Wav file with G.723.1 codec can not be played in Windows Media Player of Windows 8

To solve the issue follow the advice on this link:!topic/

"I ended up copying the msg723.acm file from a Windows 2003 Server,  dropped 
it in the \windows\syswow64 directory, then creating a registry entry to the
file under
REG_SZ  msacm.msg723 = msg723.acm .
Now the codec shows up in the Media Player About listing and I can play back 
the call recordings.


Indeed it works much better now.  I have this kind of file generated a voice recording in Altigen MaxACD Call center WAV G.723.1 ((khz, 8bit, Mono, 0.8kb/sec)

the other choice is WAV GSM and WAV PCM. The latter can be played in Media Player out of the box.

Some help for Lync, SFB designers

SFB conversations in mobile and Desktop are different?

MS Project - task types

All is turning around a simple formula:

W =  U * D

where W - work, U - units (number of resources for the task), D - duration.

Task types can be Fixed Work, Fixed Units, Fixed Duration.

Most used is Fixed Work.

If you have 32h of Work and it is fixed, you need 1 person (8h working day) and 4 days then duriation. If you add additonal resource, now you have say 2 persons - then duration will be 2.

Now if you would set task as Fixed Duration and you add second person, MSP will change Work, not duration (because it is fixed). It is less intuitive, but once you have formula and mind and you know which variable is fixed, then all become clear.

Fixed units is also a task type, and guess what - the same formula applies.  Can not change unit then. By changing duration to 2 you will half the work to 16. The same MPS person can only do half of the work if you ask him to half duration.

How to generate packets for testing

The easiest is with Nmaps nping:

 .\nping -c 9999999 --delay 10s --tcp -p 5061 my_testing_host_ip

Take a network trace from SBA without wireshark

SBA is a difficult animal, you do not want to install extra software on it. If you still need to take network trace you can create a following cmd file:

netsh trace start persistent=yes capture=yes maxsize=2048 tracefile=c:\temp\nettrace.etl

timeout 60

netsh trace stop

and run is as administrator

Then open in Microsoft Message Analyser and save as - export as netmon .cap file.

Then you can read it with Wireshark if you want, as you can see it is not possible without Wireshark :)

New-SPContentDatabase creates database with guid instead of name

Hello if you are trying to create a content DB with a name, but instead SP creates name with GUID - make sure that SQL database is deleted from Management studio, but also that files in the disk also deleted (mdf and log). If files will still be there, powershell will not create DB with that name.

Lync monitoring reports - images are missing

After some analysis we found an error in SSRS logs:

reportrendering!ReportServer_0-137!ffc!06/10/2015-12:33:19:: e ERROR: Throwing Microsoft.ReportingServices.ReportProcessing.RenderingObjectModelException: , Microsoft.ReportingServices.ReportProcessing.RenderingObjectModelException: A generic error occurred in GDI+. ---> System.Runtime.InteropServices.ExternalException: A generic error occurred in GDI+.

Apparently gdiplus.dll was not up-to-date on the SQL SSRS server. After Windows 2012 R2 patching the problem was solved.

GetItemById SharePoint list function optimisation

Hello, a little magic for tonight. If you use custom code around your SharePoint, and you wonder why your code is slow on large document libraries , check out this article:

Then search your code to see if you use GetItemById on items collection level. If you do you might accelerate your code 10x times by simply changing it to list level.

Example (red is not optimal code):

SPList _spList = spWeb.Lists.GetList(document.MossDocLibGuid, false);

         ///       SPListItemCollection listItemCollection = _spList.Items;
         ///       SPListItem item = listItemCollection.GetItemById(document.MossDocId);  

SPListItem item = _spList.GetItemById(document.MossDocId);

Visio 2013 - can not replace all words at one go in the diagram

I had an issue with Viso file where I could not edit a word inside a caption string. If you type you word it will delete while string. The same for Find and Replace.

The only way I could do it in bulk is to save as vsdx (xml format), open with 7zip, extract page1.xml, bulk replace in Notepad and inject file back to archive.

Use cache cleanup procedure as described


  • Stop the Windows SharePoint Services Timer service (Found in Windows Services)
  • Navigate to the cache folder
    In Windows Server 2008, the configuration cache is in the following location:
    In Windows Server 2003, the configuration cache is in the following location:
    Drive:\Documents and Settings\All Users\Application Data\Microsoft\SharePoint\Config
    Locate the folder that has the file "Cache.ini"
    (Note: The Application Data folder may be hidden. To view the hidden folder, change the folder options as required)
  • Back up the Cache.ini file.
  • Delete all the XML configuration files in the GUID folder. Do this so that you can verify that the GUID folder is replaced by new XML configuration files when the cache is rebuilt.
  • Note When you empty the configuration cache in the GUID folder, make sure that you do not delete the GUID folder and the Cache.ini file that is located in the GUID folder.
  • Double-click the Cache.ini file.
  • On the Edit menu, click Select All. On the Edit menu, click Delete. Type 1, and then click Save on the File menu. On the File menu, click Exit.
  • Start the Windows SharePoint Services Timer service
  • Note The file system cache is re-created after you perform this procedure. Make sure that you perform this procedure on all servers in the server farm.
  • Make sure that the Cache.ini file in the GUID folder now contains its previous value. For example, make sure that the value of the Cache.ini file is not 1.
