Many times I have had issues with starting the OCS services on a consolidated front-end starting (fortunately, this has been mostly confined to lab environments). For the benefit of others, here are the 4 most common reasons for OCS service logon failures that I have experienced: The OCS Service Logon Accounts Have Expired. Event log errors 7000 [...] If the left-hand side of your users’ SIP addresses contain a common user attribute in Active Directory such as first name, last name (or both) there is a good chance the SIP address will need to be updated to match any change in the corresponding user attribute(s). The thought of changing an important attribute like the [...] After a lengthy work in progress, I am pleased to share a Microsoft Unified Communications Client Deployment script that I think will help some deployments rollout Office Communicator, Office Live Meeting, and the Office Live Meeting Outlook Add-In. You can view the script, download it, and read about the features here. It is 1500+ lines of [...] There have recently been several noteworthy changes to the Microsoft TechNet OCS and UC resources available on TechNet. Here is a summary of the changes: 1) The OCS TechNet Forums have Moved If you have never used them before, the Microsoft OCS TechNet Forums are a great resource for asking questions and resolving problems. As of last [...] A quick but important reminder for those deployments upgrading their user clients from Office Communicator 2005 to Office Communicator 2007 or 2007 R2. When an OCS user gets enabled for Enhanced Presence, either through the OCS management console or programmatically (through a script modifying AD directly or the WMI provider), Communicator 2005 users can still login. [...] The ability to transfer files in Office Communicator is an effective collaboration feature (and is often underused). A file can be shared in the context of a discussion by dragging-and-dropping it directly in the Communicator conversation session window. It is real time, and you avoid the storage headaches and application-context-switch that email attachments can bring. From [...] In case you missed it, as reporting by several blogs and the Microsoft Office Communications Server team, a recent O/S patch may cause your LCS 2005, OCS 2007, or OCS 2007 R2 servers to think they are an evaluation version which has expired, and the OCS services will not start (e.g. after a reboot). Fortunately, uninstalling the patch fixes [...] I was recently involved in a situation where the SIP domain was different from the internal AD domain. This could be the case if your organization supports multiple SIP domains, or you have a “split-brain” DNS configuration (i.e. there is one DNS zone for the outside world such as “example.com”, and another DNS zone used [...] OCS installs a set of Windows Management Instrumentation (WMI) classes that expose a wealth of information on everything from global settings about an OCS deployment, OCS user settings, or configuration information about a particular server. These classes can be used to programmatically gather configuration information, manage an OCS environment, and automate administrative tasks using a [...] There are several administrative uses for manipulating user contacts – the two primary uses are backup & restore, and inserting a standard set of contacts for an organization or department. There are two options available to import and export user contacts which I explain below. 1) Command Line Tool (DBIMPEXP.EXE) DBIMPEXP.EXE is a little-known tool which can [...] |
