Can anyone here please assist me in resetting the global:DefaultVIServer and global:DefaultVIServers system variables into $null ?

because I cannot do anything with my PowerShell anymore even after reinstalling the PowerCLi and upgrading it into 5.1U2, here's the output of the version information and the configuration information:

Scope    ProxyPolicy    DefaultVIServerMode InvalidCertificateAction DisplayDeprecationWarnings WebOperationTimeoutSeconds
-----    -----------    ------------------- ------------------------ -------------------------- --------------------------
Session  UseSystemProxy Multiple            Unset                    True                       300                      
User     UseSystemProxy Multiple                                                                                         
AllUsers                Single                                                                                           
WARNING: Error initializing default drive: 'Unable to find a default server with Active Directory Web Services running.'.

PowerCLI Version
----------------
   VMware vSphere PowerCLI 5.1 Release 2 build 1012425
---------------
Snapin Versions
---------------
   VMWare AutoDeploy PowerCLI Component 5.1 build 768137
   VMWare ImageBuilder PowerCLI Component 5.1 build 768137

   VMware VDS PowerCLI Component 5.1 build 1012428
   VMware vSphere PowerCLI Component 5.1 build 1012428

Due to this error, I cannot even issue a simple PowerCLi command to get the list of my VM, see the following error:

WARNING: Error initializing default drive: 'Unable to find a default server with Active Directory Web Services running.'.
Get-VM : You have  modified the global:DefaultVIServer and global:DefaultVIServers system variables. This is not allowed. Please reset them to $null and reconnect to the vSphere server.

Any help would be greatly appreciated.

Thanks

I'm not exactly sure how you set those in the first place but you can remove the variables (rather than null them) using the following.

1) First check what you have with in a fresh PowerCLI session with Get-Variable (you should see something like this but likely a value for a server)

Name                           Value
----                           -----
global:DefaultVIServer         
global:DefaultVIServers        {}

2) Remove each using Remove-Variable DefaultVIServer and Remove-Variable DefaultVIServers 3) Try connecting to the correct vCenter with Connect-VIServer yourvcenter.domain.com*

If you keep having variables reset, it's possible you've customized something in the startup file (C:\Program Files (x86)\VMware\Infrastructure\vSphere PowerCLI\Scripts\Initialize-PowerCLIEnvironment.ps1) so you might need to replace/remove the entries there (never tried that, just taking a guess)

PS. Sorry about formatting messs, still getting used to the format

  • Hi Evan, thanks for the reply, I can see there are two variables that I have removed as per your suggestion using Remove-Variable global:DefaultVIServer Remove-Variable global:DefaultVIServers however, it is still the same issue persist. – Senior Systems Engineer Apr 16 '13 at 06:37
