Fix Cannot get performance counter data

I was receiving management error on my windows 2012 R2 server

 

this is what helped:

1. to rebuild perf registry using elevated CMD enter: lodctr /R
2. re register perf libraries: winmgmt /resyncperf

that is what worked for me.

Firefox 59 disable hardware acceleration

 For some reason Firefox 59 on windows 10 (1709) under parallels started to misbehave and displayed address bar text and background all black.

On some pages the page was inverted with blocks of black and some flickering was noticeable as well.

After some frustration and lots of trial and error I disabled hardware acceleration when available option under Firefox preferences which did the trick.

Windows 10 gray-scale

Windows 10 has option to display everything in gray-scale.

It can be switched on and off by keyboard combination of CTRL + WIN + C key

It is possible to activate it accidentally if you have keyboard with CTRL and Windows key right next to each other since CRTL + C is to copy.

Hope this helps someone else who ends up in the gray-scale world of windows 10.

Outlook 2016 to Exchange 2016 mapi connection problems.

 During my exchange 2010 to exchange 2016 migration I run in to outlook connectivity problem which made it impossible to connect.

There are hundreds of similar issues on google unfortunately none of them solved the problem until I found two solutions on separate blogs and combined them and here is my final fix:

1. Set-MapiVirtualDirectory -identity “exchange2016\mapi (Default Web site)” -IISAuthenticationMethods NTLM
2. this requires editing Autodiscover and EWS virtual directory using IIS server interface on the exchange 2016 server.
   Remove negotiate provider from Windows Authentication.
   

 

References:

1. this is the first blog thanks to which I was able to get outlook 2016 working unfortunately only with exchange cached mode disable.
2. this is the send blog (last post have the solution) which helped me to get outlook 2016 working on the local LAN and behind the firewall as well as with or without using exchange cached mode.
3. In addition you need to have MAPI enabled on the exchange 2016 server which is the default but just in case here is the MS link with instructions.
