    Skype for Business Server 2015

Note

Before you apply this article, make sure that you don't have update 3169706 installed on the affected system.

Symptoms

After you install the February 2017 cumulative update (KB3061064) on a server that's running Microsoft Skype for Business Server 2015 CU4 or a later version, you can't connect to remote PowerShell or run any Skype for Business cmdlets through remote PowerShell.

When this problem occurs, you may receive the following error message:

PS C:\Windows\system32> $session = New-PSSession -ConnectionUri "https:///OcsPowershell" -Credential
$credential -SessionOption $sessionOption
New-PSSession : [<ServerName>] Connecting to remote server <ServerName> failed with the following error message: The SSL connection cannot be established. Verify that the service on the remote host is properly configured to listen for HTTPS requests. Consult the logs and documentation for the WS-Management service running on the destination, most commonly IIS or WinRM. If the destination is the WinRM service, run the following command on the destination to analyze and configure the WinRM service: "winrm quickconfig -transport: https". For more information, see the about_Remote_Troubleshooting Help topic.

Additionally, if you run the Skype for Business Server 2015 Deployment Wizard, you notice the following status for steps 1 and 2 in the installation:

  • Step 1 (Install or Update Skype for Business Server System) is shown as Partial.
  • Step 2 (Setup or Remove Skype for Business Server Components) is not shown as Complete.

If you run the Enable-CSReplica command in the Skype for Business Server 2015 Management Shell, you notice the following error entry:

Error: An error occurred: "System.MissingMethodException" "Method not found: 'Void System.Runtime.InteropServices.Marshal.StructureToPtr(!!0, IntPtr, Boolean)'."
WARNING: Detailed results can be found at C:\Users\seguim02admin\AppData\Local\Temp\Enable-CSReplica-[2017_03_16][15_15_56].html".Command execution failed: Method not found: 'Void System.Runtime.InteropServices.Marshal.StructureToPtr(!!0, IntPtr, Boolean)'.
