Problem

In Powershell after executing the following command ...

Get-WmiObject Win32_ComputerSystem -Credential second.nl\administrator -ComputerName srv02.second.nl

... the following exception is thrown ...

Get-WmiObject : A security package specific error occurred. (Exception from HRESULT: 0x80070721)

    + CategoryInfo          : InvalidOperation: (:) [Get-WmiObject], COMException
    + FullyQualifiedErrorId : GetWMICOMException,Microsoft.PowerShell.Commands.GetWmiObjectCommand

Scenario

• Server srv01 in AD domain first.nl
• Server srv02 in AD domain second.nl

When srv01 executes the command mentioned earlier. It results in the exception 80070721.

Workaround

Appending the DNS suffix (second.nl used by srv02) in the Advanced TCP/IP Settings on svr01 resolves this problem.

Question(s)

• Why does the WMI query work when appending the DNS suffix second.nl to srv01?
