After upgrading the Operatin System to Windows Server 2012 R2., the 'Altiris Object Host Service' (AtrsHost.exe) continually crashes.

In the client's Symantec Management Agent logs: 'Failed to create remoting request service: name='AtrsHost'.


System.TypeLoadException: Could not load type 'System.Runtime.Diagnostics.ITraceSourceStringProvider' from assembly 'System.ServiceModel.Internals, Version=, Culture=neutral, PublicKeyToken=31bf3856ad364e35'


Part of the upgrade to Windows server 2012 R2 is including .NET 4.5, however the call is looking for a .NET 4.0 library that was previously being used. 

For example:


ITMS 7.6, 8.0, 8.1, 8.5
.NET 4.5, 4.5.1


This issue can be resolved by installing .NET 4.5.2 ( or later.

Then restart the server.
(With newer versions of .NET being available, you may also choose to install a newer supported version of the .NET Framework, ie. 4.6. Please refer to supported .NET versions in our ITMS Support Matrix)
