Please share this video with your friends/co-workers – i believe that discussed problem is very common in our IT community.

Facts about Active Directory to help understand it and properly use.

March 6, 2017 by Munkhtuvshin Baatar

  1. AD is the basement/heart/glue for all Microsoft (and not only Microsoft) server products. Almost any Microsoft solution is based on AD as a prerequisite. Therefore it’s common misunderstanding and misuse that AD is considered only as side effect (or even as lesser unavoidable evil :)) of implementation of other Microsoft systems like MS Dynamics NAV, Exchange, Lync, Sharepoint. It means you cannot install Exchange without pre-installation and pre-configuration of AD. As a result of a such wrong approach to AD many companies don’t use Active Directory appropriately, some of them completely don’t understand what is the main role of AD

iMac and macbooks in Windows environment, why you better integrate them.

The main reason why you need to limit end-users on Windows and Mac computers is the same – much longer periods of stable, guaranteed work with less maintenance overheads.

Recently i see more and more companies which ignores that principle. Mindlessly MacOS is considered as more stable and protected by default without any needs in extra efforts. But if you don’t deprive end-user rights for full system configuration as you do for Windows computers you can get really bad problems. The most unpleasant one is when you got a blocked computer with unknown EFI firmware password. On modern models of

GAL/Global Address List without Exchange

One of the most useful features of Lotus, Exchange and so on is Global Address Directory which can be centrally maintained by IT team or delegated HR user .  GAL makes company email, phone contacts lists more adequate, freshly updated and as result more trustworthy, with less mistakes unlike manually updated on each user Outlook (after regular mass email with updated contacts for everybody in organization. Such multiple updates finally completely mess up all contacts, multiple NDR and returned email)

Advantages of GAL:

  1. new employee immediately has access to the latest updated company contacts
  2. no need manually for each user

Video how to use Monuni v1.0 on one computer for multiple Windows users

It’s highly recommended to avoid assigning to ordinary user excessive rights. A such limitation considerably reduce that workstation maintenance time and efforts, creating more stable and predictable work environment.
But on other hand it’s very common that many sysadmins provide LocalAdmin rights justifying themselves that legacy programs stop working without elevated rights. It’s one of the main reasons when Active Directory implementation projects misstep.

In fact there are several resolutions for a such situations. One example is demonstrated below:

Monuni v1.0 program.

Purpose: to convert old style win1251 encoding text (created by Monkey, Monwin and others) to Unicode text directly … Read the rest

Some considerations about what is highly preferable to have for SMB companies in Mongolia:

1. For central office to have at least small server room – dedicated isolated room with at least consumer Air Conditioner [better japanese – about 1500000 mnt + installation fee]( when you use only RACK without server room – too loud, physically not secure even for locked RACK [anybody can hit or collide with RACK and shock damages hard drives], too much dust which will clog all fans and as consequence rise of temperature, fan speed, even more noise). Size is at least 2×2.5 meter to place RACK and be able to go around it, room door better … Read the rest

pros:
1. considerably cheaper, more affordable
2. small size
3. later can be re-used as usual workstation

cons:
1. not so reliable as a real server
2. weak redundancy
3. not supported by vmware and so on
4. no real RAID, only fake intel matrix raid.
5. not so high quality of internal parts and so on
6. if to compare with Dell PowerEdges – no lifecycle controller, idrac and so on (poor remote management)

But what justifies such compromise approach:
1. i7 cpu is not so good as recent Xeon, but very close by performance (good enough for
