Windows 10–1607–LinkedConnections

So, lots of things have to fall into place for this to take effect, but here we go….

If you have UAC enabled (in some form or another) and have users that are able to run in two different contexts (elevated and non-elevated) with the same user account – it means that they are local administrators on the device. It also means…

.. that if they map a network drive in one context it will not be visible in the other context by default.

Microsoft created the great Linked Connection which will automatically allow the mapping of a network drive to be visible in both contexts.

Well, since roughly October 2016 this stopped working if you were running Windows 10 – 1607 with the October 2016 patch, and the user was local administrator on the device and mapped a drive in one context and also expected the EnableLinkedConnections to provide a smooth user experience – it simply stopped working.

To add insult to injury – if you map a drive within a login-script; the default context is elevated so the non-elevated process (such as explorer.exe) will not show the mapped drive.

As far as I can tell this is not listed as a known defect. Therefore its not listed as a fixed defect in the March 2017 patch for Windows (so, october.. november… december.. 6 months in total in a non-working state). According to Google (oh, what a reliable source for anything named Microsoft) Windows 10 – 1607 was noted as Business Ready (Current Business Branch) since 29 November 2016.

Ready for business, eh? Well – at least one step further….

Group Policy Preference and Scheduled Tasks

For some reason it’s always the details in the basics that are the longest hurdle to get over. This particular topic is something that always needs to be re-googled before the last details are sorted out.

Purpose

To create a schedule task to either run as the system-account or the interactive user via Group Policy Preference.

The detail:

When resolving SYSTEM the normally resolved identity is BUILTIN\SYSTEM. Interactive is normally not able to resolve at all. This normally results in the following error client side when attempting to apply the Group Policy

‘0x80070534 No mapping between account names and security IDs was done.’

What should be done?

Click the Change User or Group and select the domain of your environment, and proceed to select the Builtin-container. This will resolve both Interactive (running in the user context of the logged on user) and system to NT Authority.

Office and its poor handling of slow-links

Office is and has been a core application for a quite a while within most Windows environments.  This is a small list of things that have been adopted to make the user experience better for users not located close to the file-servers, or articles that allow you to understand why things happens.

Slow network performance when you open a file that is located in a shared folder on a remote network computer
Known issues with Office if Desktop or My Documents is redirected
An Office program is slow or may appear to stop responding (hang) when you open a file from a network location
Excel workbooks may open slowly over the network
Slow performance when you browse the My Documents folder in the document library in Windows 7 or in Windows Server 2008 R2

and for the PST / OST-files;

Limits to using personal folders (.pst) files over LAN and WAN links
Network Stored PST files … don’t do it!

Access

Using a wan with ms-access? How fast, how far?

Keyboard Layouts–cleanup the languagebar

Want to get rid of excess language settings? In an European environment it can be quite nasty and if your organization truly spans across the globe – multiple settings can conflict. Here is to set the record straight and cleanup things properly from a default / mandatory profile along with some major HKLM cleanup to smoothly offer the right keyboard layout for users.

RemoteFX Performance Counters

This is a pure copy-and-paste article from a Spanish blog about Performance Counters regarding the RemoteFX protocol within Windows Server 2012. Took me a long time to google it – so saving it here for use later on.

 

RemoteFX Graphics

Tivoli Storage Manager and SQL backup

The script that was used as a template for initiating the SQL backup from the TDP agent is simply a bat-file. It isn’t very complicated and quite basic. Since deploying this backup within a datacenter and dealing with a few different SQL-servers installed in quite a few different ways – it seemed that this script had as many variations as we had SQL-servers installed. The main flaws were around the fact that multiple SQL instances weren’t detected and that the transaction-log weren’t truncated when the backup had been run for databases that were set to recovery mode FULL. Inorder to make this more manageable the following improvements were made;

  • Detect all SQL instances via the local the registry – based on Jay’s blog
  • Exclude Windows Internal Databases
  • Run through all databases in each instance. Verify if there are any offline instances and databases
  • Backup all databases or each database that are online.
  • Run a backup of transaction log and truncate it – some things based on SpaghettiDBA
  • Track all errors and exit the command with the error if one occurs to allow TSM to report a failed backup

It does not;

  • Detect if a SQL instance is offline
  • Detect if SQL is not installed and then fail

Why a bat-file?
All servers we are supporting doesn’t have Powershell. A reality…

TSM 6.2 Query–Time Calculation

Apparently they redid a couple of things with IBM TSM 6.2 – which allowed a good half of a day to understand the DB2 query language and howto manipulate it.

Apart from the node-name (which should be fairly basic) – the following is the end-result for my finalized query which shows the elapsed time of a job (backups in this specific case) – and providing it in a D HH:MM: SS format. Its so much easier to read.

System Event Notification Service, App-V and logon failure

Located a very nice KB-article and wanted to be able to locate it again – hopefully it becomes more searchable using key words involved! Thanks to Justin Zarb for the find – personally, this was missed in a spreadsheet of articles that should have been on top of my head.

You may experience the following issues after you log on to a computer that is running Windows 7 or Windows Server 2008 R2:

  • Your desktop does not load. You only see a blue or black background image.
  • Windows Explorer does not run, and you cannot access your data.
  • You receive the following message in a notification balloon:

Failed to connect to a windows service. Windows could not connect to the System Event Notification Service (SENS). This problem prevents limited users from logging on to the system. As an administrative user, you can review the System Event Log for details about why the service didn’t respond.

When the issue occurs, a service host that contains the following services crashes on system startup:

  • Certificate Propagation
  • Extensible Authentication Protocol
  • Group Policy Client
  • IKE and AuthIP IPsec Keying Modules
  • IP Helper
  • Server
  • Multimedia Class Scheduler
  • User Profile Service
  • Task Scheduler
  • System Event Notification Service
  • Shell Hardware Detection
  • Themes
  • Windows Management Instrumentation

You may experience this issue after you install certain applications, for example Microsoft Application Virtualization Client ( App-V ), on the computer.
Note You have to restart the computer one or more times to recover from this issue.
