Lync Server Documentation Update on April 2011

May 02, 2011 By: Yann Espanet Category: KB articles, Lync, Whitepapers

New Documentation and Tools Available

Updates to existing topics

Certificates and Wildcards

In addition, we clarified some of our guidance around certificates and wildcards. Lync Server 2010 supports wildcards only in the SAN and not the subject name.

For more details, see the following topics:

Migration Updates

Operational Guidance

New topics about Lync Server Control Panel have been added to the Operations, Planning, and Deployment sections of the documentation. The documentation now includes tips to troubleshoot access to Control Panel. To accommodate these and other updates to software requirements, permissions, and procedures for administrative tools installation, we added some new topics, as well as restructured other topics and sections. For details, see the following topics:

We also updated information about Enterprise Voice branch-site resiliency to address recommendations regarding policy and dial plan configurations for different routing scenarios, as well as guidelines for handling call rerouting in outage scenarios, particularly for phone numbers that include extension numbers. For details, see:

Topics about creating Quality of Service (QoS) policies were updated to include the executable names for components for which you can enable QoS. For details, see:

The recommendations for choosing between deploying Survivable Branch Appliances or Survivable Branch Servers for branch-site resiliency have been updated. For details, see the following topic:

The procedure to enable QoS on Windows Server 2003 and Windows XP now specifies that you use Group Policy to modify default Differentiated Services Code Point (DSCP) values. The topic now also includes the default DSCP values for the IP packets for audio and video. For details, see the following topic:

The time interval that you can configure Lync 2010 to wait between connection attempts to Lync Server 2010 have been corrected to state that the accepted values are between 1 minute and 60 minutes.

Planning Updates

The Planning documentation for Enterprise Voice now contains additional clarification about requirements and recommendations for Mediation Server topologies. For details, see:

Enterprise Voice content was also updated to remove references to dual-forking to reflect that dual-forking is not supported in Lync Server 2010.

Clarification has been added to various topics that refer to the Enterprise Voice media bypass feature to explain that media bypass does not interoperate with every PSTN gateway, IP-PBX or SBC, also known as peers of the Mediation. Media bypass is supported only with products and versions listed at Unified Communications Open Interoperability Program – Lync Server.

Deployment Updates

Deployment documentation has been updated to specify that server in-band provisioning settings take precedence over settings configured by the user on the client. For details, see the following topic:

March Updates

In case you missed the March updates, they included the following:

In addition, we corrected the following errors found in our documentation:

  • We corrected our guidance on deploying Edge Servers. Previously, our documentation said that deploying Edge Servers in an Active Directory domain was not supported. That was an error. This is now corrected in the Deployment Best Practices for External User Access topic.
  • We also clarified the SQL Server database collocation and database instances. The supportability topics and all other topics referencing database collocation are now updated.

Choose between insecure or “not working” : To apply or not MS Crypto API security update KB974571 on OCS …

October 19, 2009 By: Yann Espanet Category: KB articles, Office Communication Server

You have to choose between beeing secure or stop working with OCS according to Microsoft !:

Your evaluation period may be expired with this error in event viewver :

Event source: OCS Server
Event id: 12290
Event text: The evaluation period for Microsoft Office Communications Server 2007 R2 has expired. Please upgrade from the evaluation version to the full released version of the product.

So, you follow the “Upgrading Office Communications Server 2007 Evaluation to the Full Released Version” document :

http://www.microsoft.com/downloads/details.aspx?FamilyId=54A5521D-A928-46F2-8BF7-125DA636DD2E&displaylang=en

BUT here’s the result :

OCS Setup log :

Failure
[0xC3EC78D8] Failed to read the Office Communications Server version information. This can happen if the computer clock is not set to correct date and time.

 

After some research I’ve found that the workaround was to remove the MS Crypto API security update KB974571. So I removed the update, rebooted the machine, and OCS 2007 R2 was up and running again, without any issues.

What is the position of MS regarding this issue :

http://support.microsoft.com/kb/974571/en-us

Microsoft recommends to postpone installing KB974571 on any LCS 2005 / OCS 2007 /OCS 2007 R2 servers.

Microsoft is investigating this issue, and will determine the most appropriate way to address it. Customers who are not running OCS or LCS server are not affected by this known issue, and can safely ignore this issue.

Customers who have deployed the OCS or LCS product on a server should assess the risk that is involved to decide whether to install the security update on that server. These customers should revisit this Knowledge Base article often, because this article will be updated as soon as more information and a resolution are available.

Nice one from MS !

Patch your Exchange Server ! – Critical Vulnerabilities Allow Remote Code Execution (959239)

February 12, 2009 By: Yann Espanet Category: Exchange 2007, KB articles

Microsoft has released a critical security update for all versions of Exchange to patch a two critical vulnerabilities :

  • The first vulnerability could allow remote code execution with a special TNEF message sent to Exchange Server. TNEF is another name for the Microsoft Outlook Rich Text Format, and an attacker who successfully exploited this vulnerability could take complete control of system with Exchange Server service account privileges.
  • The second vulnerability is a denial of service with a specially crafted MAPI command sent to Exchange Server. An attacker who successfully exploited this vulnerability could cause the Microsoft Exchange System Attendant service and other services that use the EMSMDB32 provider to stop responding.

This security update is rated Critical for all supported editions of Microsoft Exchange 2000 Server, Microsoft Exchange Server 2003, and Microsoft Exchange Server 2007.
