Powershell Add-NcCifsServer keeps failing - Cannot find an appropriate domain controller

wafl_scan — Wed, 04 Jun 2025 18:18:39 GMT

I'm struggling to understand why I can't create a new CIFS server from Powershell when I can do it from the CLI with the all the same settings no problem. Since I can do it just fine from the CLI I would assume all the DNS and networking settings are correct. Also, I've verfied I'm not making any typos when typing the userid and password for the active directory domain. I even tried creating the computer object in AD before running Add-NcCifsServer but it didn't help. Any help or suggestions would be appreciated! Thanks!

Get-NcVserver $DestinationSVM | Add-NcCifsServer -Name $NewCIFSServerName.ToUpper() -Domain <my FQDN> -AdminUsername $DomainUser -AdminPassword $DomainPass

Hello!

Plaese run 'DCDIAG /testDNS' utility on Your nearest domain controller and check its output for any issue.

It seems to me You have some problems with Your AD.

Thanks for the suggestion. Ran dcdiag /test:dns and everything passed. Everything works fine from the NetApp CLI or with AD in general. It seems that when the Powershell toolkit issues its calls to Active Directory those calls don't seem to be able to get all the information needed. I'm not sure what would be different from doing the same thing in Powershell versus the CLI but there seems to be something different. Thank you.

Hi,

Did you configure and enable DNS on the vserver before performing a cifs setup? EG:

PS C:\> get-help New-NcNetDns

NAME
    New-NcNetDns

SYNOPSIS
    Creates DNS configuration for a vserver.


SYNTAX
    New-NcNetDns [-Domains] <String[]> [[-NameServers] <String[]>] [-State <String>] [-TimeoutSeconds <Int32>] [-Attempts <Int32>] [-IsTldQueryEnabled [<Boolean>]]
    [-IsSourceAddressMatchRequired [<Boolean>]] [-IsPacketQueryMatchRequired [<Boolean>]] [-VserverContext <String>] [-Controller <NcController[]>]
    [-PipelineVariable <String>] [-ZapiRetryCount <Int32>] [<CommonParameters>]
