AD domain connexion issue

Running a pretty small LAN here with a few servers.

All the sudden we have one of them (2012R2 member server, hosting an SQL instance, but probably irrelevant) acting up

logging as local admin I can ping both our DNS servers and domain controllers... Not exactly sure what is going on.

What set of diagnostic can I run to trace this ?

Alex

Looks like it's fallen off the domain

Test-ComputerSecureChannel -Repair -Credential (Get-Credential)

Open in new window

Give that a shot and see how it goes.

Alex

The above is completely incorrect and has no relevance for the issue you're facing, it's not a domain controller, you're not having issues with sysvol and is completely wrong.

Please don't carry that out.

Noted.

Any suggestion as of what I can test past the ping of both domain DNS and DC ?

Did you run the powershell code?

I did

Windows PowerShell
Copyright (C) 2014 Microsoft Corporation. All rights reserved.

PS C:\Windows\system32> Test-ComputerSecureChannel -Repair -Credential (Get-Credential)

cmdlet Get-Credential at command pipeline position 1
Supply values for the following parameters:
Credential
True
PS C:\Windows\system32>

Open in new window

Login in the domain is possible on an on / off basis. Very strange.

Is there any tool like DCDIAG that would test a standalone machine good standing in a domain

When exactly do you see your error message?
Is that the only symptom that something is wrong?

Please post output from ipconfig /all

Well I went the "hard way" and left the re-joined the domain. All seems ok now.

Alex

Yeah,

It was odd because the Test-ComputerSecureChannel should have done exactly that. Nevermind as long as it works :-)

Have a great weekend.

Thanks
