Citrix XenApp failed to connect to the Data Store.

October 16th, 2014 by Jack Cobben No comments »

Today I needed my XenApp 6.5 server to check something in my lab and I wasn’t able to run the discovery of my XenApp farm. I checked the services and they were running fine (IMA, MFCOM etc). In the event log however I saw these nice messages:

  • Event ID 3889

Citrix XenApp failed to connect to the Data Store. ODBC error while connecting to the database: 28000 -> [Microsoft][ODBC SQL Server Driver][SQL Server]Login failed. The login is from an untrusted domain and cannot be used with Windows authentication.

  • Event ID 3612

The server running Citrix XenApp failed to connect to the Data Store IMA_RESULT_ACCESS_DENIED. Invalid database user name or password. Please make sure they are correct. If not, use DSMAINT CONFIG to change them.

  • Event ID 3632

The server running Citrix XenApp failed to connect to the data store. Invalid database user name or password. Please make sure they are correct. If not, use DSMAINT CONFIG to change them. Error: IMA_RESULT_ACCESS_DENIED Indirect: 0 Server: DSN file: C:\Program Files (x86)\Citrix\Independent Management Architecture\mf20.dsn

I recently moved my SQL database (hosted on hyper-v machine) from 1 server to another (complete new server as old hardware needed replacement) and SQL server VM was moved (no restore, exported VM and imported VM). IP addresses are the same etc.

With the following command I got the database connection back and restarted the IMA service.

C:\Users\administrator.CTXTST>dsmaint config /user:domain/user/pwd:password /dsn:”C:\Program Files (x86)\Citrix\Independent Management Architecture\mf20.dsn”

After this I was able to connect to my XenApp environment again :).

 

 

 

XenDesktop and XenApp 7.6 feature overview

September 10th, 2014 by Jack Cobben No comments »

With the upcoming release of XenDesktop/XenApp 7.6 Citrix has released an overview of the features available per license model:

 

Meet the demands of any use case

XenApp Advanced XenApp Enterprise XenApp Platinum XenDesktop VDI XenDesktop Enterprise XenDesktop Platinum
XenApp published apps (Server-based hosted apps) can be deployed on 5 generations of Windows operating systems, enabling secure access to Windows apps on any type of device including iOS, Android, Mac and Windows devices for on-demand access from anywhere, lets users focus on work.
XenApp published desktops are low-cost, locked-down virtual desktops that provide the flexibility and mobility benefits of desktop virtualization while maximizing IT control through enhanced security and simplified management.
VDI desktops offer maximum user personalization of a persistent Windows virtual desktop that can be fully customized to meet the needs of your most-demanding users.
VDI with Personal vDisk pairs the maximum user personalization benefits of VDI with the storage optimizations and administrative efficiencies of single image management to deliver a desktop virtualization solution that meets the needs of both users and IT admins.
Server VDI enables enterprises and service providers the ability to deliver to an individual user a single session, server-based virtual desktop from the cloud.
Hosted physical desktops enable high performance remote access to physical desktops securely protected in the datacenter for optimal data protection, especially beneficial for graphically intensive applications that run best on a native OS that has direct access to the physical desktop hardware.
Remote PC Access (with Wake On LAN) instantly delivers desktop virtualization benefits without the need to migrate desktops to the datacenter by providing users with a secure, high-definition, direct connections to their office PCs.
Offline client virtualization (XenClient Enterprise)extends the benefits of desktop virtualization to people who need to work from anywhere including offline, by enabling them to work in a disconnected state thereby extending use case flexibility.
DesktopPlayer for Mac (Add-on*) extends the benefits of XenDesktop to MacBook users, enabling them to run Windows desktops on a Mac whether they are online, offline, or even experiencing a slow or intermittent network connection. End users gain freedom while IT gains control by centrally managing Windows virtual desktops deployed to corporate and BYO MacBooks.

*Add-on purchase required

VM hosted apps ease Windows OS transitions and overcome application compatibility challenges in a multi-user, server environment.
Pre-launch technology creates a local-like app launch experience by expediting the session creation process.  With pre-launch, a session waits for the user in an active or disconnected state, enabling quick, instant-on app access to an already active app session making for a fast and local-like app launch experience.  Pre-launch configurations have been improved on the FMA platform, making it simple to configure from the Citrix Studio management console.

