Error 1747: The Authentication Service is Unknown


Do not ask me why, my notebook Windows 7 64-bit woke up this morning bothering me with this error

Windows Could not start the Windows Event Log service on Local Computer.
Error 1747: The authentication service is unknown.

I will not even attempt to look for explanations, not worth it. The solution to so, at least in my case, was to follow the steps below:

  • Go to the Start Menu, type cmd and right click or (Ctrl + Shift and hit Enter), and select “Run As Administrator”.

  • Type the following commands, each followed by pressing enter.

ipconfig /flushdns

nbtstat -R

nbtstat -RR

netsh int reset all

netsh int ip reset

netsh winsock reset

netsh interface tcp set global autotuninglevel=disabled

Top 10 HR Interview Questions & How To Answer Them


Tell me about yourself.

Answer: Identify some of your main attributes and memorise them. Describe your qualifications, career history and range of skills, emphasising those skills relevant to the job on offer.

What have your achievements been to date?

A. Select an achievement that is work-related and fairly recent. Identify the skills you used in the achievement and quantify the benefit it had to the company. For example, ‘my greatest achievement has been to design and implement a new sales ledger system, bringing it in ahead of time and improving our debtors’ position significantly, saving the company £50,000 a month in interest’.

Are you happy with your career-to-date?

A: This HR interview question is really about your self-esteem, confidence and career aspirations. The answer must be ‘yes’, followed by a brief explanation as to what it is about your career so far that’s made you happy. If you have hit a career plateau, or you feel you are moving too slowly, then you must qualify your answer.

What is the most difficult situation you have had to face and how did you tackle it?

A: The purpose of this HR interview question is to find out what your definition of difficult is and whether you can show a logical approach to problem solving. In order to show yourself in a positive light, select a difficult work situation which was not caused by you and which can be quickly explained in a few sentences. Explain how you defined the problem, what the options were, why you selected the one you did and what the outcome was. Always end on a positive note.

What do you like about your present job?

A: This is a straightforward HR interview question. All you have to do is make sure that your ‘likes’ correspond to the skills required for the job on offer. Be enthusiastic; describe your job as interesting and diverse but do not overdo it – after all, you are looking to leave.

What do you dislike about your present job?

A: Be cautious with this answer to this HR interview question. Do not be too specific as you may draw attention to weaknesses that will leave you open to further problems. One approach is to choose a characteristic of your present company, such as its size or slow decision-making processes etc. Give your answer with the air of someone who takes problems and frustrations in your stride as part of the job.

 What are your strengths?

A: This is one HR interview question that you know you are going to get so there is no excuse for being unprepared. Concentrate on discussing your main strengths. List three or four proficiencies e.g. your ability to learn quickly, determination to succeed, positive attitude, your ability to relate to people and achieve a common goal. You may be asked to give examples of the above so be prepared.

What is your greatest weakness?

A: Do not say you have none in response to this HR interview question- this will lead to further problems. You have two options – use a professed weakness such as a lack of experience (not ability) on your part in an area that is not vital for the job.

The second option is to describe a personal or professional weakness that could also be considered to be strength and the steps you have taken to combat it. An example would be: “I know my team think I’m too demanding at times – I tend to drive them pretty hard but I’m getting much better at using the carrot and not the stick”.

Why do you want to leave your current employer?

A: in response to this HR interview question state how you are looking for a new challenge, more responsibility, experience and a change of environment. Do not be negative in your reasons for leaving. It is rarely appropriate to cite salary as your primary motivator.

Why have you applied for this particular job?

A: Through this HR interview question the employer is looking for evidence that the job suits you, fits in with your general aptitudes, coincides with your long-term goals and involves doing things you enjoy.  Make sure you have a good understanding of the role and the organisation, and describe the attributes of the organisation that interest you most.

What is a difference between Kernel Mode and User Mode?


A processor in a computer running Windows has two different modes: user mode and kernel mode. The processor switches between the two modes depending on what type of code is running on the processor. Applications run in user mode, and core operating system components run in kernel mode. While many drivers run in kernel mode, some drivers may run in user mode.

When you start a user-mode application, Windows creates a process for the application. The process provides the application with a private virtual address space and a private handle table. Because an application’s virtual address space is private, one application cannot alter data that belongs to another application. Each application runs in isolation, and if an application crashes, the crash is limited to that one application. Other applications and the operating system are not affected by the crash.

In addition to being private, the virtual address space of a user-mode application is limited. A processor running in user mode cannot access virtual addresses that are reserved for the operating system. Limiting the virtual address space of a user-mode application prevents the application from altering, and possibly damaging, critical operating system data.

All code that runs in kernel mode shares a single virtual address space. This means that a kernel-mode driver is not isolated from other drivers and the operating system itself. If a kernel-mode driver accidentally writes to the wrong virtual address, data that belongs to the operating system or another driver could be compromised. If a kernel-mode driver crashes, the entire operating system crashes.

This diagram illustrates communication between user-mode and kernel-mode components.
