CreateProfile

C# Signature:

[DllImport("userenv.dll", SetLastError = true, CharSet = CharSet.Auto)]
    static extern int CreateProfile( [MarshalAs(UnmanagedType.LPWStr)] String pszUserSid, [MarshalAs(UnmanagedType.LPWStr)] String pszUserName, [Out, MarshalAs(UnmanagedType.LPWStr)] System.Text.StringBuilder pszProfilePath, uint cchProfilePath);

Sample Code:

using (System.Security.Principal.WindowsIdentity i = new System.Security.Principal.WindowsIdentity(token))
    {
        System.Text.StringBuilder s= new System.Text.StringBuilder(260);
        uint c= Convert.ToUInt32(s.Capacity);
        int hResult = CreateProfile(i.Owner.Value, username, s, c);
    }

Sample PowerShell Code:

# Attempts to create a profile for the current logged on user.  Obviously, this will not work and it generates a return code 
    # of -2147024809.

Sample PowerShell to lookup Domain User / SID for CreateProfile

$userLogonDomain    = "YourDOMAIN"
    $userSamAccountName = "UserID"
    $domainAccount = $userLogonDomain + "\" + $userSamAccountName
    $strUserSid = ([System.Security.Principal.NTAccount] $domainAccount).Translate([System.Security.Principal.SecurityIdentifier]).Value
    #Create string buffer based on pszProfilePath's 260 char max (picking 240 char)
    $intSizeOfProfilePath = 240
    $ProfilePath = New-Object System.Text.StringBuilder($intSizeOfProfilePath)
    $u::CreateProfile($strUserSid, $userSamAccountName, $ProfilePath, $intSizeOfProfilePath)
