There seems to be an issue with Trend Micro and Windows Defender after Windows/ Defender patches has been applied.
The quick workaround is to deploy are registry key:
The dword value should be 1: DisableAntiSpyware
In case it does not exist, go ahead and create it.
Restart and you should see things start working again.
If you have the issue, you should be able to deploy it using Group Policy Preferences.
NOTE: You can also enter safe mode and create the needed key.
Upgrading your ConfigMgr from Windows Server 2008 R2 to Windows Server 2012 R2 ?
I have had a couple of cases, within the past moth.
.NET seems to break after the OS upgrade.
During some troubleshooting on a not working Application Catalog Web Service Point
- Clients with new software center, did show some applications (but only a few/old from a synchronisation before the upgrade)
- Trying to access Application Catalog Web Site gave an error:
- Cannot Connect to the application server
- No errors in the Application catalog website or service point installation files
So if we dig in to <CMInstallDrive>:\Program FIles\SMS_CCM\CMapplicationCatalogSVC\Logs\ServicePortalWebService.log did show some error:
[11, PID:7048][05/04/2017 12:12:23] :System.TypeLoadException: Could not load type ‘System.Runtime.Diagnostics.ITraceSourceStringProvider’ from assembly ‘System.ServiceModel.Internals, Version=18.104.22.168, Culture=neutral, PublicKeyToken=31bf3856ad364e35’.
The error is related to broken/corrupt .NET
