Question

I’m trying to load the ActiveDirectory module inside a custom SnapIn that I’m working on. However, when I do so I get the annoying error

“Error initializing default drive: ‘Unable to find a default server
with Active Directory Web Services running.'”

which takes a good 15 seconds or so to timeout. From within a normal PowerShell console I realize you can set a variable to disable the AD: drive mapping but, I cannot seem to get that working from within C# code.

InitialSessionState initial = InitialSessionState.CreateDefault();
initial.Variables.Add(new SessionStateVariableEntry("ADPS_LoadDefaultDrive",
                                                    0, 
                                                    string.Empty));
initial.ImportPSModule(new string[] { "ActiveDirectory" });

using (Runspace runspace = RunspaceFactory.CreateRunspace(initial))
        {
            runspace.Open();
            using (Pipeline p = runspace.CreatePipeline())
            {
                Command getGroup = new Command("Get-ADGroup");
                getGroup.Parameters.Add("Filter", this.Group);
                p.Commands.Add(getGroup);

                var results = p.Invoke();
                this.WriteObject(results, true);
            }
        }

I’ve included what I think should work but, the ADPS_LoadDefaultDrive setting seems to be ignored as each time I try to make a call into the ActiveDirectory module I get the same web services error (along with a painful timeout)

Answer 1

Try to set ADPS_LoadDefaultDrive as an Environment variable, not a regular session variable.
