If CA is unavailable, Auditing/ESC6/ESC11 Reporting is Unclear

[jakehildreth]

Describe the Bug
If Locksmith cannot get data from certutil.exe (either from network issues or limited privileges), Locksmith reports Auditing/ESC6/ESC11 Issue as "CA Unavailable" and Fix as "N/A". This is not helpful.

Steps To Reproduce

1. Lock down the use of certutil by low-privileged users.
2. run Locksmith.

Expected Behavior
If CA is unavailable, Locksmith should return the reason why it's unavailable.

Environment

• Locksmith Version: 2025.1.14 (unreleased)
• OS: Windows Server 2019
• PowerShell Version: Windows PowerShell 5.1
• PowerShell Host: VS Code Terminal

I'm struggling with this issue even in a situation where I do have adequate privileges. All the PS Modules are loaded but even with admin level it lists CA Unavailable. Would be nice to get some feedback because every other test I've run between the systems passes.

I'm happy to assist with some troubleshooting or testing too.

Let's add some extra handling to lines that rely on CertUtil. We should capture the command output and proceed based on the strings or error level returned. Some responses that we might be able to handle are:

• Administrator permissions are needed to use the selected options.
• The network path was not found.
• The system can't find the file specified. 0x80070002 (WIN32: 2 ERROR_FILE_NOT_FOUND)
• The network name can't be found. 0x80070043 (WIN32: 67 ERROR_BAD_NET_NAME)
• A connection with the server couldn't be established 0x80072efd (INet: 12029 ERROR_INTERNET_CANNOT_CONNECT)
• The server name or address couldn't be resolved 0x80072ee7 (INet: 12007 ERROR_INTERNET_NAME_NOT_RESOLVED)

And these strings should give us enough info to provide a helpful follow-up in PowerShell.

@MNTech68 are you using Locksmith in a multi-domain forest?

[MNTech68]

No, this is a single domain/forest configuration.

The code requires a 'PING' check before assuming the CA is online. Networks that do not allow ICMP requests will be unable to complete the test suite.

[jakehildreth]

Hi @caractacus! Are you providing a possible answer to @MNTech68 or are you making a request to bypass ping checks?

[caractacus]

An option to skip online checks would be of value to some of our use cases. I’ll try it out. Would you like pull request? Might take some time.
