Every client (Office Communicator 2007 R2) in the office is reporting the problem "Cannot Synchronize Address Book". cannot synchronize address When I click this report for more details I'm seeing : "Cannot synchronize with the corporate address book. This may be because the proxy server setting in your web browser does not allow access to the address book. If the problem persists, contact your system administrator". We do not use a web proxy at all internally, so this message is not at all helpful. Whilst looking for solutions to this issue, most of my googling has turned up issues with certificates as the root cause, but I'm nigh on positive this isn't the problem here. I'm able to surf to the URL being sent from the OCS server to Communicator as the Address book URL, and I get no issues reported by Internet Explorer at all. What is concerning me most, is that checking in the IIS logs on the server which is hosting the Address book, I'm seeing no accesses at all from most of the machines in the office. The only ones which are showing up are a couple of Windows XP machines - whilst most of the others in the office are ru
entries (ok, that's a made up number, but there are a lot) about how to force Communicator 2007 R2 to do an Address Book (Galcontacts.db) update. These blog entries will talk about the July 2009 update for Communicator 2007 R2 and how it introduced a random delay of 0-60 minutes for Communicator 2007 R2 to download an updated GalContacts.db to prevent the network from getting hammered by so many clients downloading an updated GalContacts.db all at the same time. And yes, these blog entries also talk about a registry entry you can create called GalDownloadInitialDelay and creating a Dword set to 0 in order to force Communicator to do an instant update. Some blog articles that talk about this include: http://www.tincupsandstring.com/2009/12/01/forcing-address-book-download/ http://www.markc.me.uk/MarkC/Blog/Entries/2009/12/17_Force_Downloading_the_Address_Book_in_OCS.html Now I'm sure you are asking yourself why I am creating this entry? Is it just to repeat information that's already out there? Of course not! So, Communicator 2007 R2 is a 32-bit (x86) application. That registry entry works perfectly fine on x86 systems. But, if you are running on a x64 system, it won't. Why? Well, because when you run x86 applications on a x64 based system, it utilizes a system in Windows called Windows on Windows (WOW64). WOW64 has its own section within the registry called Wow6432Node. So let's say we take the registry key for our Communicator x86 (Communicator x64 not available) and run it on an x86 system. The following registry key works fine: Windows Registry Editor Version 5.00 [HKEY_CURRENT_USER\Software\Policies\Microsoft\Communicator] "GalDownloadInitialDelay"=dword:00000000 But let's say we have an x64 system. The above registry key will not work. We need to utilize the WOW6432Node part of the registry. The following registry key works for x64 systems: Windows Registry Editor Version 5.00 [HKEY_CURRENT_USER\Software\Wow6432Node\Policies\Microsoft\Communicator] "GalDownloadInitialDelay"=dword:00000000 Please make sure you back up your registry before making changes as making changes to the registry can be harmful to your system if not done properly.
