捕获 RPC 服务器不可用错误 HRESULT：0x800706BA

在 powershell 中，我可以使用 Catch [System.UnauthorizedAccessException] 捕获“访问被拒绝”错误。我如何类似地捕获 RPC Server Unavailable 错误？

如果将公共参数 -ErrorAction Stop 添加到 get-wmiobject 命令（在我的例子中），它将导致该命令将此非终止错误作为终止错误进行响应，并将其丢弃以捕获操作。

这是我用于此目的的代码。我可能应该更具体地说明这一点，但它现在有效。

# Is this machine on network?, if not, move to next machine
If (!(Test-Connection -ComputerName $computerName -Count 1 -Quiet)) { 
  Write-Host "$computerName not on network."
  Continue # Move to next computer
}

# Does the local Administrator account exist? Returns a string if it exists, which is true-ish.
try {

  $filter = "Name='$olduser' AND Domain='$computerName'"
  $account = Get-WmiObject Win32_UserAccount -Filter $filter -ComputerName $computerName -ErrorAction Stop

} catch {

  Write-Warning "$computerName Can't check for accounts, likely RPC server unavailable"
  Continue # Move to next computer

} #end try

If you add the common parameter -ErrorAction Stop to the, in my case, get-wmiobject command it will cause the command to respond to this non-terminating error as a terminating error and drop it to catch for action.

Here is the code I'm using for this purpose. I probably should be more specific in the catch, but it works for now.

# Is this machine on network?, if not, move to next machine
If (!(Test-Connection -ComputerName $computerName -Count 1 -Quiet)) { 
  Write-Host "$computerName not on network."
  Continue # Move to next computer
}

# Does the local Administrator account exist? Returns a string if it exists, which is true-ish.
try {

  $filter = "Name='$olduser' AND Domain='$computerName'"
  $account = Get-WmiObject Win32_UserAccount -Filter $filter -ComputerName $computerName -ErrorAction Stop

} catch {

  Write-Warning "$computerName Can't check for accounts, likely RPC server unavailable"
  Continue # Move to next computer

} #end try
