

With the tiptel.comPact 42/82 IP system, it may be not possible to transfer calls.


After the transfer initiation, the call may for the caller still be "on hold" and after a few seconds, it bounces back to the original snom phone (3xx).


In order to solve this problem, two settings need to be made in the web configuration under advances->SIP/RTP.

  • Set "refer brackets" on
  • Set "disable blind transfer" on


With these settings, the transfer works.

Change RDP Port on Windows Server 2008 R2

In order to change the Remote Desktop Protocol Port on Windows Server 2008 (R2), please perform these steps:

  1. Open the key "HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\TerminalServer\WinStations\RDP-Tcp" in regedit and search the PortNumber value.
  2. Change the value to your new Port (be sure to do this in decimal mode in the change window)
  3. Save this
  4. Open the firewall for this new port (create a new rule for your new TCP Port)
  5. Restart the Terminal Services service (in German: Remotedesktopdienste)

You will now be disconnected if you are connected via RDP and you will now be able to connect via the new port.

Now you can close the old firewall exception.
