Hotfix: SCCM 2012 R2 and ADK 8.1 - PXE Boot (WDS) issues

A hotfix has been released recently to resolve WDS (PXE enabled Distribution Point) issues relating to SCCM 2012 R2 and ADK 8.1:
http://support.microsoft.com/kb/2905002

After ADK 8.1 is installed on the SCCM 2012 R2 Site Server (with a PXE enabled DP) there appears to be no issues.  However after a subsequent reboot the WDS service fails to start (Automatic or Manual) and prevents clients from PXE booting.

Furthermore the following application event logs are recorded:
Faulting application name: svchost.exe_WDSServer, version: 6.3.9600.16384, time stamp: 0x5215dfe3
Faulting module name: MSVCR100.dll, version: 10.0.40219.1, time stamp: 0x4d5f034a
Exception code: 0xc0000005
Fault offset: 0x000000000005f61a
Faulting process id: 0xae4
Faulting application start time: 0x01cec5d767184634
Faulting application path: C:\Windows\system32\svchost.exe
Faulting module path: C:\Program Files\Microsoft Configuration Manager\bin\x64\MSVCR100.dll

SCCM 2012 PORTALWEB is not responding to HTTP requests

After installing the Application Catalog in Config Manager 2012 on Windows Server 2008 R2 it is common to see the following error in SMS_PORTALWEB_CONTROL_MANAGER:

Portal Web Site Control Manager detected PORTALWEB is not responding to HTTP requests.  The http status code and text is 500, Internal Server Error.
Possible cause: Internet Information Services (IIS) isn't configured to listen on the ports over which PORTALWEB is configured to communicate.
Solution: Verify that the designated Web Site is configured to use the same ports which PORTALWEB is configured to use.
Possible cause: The designated Web Site is disabled in IIS.
Solution: Verify that the designated Web Site is enabled, and functioning properly.
For more information, refer to Microsoft Knowledge Base.

This issue occurs because the Applicationhost.config file for Windows Process Activation Service (WAS) has the following section defined, and this section is incompatible with the .NET Framework 4.0.

<add name="ServiceModel" type="System.ServiceModel.Activation.HttpModule, System.ServiceModel, Version=3.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" preCondition="managedHandler" />
This section should be defined as follows:
<add name="ServiceModel" type="System.ServiceModel.Activation.HttpModule, System.ServiceModel, Version=3.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" preCondition="managedHandler,runtimeVersionv2.0" />

Note: You can find the Applicationhost.config file in the following location:

%windir%\system32\inetsrv\config

To resolve this issue ASP.NET needs to be registered with .NET Framework 4.0.:

1. Navigate to the following path:
%windir%\Microsoft.NET\Framework\v4.0.30319 (x86 Windows)
OR
%windir%\Microsoft.NET\Framework64\v4.0.30319 (x64 Windows)

2. Run "aspnet_regiis.exe" /iru

Viola! Keep an eye on status manager over the next hour and you will see that this error message will disappear.

Hyper-V Replica Essentials - Book Review

I have recently read a new eBook on Hyper-V Replica named 'Hyper-V Replica Essentials', written by Vangel Krstevski. This Book provides an easy to read fundamental break down of Hyper-V 2012 Replica and its feature set. The book also provides a simple step-by-step on how to install the base components for a Hyper-V Replica environment:

• Installing Hyper-V
• Installing Failover Clustering with Server 2012 shared storage functionality
• Configuring Hyper-V Replica
• Configuring alternate authentication types (Kerberos or SSL Authentication)
• Managing and Administering Hyper-V Replica.

For those of you who would like to get started with Hyper-V 2012 Replica I thoroughly recommend reading this short book.

You can get your hands on a copy of the eBook (PDF, Kindle etc.) by going to Packt Publishing website: http://bit.ly/1aDezz9
