Quickie: Insert date and time into Notepad document

September 23rd, 2013 No comments

When I do some change I note when and what I have done. I use notepad. I used to type date and time to every step I made, for example during migration. My colleague Robert Švec told me about key F5 which puts actual date and time into notepad document 🙂

That’s just a quick quickie today.

Quickie: Too many events 106 in Exchange 2010

August 22nd, 2013 No comments

At one Microsoft Exchange 2010 server I was receiving too many events number 106:

Event 106

This event basically describes problem with some performance counter. I had problems with about 10 performance counters and I didn’t want to deal with them separatelly. Exchange 2010 has definition its performance counters stored in directory “C:\Program Files\Microsoft\Exchange Server\V14\Setup\Perf\”. There are XML files which define performance counters. Before you can manipulate with performance counters you need to run Exchange Management Shell and run in it following command:

add-pssnapin Microsoft.Exchange.Management.PowerShell.Setup

This Snap-in allows you to use two Cmd-lets:  Remove-PerfCounters and New-PerfCounters. So let’s do two things which help us to get rid of events 106:

Deregister all performance counters for Exchange:

[PS] C:\Program Files\Microsoft\Exchange Server\V14\Setup\Perf>dir *.xml | foreach { Remove-PerfCounters -DefinitionFileName $_.Name }

Register all performance counters for Exchange:

[PS] C:\Program Files\Microsoft\Exchange Server\V14\Setup\Perf>dir *.xml | foreach { New-PerfCounters -DefinitionFileName $_.Name }

Since I reregistrered all performance counter definitions into Exchange 2010 server I have no problem with event 106.

This was quickie for today 🙂

Quickie: List FSMO roles from command line

August 15th, 2013 2 comments

I always don’t remember commands to list all FSMO roles in domain so I decided to take a quick note into my diary 🙂 :

  • Connect to domain controller
  • run ntdsutil
  • write roles
  • write connections
  • write connect to server SERVER_NAME
  • write q
  • write select operation target
  • write list roles for connected server

 

More sexy command is

netdom query /domain:DOMAIN_NAME fsmo

 

and viola. I know it’s dummy post, but I had to wrote it down 🙂

 

Problem with WSUS client

August 14th, 2013 No comments

 

Today I had problem on one server Windows Server 2008 R2. This server logged error 800B0001 with Windows Update Client:

 

Error 800B0001

 

When I looked at event viewer I saw same error:

  error 0x800b0001

 

and WindowsUpdate.log logged following:

 

 

I knew about one issue which is described in this article. But this article didn’t help. When I looked for file C:\Windows\SoftwareDistribution\SelfUpdate\wuident.cab, I found out there isn’t such a file. I copied this file from other server Windows Server 2008 R2 and now everything works fine 🙂

So in Microsoft world .cab file is not trusted if it doesn’t exist! 😀 Coool.

 

 

Change default language for AD FS 2.0

August 13th, 2013 1 comment

ADFS deafult changes language of its pages based on language sent from user’s browser. User’s browser sends http header called Accept-Lanaguage. This means that if, for examle, user with Regional settings set to Slovak accesses ADFS website, all pages are in Slovak language. When someone else comes with Regional settings set to English, all pages are in English language.

There was a need for one ADFS portal I implemented to change ADFS websites’ language to one static language – Slovak (multilanguage option shoule be set off). I digged into ADFS files stored deafult at C:\inetpub\adfs\ls\. After couple minutes I found file called Global.asax.cs which contained something about languages. After coulpe minutes trying to understand .NET I figured out what have to be done to change language to Slovak.

On line number 45 I found following line:

string requestedLang = acceptlang;

I changed this line to:

string requestedLang = "sk"

Since then everything works only in Slovak language. Just a remark: if you are using ADFS Proxy you have to change this settings on ADFS Proxy server. It doesn’t have to be changed on ADFS server (non-proxy).

Implementing Remote Assistance into context menu of ADUC

August 6th, 2013 5 comments

Couple days ago I wrote about Remote Assistance. I wanted to make this feature as close as possible to administrators so I decided to implement special item in context menu of ADUC. Let’s do it.

We need to prepare script first. I wrote very simple one:

==========


‘ Script to run Remote Assitance on domain computer

Set wshArguments = WScript.Arguments
Set objUser = GetObject(wshArguments(0))


‘ Check if Remote Assistance is installed

Set fso = CreateObject(“Scripting.FileSystemObject”)
If (fso.FileExists(“C:\Windows\System32\msra.exe”)) Then
 ‘ Is istalled
 Set objShell = WScript.CreateObject(“WScript.Shell”)
 Return = objShell.Run(“C:\Windows\System32\msra.exe /offerra ” & objUser.dNsHostName, 1, true)
Else
 ‘ Is not installed, error.
 Wscript.Echo “Microsoft Remote Assistance is not installed on this machine.”
End If

==========

Let’s save this script as .vbs file into \\DOMAIN.LOCAL\NETLOGON directory. Now when we have a script, we need to create context menu in ADUC. This can be accomplished using ADSI Edit tool. Start ADSI Edit tool and look for CN=409,CN=DisplaySpecifiers,CN=Configuration,DC=domain,DC=local. There look for CN=computer-Display. Right-click on CN=computer-Display and select Properties.

