Get-WmiObject : The RPC server is unavailable. (Exception from HRESULT: 0x800706BA)

Question

When I run

Get-WmiObject win32_SystemEnclosure -Computer hostname | select serialnumber

it works for both local and remote hosts.

Answer 1

I was having the same problem but only with a few machines. I found that using Invoke-Command to run the same command on the remote server worked.

So instead of:

Get-WmiObject win32_SystemEnclosure -ComputerName $hostname -Authentication Negotiate

Use this:

Invoke-Command -ComputerName $hostname -Authentication Negotiate -ScriptBlock {Get-WmiObject win32_SystemEnclosure}

Answer 2

Enabling following FW rules on target system resolved the problem on Win2k16:

• Windows Management Instrumentation (WMI-In)
• Distribiuted Transaction Coordinator (RPC)
• Distribiuted Transaction Coordinator (RPC-EPMAP)

Answer 3

I just came to the exact same issue and found the answer here: http://powershellcommunity.org/Forums/tabid/54/aft/7537/Default.aspx

I had space characters at the end of each line the input file. If your file does too, just remove them and your script should work.

Answer 4

I had same issue, and for me, I was trying to use an IP Address instead of computer name. Just adding this as one more potential solution for people finding this down the road.

Answer 5

Thought I would add that we also ran into this issue with multiple machines in our domain. I created a list of offending machines and added them all to a text file from which to run the script. I ran this from the CMD prompt using elevated privileges.

 psexec @firewallFix.txt -d netsh advfirewall firewall 
        set rule name="Windows Management Instrumentation (WMI-In)" 
        profile=domain new enable=yes profile=domain

Answer 6

Check that the "Windows Management Instrumentation (WMI-In)" rule is enabled in the firewall for each remote machine.

Or in an Administrative Command/Powershell prompt run:

netsh advfirewall firewall set rule group="Windows Management Instrumentation (WMI)" new enable=yes