Available with Receiver for Windows.

*Feature of XenApp

Session linger keeps the user session open after the user closes the app, to provide a quick app reconnect or enable the user to open a new app without repeating the logon process. Admin-configurable time-based policy automatically releases a license consumed by a pre-launched and lingering session to improve license management.

Available on all Citrix Receivers

*Feature of XenApp

Unauthernticated user (anonymous logon) enables administrators to authenticate users at the applications. Employees get instant, unauthenticated access to a single app while access to other, more personalized apps such as email remains authenticated.
Support for USB 3.0 devices with automatic drive mapping and redirection provide users a plug-n-play capability with the latest web cams, microphones, headsets and other peripherals to enhance the user experience within published app sessions.

reconnect only to published desktop or application

June 17th, 2014 by Jack Cobben No comments »

Hi guys,

If you ever find yourself in the situation that you want to be able to only publish applications or desktops to your users you can can create two stores (1 for the applications and the other for desktops). You can configure both stores to point to the same XenApp/XenDesktop farm/site. This blog post by Feng Huang describes the configuration of the StoreFront Store in great detail.  When you have this configured and you connect to the Desktops only store, you are only able to (re)connect to desktops. Any opened or disconnected published applications won’t be reconnected from that store. Vice versa this works off course the same, open or disconnected published desktop(s) aren’t reconnected when connecting to the Applications only store.

 

Book Review: Citrix XenMobile Device Management

April 27th, 2014 by Jack Cobben No comments »

2147ENI had the opportunity to review this book published by Packt Publishing and written by Akash Phoenix.

I have no affiliation with either the author nor Packt publishing.

This book takes you through the installation and configuration of all necessary products and explains it in simple layman’s terms(with pictures and clear text). Configuring NetScaler, licensing and certificates are discussed. Also some really basic troubleshooting steps are provided in the small but very easy to read book.

What I miss in this book is an in depth approach to all the features XenMobile has to offer. Troubleshooting chapter (1 page) is really basic and doesn’t provide anything you really need to check when the *@# hits the fan….

If you don’t have any understanding of Citrix XenMobile Device Management this is a must have to start with. Every step is clearly explained and detailed what to configure. For the more experienced Citrix XenMobile admin this book can be too easy and misses the depth for configuring and advanced troubleshooting of this great product.

Heartbleed OpenSSL security and Citrix

April 17th, 2014 by Jack Cobben No comments »

large-hero-heartbleedAs alll of you know by now, and if you don’t you have been hiding under a very big rock, OpenSSL had a very big bug in it’s design which causes unwanted people to gain access to encrypted traffic.

As a Citrix employee I’ve been asked several times if and what products of Citrix are affected by this heartbleed security issue.

Well, this KB article is updated as needed and provides information on current Citrix products that are affected and what update you need to install. It also lists 3rd party updates on which Citrix relies on if they are affected.

Last but not least it lists a complete list of Citrix products that aren’t affected :).

Book review Citrix XenDesktop 7 cookbook

April 17th, 2014 by Jack Cobben No comments »

7463EN_Citrix Cover.jpgPackt publishing contacted me recently to review a new book they published on Citrix XenDesktop 7.

Gaspare A. Silvestri has written this book and does explain all the various settings and features of XenDesktop 7. Even if you aren’t experienced with this product he will guide you through this one and keep you interested in knowing more about this product.

As you all know I’m a great fan of using screenshot to enhance the readability of a document/post or book. Gaspare does this also in this book and it makes it easier to read and even helps you in where you can find certain settings.

If you don’t have this book yet, I would recommend it to add this to your bookshelf and read it.

Hope you find this review usefull.

Until the next book review or blogpost wlEmoticon-winkingsmile.png.

empty outlook folder pane after Windows updates

September 11th, 2013 by Jack Cobben No comments »

Like a good MS supporter (ahum) does is install the Windows Updates every month. last night I updated my Win 8 system with the latest patches and this morning I cam across this beautiful Outlook folder pane:

outlook pane

After uninstalling kb2810009 and kb2817630 the folder pane was back again.

Hopefully Microsoft will fix this bug soon….

Just my 2 cents for today.
