Unable to connect to SQL server once joined to Windows domain

Hi,

I'm currently building some SQL Server 2014 Enterprise VM's in Azure (using powershell) using the latest SQL server image available.  My issue is that when the VM isn't joined to a Windows domain I am able to connect to SQL server through SSMS (using the local Windows account), however as soon as I join the VM to the Windows domain I am unable to connect to it due to security. If I try and use the previous credentials these also fail.

SQL is configured for Windows authentication only.

My question is, how do I configure SQL server to grant permissions to Windows accounts so that I can access SQL straight away?

I've tried executing the commands below, but they fail.

PS C:\Scripts> Invoke-SqlCmd -Query "CREATE LOGIN [marcus] FROM WINDOWS" -ServerInstance localhost
Invoke-SqlCmd : Login failed for user 'DOMAIN\Marcus'.
At line:1 char:1+ Invoke-SqlCmd -Query "CREATE LOGIN [marcus] FROM WINDOWS" -ServerInst ...+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~+ CategoryInfo          : InvalidOperation: (:) [Invoke-Sqlcmd], SqlException+ FullyQualifiedErrorId : SqlExectionError,Microsoft.SqlServer.Management.PowerShell.GetScriptCommand

Invoke-SqlCmd :

+ Invoke-SqlCmd -Query "CREATE LOGIN [marcus] FROM WINDOWS" -ServerInst ...+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~+ CategoryInfo          : ParserError: (:) [Invoke-Sqlcmd], ParserException+ FullyQualifiedErrorId : ExecutionFailureException,Microsoft.SqlServer.Management.PowerShell.GetScriptCommand

PS SQLSERVER:\>

Checking the SQL error log shows the following:

2014-10-28 11:32:41.72 Logon       Error: 18456, Severity: 14, State: 5.
2014-10-28 11:32:41.72 Logon       Login failed for user 'DOMAIN\Marcus'. Reason: Could not find a login matching the name provided. [CLIENT: <local machine>]

Can anyone point me in the right direction? SQL Server isn't my speciality.
