New "Case of the unexplained" and "Malware hunting" session recordings with Mark Russinovich

3. November 2014 Posted by Ralf Petter

If you really want to learn how to solve problems in Windows i really recommend to watch the latest versions of this sessions at TechED of Mark Russinovich the creator of the Sysinternals tools.

In the Cease of the unexplained session Mark shows you how to analyze program crashes, sluggish performance, blue screens and other windows problems.

In the malware hunting session Mark explains how to use the fabulous sysinternals tools to detect and remove malware from your computer.

And the best thing about the sessions with Mark is that they are not only packed with very useful stuff, but are also very funny to watch. I like him to make jokes about Microsoft products although he is a Microsoft employee

Erweiterte Einstellungen in Desktop Policy funktionieren nicht richtig.

30. Juni 2014 Posted by Ralf Petter

In einem meiner letzten Posts habe ich gezeigt, wie man den "Masthead" von Notes 9 über eine Desktoppolicy beeinflussen kann. Leider sind aber die Dialoge des Domino Adressbuchs in der deutschen und französischen Version von Domino leider kaputt übersetzt worden. Es wurde nämlich der englische Begriff "enforce" mehrmals irrtümlich ins Deutsche ("Zwingend") übersetzt. Dies bewirkt, dass zwingende Policyeinstellungen nicht richtig übernommen werden. Glücklicherweise kann dieses Problem aber  relativ einfach  mit dem Domino Designer behoben werden.

Die IBM hat dies in einner Technote mit einer genauen Anleitung zum Beheben des Problems dokumentiert. Der Fehler sollte in Version 9.0.2 behoben sein. Es empfiehlt sich natürlich immer trotzdem einen PMR zu öffnen, damit das Gewicht des Problems erhöht wird. Ich habe das mit PMR 48798 060 618 erledigt.

Ask the Experts Q&A session Managing Domino Upgrading and Migration transcript is available

25. Juni 2014 Posted by Ralf Petter

IBM hosted and Ask the Experts Q&A session  about Domino Upgrading and Migration on June 3, 2014. The Audio replay and the transcript of the FAQ is now available on developer works. Very Interesting questions and answers. If you upgrade your Domino infrastructure in the near future i strongly recommend to listen to this session.

Configure the Notes 9 Masthead (ShortcutButtonBar) with a desktop policy

24. Juni 2014 Posted by Ralf Petter

One of the new features of Notes 9 is the Masthead which is a shortcut bar to access often used functions in Notes. The user can configure which icons will be shown in the view menu of the Notes client. But what if you want to preconfigure this feature for your users on roll out? Although in the Desktop policy are no settings for the Masthead, you can configure this with managed settings.

The settings which icon are available is stored in the "" file in the "workspace\.metadata\.plugins\org.eclipse.core.runtime\.settings" folder in your data directory. To add an action add a line to this file with the id of the action set to true. To remove an action add the id with false.

For example to remove Mail from the Masthead add "100=false" to the file.

The id's which are available by default in  Notes are:

100 (Mail)
101 (Calendar)
102 (Contacts) (Homepage) (Workspace) (Discover)

In a later post i will show you how to add your own applications to the Masthead.

Because it is not very convenient to edit the "" file manually let's set the above setting with a Desktop policy:

  • Create a new Desktop settings document, or edit your existing one in Domino Administrator.
  • Go to the Managed Settings on the "Custom Settings tab".
  • Click the "Edit list" button to edit your managed settings.
  • Add your settings to the list of the managed settings similar to my screenshot.
If you need detailed instructions how to add managed settings to your Desktop policy go to the new IBM Knowledge center for help.

Save your policy and wait till your notes client will refresh the policies. If you want to shorten the wait you can use my script to refresh policies immediately.

