To fix it i added the RD Web Access url to trusted sites in Internet Explorer.

I installed Adobe Reader XI on our Windows Server 2012 R2 RDS servers, and we start to get this error when we started Adobe Reader.

After some time on Google i found out that disabling Adobe Reader XI sandbox protection mode fixed the error.

go to the registry and find this key:
HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Adobe\Acrobat Reader\11.0\FeatureLockDown

Create a new REG_DWORD

Server 2012 “Automatic Maintenance” Killed our SAN

We have had performance issues for a few weeks at night, all our Hyper-V Servers where performing like CRAP every night around 3 AM and for about 45 minutes.

After a long night of investigation with my colleague, we found out that Windows 2012 is running a maintenance job around 03:00 each day.

The Automatic Maintenance window in the Action Center
The Automatic Maintenance window in the Action Center

When we stopped it all began to run as normal. This caused overloading of the SAN SP and gave high disk queue on all servers attached to the SAN.

But, after we disabled the Scheduled Task “Regular Maintenance“, it got enabled Again after some hours.

To avoy this disable “Maintenance Configurator“, but this can´t be done from GUI

To disable Maintenance Configurator run this command on a server with PsExec Link :

psexec \\SERVERNAME -s schtasks /change /tn "\Microsoft\Windows\TaskScheduler\Maintenance Configurator" /DISABLE
Maintenance is now disabled.
Maintenance is now disabled.
