Active Directory error "-2147016672"

Question

Hi,
I am creating a script in ASP.NET C# to invoke cmdlets from Lync Server.
I want just list a user : Get-CsUSer and when i run the script i received the follow error code:
Active Directory error "-2147016672" occurred while searching for domain controllers in domain .
I run my script from my local machine developer (it is remote) to the server. The script is :
Runspace remoteRunspace = null;
openRunspace("servidor:5985/wsman", "http://schemas.microsoft.com/powershell/Microsoft.PowerShell",
@"\user", "senha", ref remoteRunspace);
using (PowerShell powershell = PowerShell.Create())
powershell.Runspace = remoteRunspace;
powershell.AddScript("Import-Module Lync"); //funciona
powershell.Invoke();
Pipeline pipeline = remoteRunspace.CreatePipeline();
string remoteScript = "Get-CsUser -Identity mmiranda";
pipeline.Commands.AddScript(remoteScript);
Collection<PSObject> results = pipeline.Invoke();
remoteRunspace.Close();
return results;
public static void openRunspace(string uri, string schema, string username, string livePass, ref Runspace remoteRunspace)
System.Security.SecureString password = new System.Security.SecureString();
foreach (char c in livePass.ToCharArray())
password.AppendChar(c);
PSCredential psc = new PSCredential(username, password);
WSManConnectionInfo rri = new WSManConnectionInfo(new Uri(uri), schema, psc);
//rri.AuthenticationMechanism = AuthenticationMechanism.Default;
//rri.AuthenticationMechanism = AuthenticationMechanism.Kerberos;
//rri.AuthenticationMechanism = AuthenticationMechanism.Basic;
//rri.NoEncryption = true;
rri.ProxyAuthentication = AuthenticationMechanism.Negotiate;
remoteRunspace = RunspaceFactory.CreateRunspace(rri);
remoteRunspace.Open();
i don't know what to do anymore.
Help me.

Hi,gersonczjr
Would you please verify that the user account you used has all the required permission?
Would you please use DCDiag tool to check the DC connectivity?
Although I am not very familar with scripts,I remeber I have seen a similar case with running Get-CsUser using C# is fixed by called
Enable-PsRemoting on ther server,you can try it to see if it also works for you.