Temporarily disabling and re-enabling Notes roaming user status

18. Juni 2014 Posted by Ralf Petter

The roaming feature of the notes client works really well and i always recommend to use roaming on production systems, but there is one caveat, if you change the notes id of the client when roaming is enabled, you will get all sort of weird problems. So NEVER change the notes id while roaming is enabled on your client. Normally changing the id in the client is not necessary, but when i test readers field functionality i want a quick way to change the id without logout and relogin of my windows session. 

Fortunately with Notes 8.5.2 IBM introduced a Notes.ini setting with which one can disable roaming temporarily. So if you have the same usecase as i, add "DisableRoaming=1" to your notes.ini before you change the notes id to the id of another user. After you finish your testing, you can re enable roaming with "DisableRoaming=0" in the notes.ini.

You can find all details how this great feature works in the technote Disabling and re-enabling Notes roaming user status on the fly.

Holiday Readings or what i pack in my suitcase for this year holidays. (Part I)

11. Juni 2014 Posted by Ralf Petter

The holiday season is coming with big steps and so the every year question is,  which books should i pack in my suitcase (or load on my kindle ;-)) to learn new things and improve my skills in various IT topics.

My first priority this year is to improve my understanding of how Windows internals works and how i can solve typical problems in windows more efficient. The most efficient tool to solve windows problems is the Sysinternals suite. But to get the most out of this tools you need a deep understanding how they work and which tool is used for which use case. Fortunately the creators of the Sysinternals suite have written and published a reference manual. If you use the tools regularly you should really take this one with you on your journey.

Windows Sysinternals Administrator's Reference

If you want to go more in detail how Windows works you can have a look at the Windows Internals  books. This books target the windows system developer, but i think they are also a chest full of treasures for the advanced windows admin. Because many mystery problems in windows will become understandable when you know how windows works under the hood.

Windows Internals Part 2

All books are available as softcover and as Kindle Edition.

How Microsoft gurus remove malware and ransomware from their windows installation

5. Juni 2014 Posted by Ralf Petter

The readers of my blog knows, that i am big fan of Microsoft guru and creator of the sysinternals tools Mark Russinovich. So i was really happy that Mark has posted a detailed description how to remove spyware and ransomware from Windows when i got a computer from a friend full with trojans and spyware. With his hints it was very easy to remove the autostarted malware and make my friend a Happy camper again.

If you have also Windows installations to clean from adware, spyware and ransomware have a look at his blog post and his presentation which makes this task really very easy:

Hunting Down and Killing Ransomware by Mark Russinovich

As a bonus the presentation of Mark gives you a good introduction to the fabulous Sysinternals tools.

Beheben der Sicherheitswarnungvon Windows bei Dateien aus dem Internet

30. Mai 2014 Posted by Ralf Petter

Windows besitzt eine Sicherheitsfunktion die bewirkt, dass Dateien die aus dem Internet heruntergeladen mit einem speziellen Flag versehen werden. Durch dieses Flag kommt beim Aufrufen der Datei eine Sicherheitswarnung die einen darauf aufmerksam macht, dass das Ausführen dieser Datei potentiell gefährlich ist.

Bei komprimierten Dateien wird dieses Flag sogar auf alle in dem Archiv befindlichen Dateien vererbt. Diese Vererbung führt dazu, dass in dem Archiv befindliche Hilfedateien nach dem Entpacken nicht richtig funktionieren. Egal welches Hilfethema man anklickt, wird immer eine leere Seite angezeigt.

Deshalb empfiehlt es sich bei allen heruntergeladenen Dateien insbesondere bei Archiven von denen man weiß, dass Sie aus einer zuverlässigen Quelle sind, dieses Flag vor der Verwendung zu entfernen.

Dafür muss man einfach die heruntergeladene Datei mit der rechten Maustaste anklicken und den Punkt "Eigenschaften aus dem Kontextmenü auswählen. In dem Eigenschaftendialog kann man jetzt beim Punkt Sicherheit über die Schaltfläche "Zulassen" das Sicherheits Flag entfernen. Dann bekommt man keine lästigen Dialoge mehr und auch die Hilfefunktion funktioniert einwandfrei.

