Steps for shrinking a vmware disk for a Windows guest VM inside VMware Workstation of VMware Fusion

Posted by jpluimers on 2014/01/13

Another one from the “missed schedule” series, this one was originally scheduled for 20130927.

These articles were not very clear on the actual steps to take:

Windows security Token Bloat

Posted by jpluimers on 2014/01/13

This can happen when your Windows Security Token bloat has struck:

… the problem could be minor, or relatively major. You may get weird access denied messages, applications crashing, or strange entries in your event logs. Or worse yet a SID for a group that has a ‘deny permission’ on an object could be dropped into the virtual bit bucket, allowing a user to access a resource they are not supposed to access.

Summary of fixes for token bloat:

  1. Use global or universal groups instead of domain local.
  2. Increase the MaxTokenSize on all computers
  3. Convert security groups to distribution groups if they are only used for email lists.

There is a hard-coded limit of 1,024 SIDs for the Kerberos PAC (privilege attribute certificate)

Kerberos token size still remain to 64k in windows7 / win2008r2.

This is what UWWI did to avoid token bloat: UWWI Token Bloat – IAM – UW Information Technology Wiki.

Accessing Mac Hard Drives from Windows 7/8: Boot Camp Support Software 5.0.5033

Posted by jpluimers on 2014/01/07

If you want to read  a Mac HFS+ formatted disk from Windows 7/8 then you can use the Boot Camp Support Software 5.0.5033.

It is a large download (about half a gigabyte, uncompressed 800+ megabyte) of which you need only this file:

  • BootCamp5.0.5033.zip\BootCamp\Drivers\Apple\BootCamp.msi

When you want to write HFS+, then MacDrive works fine and has a 5-day fully functional trial (so you can verify really large files transfer fine).

The other way around is built in, but not enabled by default. To have a Mac read and write NTFS volumes, you have to edit your /etc/fstab file as explained in will mountain lion read/write to an…: Apple Support Communities to which I added some hyperlinks. Note there are also NTFSFree and OSXFuse (which is the successor of MacFuse). Read the rest of this entry »

Outlook + Outlook express: email received from Outlook sender does not have any attachment in Outlook Express

Posted by jpluimers on 2014/01/03

A friend of mine uses Outlook Express because that has been with Windows since very early on, and before that with Internet Explorer from version 4 till version 6.

He is the kind of person that does use a computer, but doesn’t like change. No wonder, as he is well into the retirement age and the systems he has used in the past all lasted for a very long time.

So it is going to be a big change for him when he needs to upgrade from Windows XP – that he used for over 10 years – to something else. Probably more on that in a later stage (if Windows Live Mail exists by then).

Back to the problem at hand: he couldn’t see attachments from certain Outlook users, though those users insisted .

I hadn’t used Outlook nor Outlook Express for a long while but it was fairly easy to track down the cause by viewing the message source in either of these two ways:

As soon as you see the full message source, there is a ms-tnef encoded Winmail.dat attachment in the affected messages. You find it by searching for a line that starts with “begin” followed by 2 spaces, “666” or “664” (it is one of the means to fake UUencoded attachments and hide text from Outlook Express).

Winmail.dat is known to cause all sorts of problems, even the NY Times devoted an article about it. It basically encapsulates the content of a message including any attachments into RTF: a Microsoft proprietary – but documented – standard of encoding formatted text.

Outlook Express does not cope with Winmail.dat well: it is a typical example of the one hand doesn’t know what the other is doing.

The “trick” is to configure Outlook for using HTML to format text (or use plain text without formatting) instead of RTF. You can do this either globally, or per recipient in the address book:

So when you use Outlook Express, ask the sender not to use RTF.

Know your enemy: Hacking Microsoft Remote Desktop Services for Fun and Profit

rdesktop: A Remote Desktop Protocol client (open source, runs on X, hosted on sf.net)

Posted by jpluimers on 2014/01/02

Very interesting, especially since rdesktop.org works with Windows Server 2008 R2 and Windows 7 as well, and is stable on x64.

It provides three tools: rdesktop, rdpproxy and seamlessrdp.

Researching this, I also found about TSWindowClipper which allows you to seamlessly integrates remote apps on your client by integrating a DLL inside the MSTSC software using the official virtual channels.

Back to rdesktop: I really wish the documentation was better, but it contains some very interesting source code.

rdesktop is an open source client for Windows Remote Desktop Services, capable of natively speaking Remote Desktop Protocol (RDP) in order to present the user’s Windows desktop. rdesktop is known to work with Windows versions such as NT 4 Terminal Server, 2000, XP, 2003, 2003 R2, Vista, 2008, 7, and 2008 R2.

rdesktop currently runs on most UNIX based platforms with the X Window System, and other ports should be fairly straightforward.

rdesktop is released under the GNU Public Licence (GPL), version 3. Please send feedback, bug reports and patches to the appropriate mailing list. Patches can also be submitted to the SF patch tracker.

rdesktop is a project. See the Sourceforge rdesktop project info and the Wiki for more information.

Status

The latest stable version of rdesktop is 1.7.1 (edit: this was at the time of writing, for the current latest, check here). This versions solves major issues with 64bit version and smartcard support among a few minor fixes.

Top 10: Windows Firewall Netsh Commands (via: Windows Server content from Windows IT Pro)

Posted by jpluimers on 2013/12/24

For my own reference, especially since setting the network profile in Windows 8 from the UI got much more difficult.

It is doable though, but not in logic places; I like the secpol.msc way most: windows 8 – How do I set my wireless network to be private instead of public? – Super User.
Same for renaming the network, which also has a secpol.msc way that is easy:

  1. Press Win+R, then type secpol.msc
  2. Click on “Network List Manager Policies”
  3. Double-click on your network
  4. Optionally give your network another name
  5. Click on “Tab Network Location”
  6. Set “Location Type” to “Private”

Go back to Network and Sharing Center to check the result.

To start the Network and Sharing Center:

control.exe /name Microsoft.NetworkAndSharingCenter

including:

  • Checking if the current profile is set to private/public/domain:
