Hi all,

when running an inventory against client machines (Windows 7) spiceworks fails to connect, stating that either no ports were open or there was a failure to connect to the WMI service. I’ve checked the article here and applied the suggested fix, plus any other suggestions i found in help articles, but it still will not connect. I’ve now resorted to disabling the Windows firewall, client AV and almost all non-essential components, also running the Unknown Assistant which states it should be able to connect - but it doesn’t. We’re using an AD domain (2012R2). all client machines are windows 7 X64

the attach screenshot shows a client machine that we’re troubleshooting + attempts to fix

Any ideas what might be causing it to fail??

Hey Sam,

It looks like local WMI is working properly, but there might be an issue with remote WMI.

Please try running the remote WMI commands in the article below from the computer where Spiceworks is installed:

If the commands return an error (example: “The RPC Server is unavailable”) then there is a network or permissions issue preventing remote WMI from responding. The first thing I’d check in this case is DNS. Remote WMI relies heavily on forward and reverse DNS lookups matching. You can test forward and reverse DNS by running the commands below from the computer where Spiceworks is installed:

  • nslookup HOSTNAME
  • nslookup IPADDRESS

(where IPADDRESS AND HOSTNAME are the ip and hostname of the device you’re having trouble scanning)

Hope this helps!

p.s - let us know what you find!

Hi Austex

thanks for the response.

nslookup works for both forward and reverse queries, but still getting 'The RPC Server is unavailable’.

The account I’m using to query the machine is a domain administrator

anything else we could try?

Try turning off UAC:
