One thing to try - albeit it requires the help from your IT - is to quit and rejoin the domain. 

Hi Sasi

Do your computer have access to the environment's domain controllers?

To just get started quickly, you can try creating a local account (with admin rights) on your computer, and log in to Episerver using that.

Hi Stefan,

Thank you for your response.

I have no idea about your question. And as suggested I created a local account with admin rights, but still getting the same error.

What could be the reason for this issue? It is blocking my development activities.

Please suggest..!!

Hi Sasi

This error message stated that the trust relationship between the workstation and the primary domain failed. You'll need your IT people help you solve this issue. Meanwhile, you can swith to use SQL membership on your local environment to continue your development activities. 

I'm not sure which CMS version do you currently use. The follow instruction assumes you're using membership not asp.net identity

1. Take a look in web.config->membership section, change defaultProvider to SqlServerMembershipProvider

    <membership defaultProvider="MultiplexingMembershipProvider" userIsOnlineTimeWindow="10" hashAlgorithmType="HMACSHA512">
      <providers>
        <clear />
        <add name="MultiplexingMembershipProvider" type="EPiServer.Security.MultiplexingMembershipProvider, EPiServer.Framework.AspNet" provider1="SqlServerMembershipProvider" provider2="WindowsMembershipProvider" />
        <add name="WindowsMembershipProvider" type="EPiServer.Security.WindowsMembershipProvider, EPiServer.Cms.AspNet" deletePrefix="BUILTIN\" searchByEmail="true" />
        <add name="SqlServerMembershipProvider" type="System.Web.Providers.DefaultMembershipProvider, System.Web.Providers, Version=2.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" connectionStringName="EPiServerDB" enablePasswordRetrieval="false" enablePasswordReset="true" requiresQuestionAndAnswer="false" requiresUniqueEmail="false" maxInvalidPasswordAttempts="5" minRequiredPasswordLength="6" minRequiredNonalphanumericCharacters="0" passwordAttemptWindow="10" applicationName="/" />
      </providers>
    </membership>

2. Using the follow initialization code to create an admin user in your database

[InitializableModule]
[ModuleDependency(typeof(EPiServer.Web.InitializationModule))]
public class CreateAdminUserForMembershipInitiialization : IInitializableModule
    {
        private static readonly ILog Log = LogManager.GetLogger(typeof(CreateAdminUserForMembershipInitiialization));

        public void Initialize(InitializationEngine context)
        {
#if DEBUG
            var mu = Membership.GetUser("EpiSQLAdmin");

            if (mu != null) return;

            try
            {
                Membership.CreateUser("EpiSQLAdmin", "6hEthU", "EpiSQLAdmin@site.com");

                try
                {
                    this.EnsureRoleExists("WebEditors");
                    this.EnsureRoleExists("WebAdmins");

                    Roles.AddUserToRoles("EpiSQLAdmin", new[] { "WebAdmins", "WebEditors" });
                }
                catch (ProviderException pe)
                {
                    Log.Error(pe);
                }
            }
            catch (MembershipCreateUserException mcue)
            {
                Log.Error(mcue);
            }
#endif
        }

        public void Uninitialize(InitializationEngine context)
        {
        }

        private void EnsureRoleExists(string roleName)
        {
            if (Roles.RoleExists(roleName)) return;

            try
            {
                Roles.CreateRole(roleName);
            }
            catch (ProviderException pe)
            {
                Log.Error(pe);
            }
        }
    }