Windows 2012 R2 is a big step forward for Microsoft Server technology. I especially like the much improved Hyper V in Windows 2012 R2. For details watch the following presentation from Teched:

Print Screen Key freezes Windows

26. Mai 2014 Posted by Ralf Petter

Today i had a strange problem on my windows machine that every time i press the "Print Screen" key to capture a screenshot windows will freeze immediately. I thought that this is only a temporary problem,  but after a hard reset i got the same problem again after retrying to create a screenshot.

It took me some time to figure out that the problem is not bug, but a feature. Last week i have used the Windows Kernel Debugger on my machine and one of the feature of the Debugger is that when you press the "Print Screen" key the kernel stops and try to connect to a WinDbg session. When there is no Debugger attached it will wait infinitely. So if you have the problem that your windows freezes on print screen check if the kernel debugger is enabled.

To check/deactivate the debugger start "msconfig.exe" with admin privileges and disable the debugger in the extended options on the start tab.

IBM thinks that MCH3601 and the creation of dumps is normal behavior during a restore operation

23. Mai 2014 Posted by Ralf Petter

The readers of my blog know, that i am a big fan of the "IBM i" operating system, because it is the most stable and reliable system ever built. We have been using "IBM i" and its predecessor "OS/400" since 1993 and we had only one crash (V3R0M5) of the operating system since then. One other big advantage of the system is that backup and restore is an integrated part of the base operating system so that backup and restore is rock solid too. 

But two weeks ago my believe in IBM i got a big hit. We want to restore a library from our backup and made the mistake that one user was still in the application which uses this library. Normally this should result in a CPF3762 error and the file wich is in use should be skipped. But this time we got a unhandled MCH3601 in QSCJSDMP and many dumps and problem records. I do not think that a MCH3601 error and the problem records should be generated in such a situation so we canceled the restore operation and got a second problem that the cancel operation leaves an object in a damaged state in the library. I also think that a cancel of a restore should not leave objects in a damaged state. So i have opened a PMR 22505,060,618 and IBM responded after one and a half week of analyzing the problem with:

MCH3601 and the Creation of Problem records when an restore fails caused by a lock is working as designed. The problem that objects are damaged when a restore is canceled is also working as designed.

This answers are really very disappointing and i can not believe that IBM do not want to solve this problems.

Omit directories from a *LINK BRMS Backup

22. Mai 2014 Posted by Ralf Petter

BRMS (Backup Recovery and Media Service) makes it very easy to backup the complete IFS (Integrated File System) of an IBM i machine, with the "*LINK" entry in your backup control group.

But sometimes you want to omit some directories from the backup because otherwise the backup will block applications which have open files in this directories. An example for such directories are the /tmp or the log directories of the web servers. The option to omit directories from "*LINK" backups is a little bit hidden. There is a special Link List in BRMS called "QLNKOMT". Every omit entry in this list will be omitted in "*LINK" backups.

You can work with the lists with the "WRKLBRM" command. Then select option 2 in the "QLNKOMT" line to edit this entry.

Then add the directories you want to omit to the link list. You can add more directories with a "+" in the more values field.

Performance Tuning Guidelines for Windows Server

20. Mai 2014 Posted by Ralf Petter

The whole Internet is full of more or less useful tips for performance tuning on windows server. Many tips to change some mystery registry settings are not only not useful, but the can cause serious problems on your servers. Some popular performance tricks in the Internet make only sense in older releases and are obsolete in newer versions of Windows Server. You should really carefully evaluate every tip before you implement it on your production servers.

But why trust on tips from the Internet when there are very good performance tuning guidelines from the creators of Windows Server like the

Performance Tuning Guidelines for Windows Server (Windows 2008, 2008 R2, 2012)
Performance Tuning Guidelines for Windows Server 2012 R2

This guides are packed with useful tips&tricks and detailed explanations how Windows server work and which settings should be applied in different scenarios like File, Application or Web servers. My recommendation is to not change any settings on your windows server before you have read and understood the above documents!
