iDialog update release (1.1)

BOUCETTA Christophe — Tue, 26 Jan 2010 04:12:00 GMT

Une mise à jour pour la version Iphone a été publiée. Cette mise à jour régle certaines problématiques concernant son installation :

Features:

Support for OCS CWA 2007 and 2007 R2 servers that are published behind an ISA Server using Single-Sign On (SSO) authentication. If you have deployed CWA using ISA SSO, the connection will now be seamless.
Support for Enterprise certificates. If your OCS CWA is configured with an internal certificate, the user is warned about the untrusted certificate and can choose to “accept” the certificate in order to proceed. This is the same behavior that is available in all major web browsers today. This will greatly improve the out of box experience for users at companies that have used an internal CA to issue their CWA certificate (or certain Public CA’s that have proved to be problematic for the iPhone platform).
Support for Distribution Groups (This feature is available only if your company has deployed OCS 2007 R2).
Robust connection status information and error messages

Fixes:

Improved speed and responsiveness.
Support for passwords with certain special characters.
Fix for intermittent app crashes when signed in to multiple OCS endpoints.

Virtualisation du poste de travail et Office Communicator

BOUCETTA Christophe — Tue, 26 Jan 2010 04:11:00 GMT

Le blog de Damien Caro apporte quelques réponses bien utile sur certains point concernant la virtualisation et office Communicator. La virtualisation du client Communicator est supporté mais uniquement dans le cas d'une virtualisation par AppV au niveau du poste client. L'état des lieux est clairement décrit dans cet article de la base de connaissance : http://support.microsoft.com/kb/951152/en-us :

Office Communicator 2007 and Office Communicator 2007 R2 support all native functions. This includes text chats, presence functions, desktop sharing (Office Communicator 2007 R2 only), Remote Call Control (RCC), audio, and video when you use them in Client-Side Application Virtualization mode (Microsoft Application Virtualization for Desktops 4.5).

Concernant l'autre mode de virtualisation, la virtualisation de présentation, (Terminal Server) apporte une couche d'abstraction supplémentaire au niveau du réseau qui perturbe les algorithmes de détection des modifications des conditions réseau (bande passante, latence, …) rendant l'expérience utilisateur potentiellement très mauvaise. La voix et la vidéo avec Office Communicator ne sont donc pas prêtes d'être supportés en environnement de type terminal serveur.

OCPE Device (Tanjay) Upgrade Guide

BOUCETTA Christophe — Mon, 25 Jan 2010 11:07:00 GMT

Rick Varvel a publié sur son blog un merveilleux guide permettant de mettre à jour les devices OCPE (Tanjay) en utilisant le service de mise à jour des devices d'office Communication Server 2007 R2 de manière tres détaillée, si je l'aurais eu avant, je me serais moins embêté :)

voici le lien de téléchargement : OCPE Upgrade Process 199_522_6907 for R2 (v1.5).docx

The presence information for a Communications Server 2007 user may not appear, or may appear intermittently, in Outlook 2003 Service Pack 2 or in Outlook 2007

BOUCETTA Christophe — Mon, 25 Jan 2010 11:07:00 GMT

Les informations de présence de Microsoft Office Communications Server 2007 peuvent ne pas appara^tre dans outlook 2003 (SP2) ou 2007. Cela arrive souvent quand l'URI SIP de l'utilsateur est différente de l'adresse email primaire de l'utilisateur ou quand l'utilisateur a de nombreuses adresses e-mail.

La Résolution :

Step 1: Add a SIP proxy address in Exchange Server for the user account that specifies the user's SIP URI

Microsoft Exchange Server 2003

Open Active Directory User's and Computers.
Double-click the user.
Click the E-mail Addresses Tab.
Click New.
Click Custom Address. Type the SIP URI in the E-mail address field, and then type SIP in the E-mail type field.
Click OK two times.
Wait for the Active Directory directory service and Exchange to synchronize.

Exchange Server 2007

By default, Exchange 2007 can obtain a Communications Server 2007 user's SIP URI from Active Directory and populate the SIP proxy address automatically.

Step 2: Add two registry entries (Outlook 2003 SP2 only)

Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click the following article number to view the article in the Microsoft Knowledge Base:

322756Â (http://kbalertz.com/Feedback.aspx?kbNumber=322756/ ) How to back up and restore the registry in Windows

Note This step is not required for Outlook 2007.

Outlook 2003 SP2 does not search for the user's SIP address to get the presence information. If a user's SIP proxy address and the user's default e-mail address are different, Outlook 2003 SP2 cannot show presence information. By adding the following registry keys for Outlook 2003 SP2, you can help prevent a problem if these addresses are different.

Click Start, click Run, type regedit, and then press ENTER.
Locate the following registry subkey:
HKEY_CURRENT_USER\Software\Microsoft\Office\11.0\Common\PersonaMenu
Click Edit, point to New, and then click DWORD value.
Type QueryServiceForStatus, and then click OK.
Double-click QueryServiceForStatus, type 2, and then click OK.
Click Edit, point to New, and then click DWORD value.
Type EnableDynamicPresence, and then click OK.
Double-click EnableDynamicPresence, type 1, and then click OK.
Exit Registry Editor.

Do not apply KB974571 to LCS/OCS Servers

BOUCETTA Christophe — Mon, 25 Jan 2010 11:06:00 GMT

Allez, encore une petite couche sur ce problème de mise a jour!

Update #1 - Until this issue can be resolved, I am only suggesting that you either hold off on deploying this update, or test very throughly to make sure that this won't cause an outage in your environment. Security updates are VERY important, and once this issue is resolved, you should deploy this update to all of your LCS/OCS servers.

Currently an issue is being observed after applying KB974571 (MS09-056: Vulnerabilities in CryptoAPI could allow spoofing) to LCS/OCS servers, that is causing them to believe that they are running an evaluation version of LCS/OCS and that it has expired.

http://support.microsoft.com/kb/974571/

If you apply the patch, the LCS/OCS services fail to start and you see these errors in the event log:

Check the previous event log entries and resolve them. Restart the server. If the problem persists contact product support.

Uninstalling the patch is the only way to currently fix this issue.

The issue is currently being escalated, but until a fix can be found, delaying the install of KB974571 is recommended.
