Quickie: Right click using keyboard

April 29th, 2014 No comments

In my class today we needed to do right-click in Windows using keyboard. I just found out that Shift + F10 simulates right-click 🙂

That’s all for today,

Quickie: Tail in Powershell

February 28th, 2014 2 comments

There is lots of great tools in Linux which are needed in Windows environment. One of the great tool from linux is “tail”. You can use it following way:

tail -f /var/log/mail.log

You will get end of the file and you see all content added to file on screen. You can view log files without need to reopen it. In Windows I use utility Trace32.exe. I was looking for some more native way to do it in Windows. There is a cmd-let Get-Content in Powershell which you can use following way:

Get-Content C:\Windows\WindowsUpdate.log -Wait -Tail 10

This tails only 10 lines from the end of the file and “waits” for new added lines. Switch “Tail” is accessible only in PowerShell 3 and higher.

Powershell is getting there,

Quickie: Exchang database migration over 24 hours

December 9th, 2013 No comments

Over the weekend I was setting up Exchange 2010 database copies using DAG. Those databases were huge (total of 3,5 TB). Line between primary and backup datacenter was 100Mbps. This migration ran over 24 hours for couple databases. When I checked the status I saw job was running 23 hours and 20 minutes:

When I have checked status in about hour and half I saw interesting time:

This happened on all databases which ran over 24 hours 🙂 So it looks like Microsoft engineers haven’t think about job running more than 24 hours 🙂

That’s all from weekend,

Quickie: Nice utility to check DNS in AD

November 19th, 2013 No comments

Where there is a problem with AD replication, there is most of the time problem with DNS. Most of the time there are bad DNS records or missing DNS records. There is cool utility to check DNSLint.exe from Microsoft. It is designed to do all manual check I do when trying to solve AD replication problems.

You can download it from here and also read more about it.

It’s bad it’s not included into operating system by default.

Quickie: Delete all Offline files on Windows XP

November 19th, 2013 No comments

Couple days ago I migrated fileserver. We moved redirected My Documents for users on another server. We also hided these shares behind DFS namespace to make it more manageable in future. But we found out problem with this setup –  offline files. Windows XP kept offline copies of old and new redirected files. We had to clean this offline data database. I setup start up script:

@ECHO OFF
IF EXIST C:\OfflineFilesClean.txt (
  REM Do one thing
) ELSE (
  reg.exe add “HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\NetCache” /v FormatDatabase /t REG_DWORD /d 1 /f
  echo Vymazane > C:\OfflineFilesClean.txt
)

This script was dedicated just for Windows XP, so I had to apply GPO using WMI filter:

SELECT * FROM Win32_OperatingSystem WHERE Version LIKE “5.1%” and ProductType = “1”

This script would work also on Windows 7 and Windows 8, but those OS didn’t have problem.

That’s all for today,

Quickie: When you disable Data Decuplication you will lose Shadow Copies data

October 22nd, 2013 No comments

We had some problems with backup system backing up Windows Server 2012 deduplication enabled volumes. We decided to disable Data Deduplication on volume. After volume was converted back into “non data deduplication mode”, we found out that all Shadow Copies meta data was lost. It means all “Previous Versions” were lost. I really don’t see any reason to act like that, but there is probably some. It would be great if Windows warns you before you do the change. But it doesn’t 🙂

Have a nice day,

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 🙂

 

Quickie: DOSKEY macro

July 29th, 2013 2 comments

Couple times in row I write on command line commands which are misspelled. One of my most popular is command exot instead of exit. 🙂 So I started to look around how I can fix my quick fingers. There is one built-in utilitky to create macros in command prompt (cmd.exe) and it’s called DOSKEY. So I started to play with it and I defined my first command macro:

C:\Users\Cievo>DOSKEY exot=exit

and now let’s list my first macro:

DOSKEY MACRO

There is one bad thing about this macros. There are active only in current session. This can be solved by exporting all macros into file and import this file everytime you start command prompt. To export macros you can use command:

C:\Users\Cievo>DOSKEY /MACROS:ALL > my_macros.cmd

When you want to import your saved macros, you have to just run file my_macros.cmd.

That’s it and now “exot” 🙂