 

aduc01

 

In attribute adminContextMenu add following line:

2, &Remote Assistance,\\domain.local\NETLOGON\RemoteAssistance.vbs

Description:

2 – order number

&Remote Assistance – name of the item in context menu

\\domain.local\NETLOGON\RemoteAssistance.vbs – command to run

When you click OK, OK in ADSI Edit your work is done. Now when you click on computer account you can see and use following context menu item:

 

aduc02

 

And that’s all folks.

Quickie: Reset settings for w32time service

July 3rd, 2013 No comments

When you play with w32time service to much and you want to reset it to its default settings you can run following commands:

Active Directory Sync Tool – filters for user accounts

June 26th, 2013 2 comments

Today I published article how to make synchronization between Active Directory and Microsoft cloud Office 365. I also mentioned that you can filter which users you want to synchronize to cloud and which not. I also mentioned article where it’s described. I started to play with it, but it’s not as simple as I thought 🙂

They mention that you can filter on three conditions:

  • Based on OU location
  • Domain based
  • User attribute

I wanted to investigate third option – filter on User attribute. So I started to read article. First and most important is to mention that you set filter on users which you DO NOT want to synchronize. 🙂 So I decided to synchronize users which have their attribude “department” set to value “IT”. So I had to set filter out all users which don’t have this attribute set. 🙂

Another catch in article is about location of MIISAdmin tool. Article specifies some disk location, but it’s completely different. On my Windows Server 2012 it was installed in:

 

Installation directory

 

When I want to sync account which have department attribute set to “IT” I had to do following:

Open up miisclient.exe and click on Management Agents:

 

Management Agents

 

Right click on AD Connector (Agent) and Properties:

 

Properties

 

On left side you have to select Configure Connector Filter, then on right select user and select New…:

 

Sycn filter

 

Now declare new condition, which means we don’t want users that have department attribute set to IT:

 

Define filter

 

OK, OK. I set in domain only users User10-User19 to have value set. Now let’s force synchronization (IMHO it could be something more inteligent and nicer 🙂 ).

Let’s go to installation folder and run DirSyncConfigShell.psc1:

 

Running force sync

 

Now I have to run Start-OnlineCoexistenceSync:

 

Start-OnlineCoexistenceSync

 

You can check if everythin works fine in Application events and you should have success on the end:

 

Synchronization successed

 

And on cloud Office 365 I see just users I wanted to see:

 

Filtered users

 

Only thing I’m missing is to filter based on group membership.

Have a nice day,

 

Active Directory synchronization with Office 365

June 26th, 2013 1 comment

Once upon the time there was customer asking if we can help them with integration their Active Directory with Office 365 cloud. The main request was to sync Active Directory users into Office 365 cloud and then test Office 365 applications on their computers.

Registration for free Office 365

First you need to check prices and packages you want to use. I wanted to test it so I registered HERE. In free month you can use licences for 10 users. Don’t forget to register for Office 365 Midsize Business, only this version of Ouffice 365 can sync AD. After registration I have received e-mail with my account to log into Office 365 portal. After firt logon there is really not to many things to configure. I have to notice that I received testing domain @AtosSlovakia.onmicrosoft.com. This is what you need to have.

Preparing playground

So I have my playground setup:

  • Domain name: DOMAIN.LOCAL
  • Domain controller: MT-SERVER01.DOMAIN.LOCAL
  • Server which will synchronize data into cloud Office 365: MT-SERVER02.DOMAIN.LOCAL

Computer which will do synchronizaction needs to accomplished couple conditions:

  • Must have Microsoft .NET Framework 3.x
  • In cannot be domain controller
  • Must be part of the domain
  • It can be Windows Server 2008, Server 2008 R2 or Server 2012
  • If you have less than 50 000 objects in AD which you want to sync you can use Microsoft SQL Server 2008 Express. Other way you need to use “normal” SQL
  • Active Directory forest functional mode has to be Windows Server 2003 and higher

More HERE.

I also need to generate some users in domain which I will upload into cloud. I just have created 50 bulk users using following powershell script:

Create bulk AD users powershell

I have received testing domain suffix from Office 365 @AtosSlovakia.onmicrosoft.com so I have to set it as aditional UPN for new created users:

  • Open Active Directory Domain and Trusts
  • Right click on Active Directorz Domains and Trusts and click Properties
  • Type defined UPN and click OK

Setup Active Directory Synchronizaction

When you log on Office 365 portal you go to “users and groups” and select Active Directory synchronization Set up.

Activate AD Sync

Then you have to complete 6 steps (not really work to do) to make it work:

AD Sync Wizard

Activation of AD Sync tool can take about 24 hours:

24 hours activation

While we will wait for activation of feature, let’s install Directory Sync Tool on server MT-SERVER02.DOMAIN.LOCAL.

Quickie: Powershell not just for work

June 21st, 2013 No comments

I installed Microsoft Lync couple monts ago at one customer. He asked me when his licence will expire. I knew date when Lync was installed (28/2/2013) and expiration period for Microsoft Lync server (180 days). I used power of shell (powershell) to check it out:

Get-Data AddDays

How cool is that? I really love powershell 🙂
