Problem

Seen while trying to enable a user (who is an administrator) On Microsoft Lync.

Error:
Active directory operation failed on “Servername”. You cannot retry this operation: “Insufficient access rights to perform the operation”

Solution

I’m more used to seeing this problem on Exchange server to be honest, it happens because of a system called the AdminSDHolder. Which defines administrative permissions. The proper way to fix this, is to make sure you have a separate account for administrative duties to your user account. However a lot of people still don’t like doing that, for all of those, heres how to get round the problem.

1. On your domain controller > Open Active Directory Users and Computers, and locate a user that you are having a problem with > View > Advanced > Select the security tab > Advanced > Permissions and Put a tick into “Include inheritable permissions from this objects parent” > Apply OK.

2. Try to enable the user again, repeat as necessary for any other users that generate the same error.

Particularly after a migration this can continue to be a problem, you can stop it on a domain wide basis by doing this.

KB ID 0000529 

Problem

Saw this on a brand new installation on my test bench, I left it overnight and the problem still did not resolve.

Solution

1. On the Lync 2010 Server launch the “Lync Server Management Shell” and execute the following command:

[box]Update-CsAddressBook[/box]

2. Go and have a cup of coffee, then come back and check in the event logs, you should see, Event 21005 (Sync has Started), 21010 (Sync has completed), 21056 (Details of the sync), and 21004 (Time of next sync).

3. If that does not rectify the problem you can (On a PC showing this error) Start > Run Regedit {enter} > Navigate to:

[box]HKLMSoftwarePoliciesMicrosoftCommunicator[/box]

Create or edit a the DWORD GalDownloadInitialDelay and set its value to 0

4. Close the Lync Client and delete the GalContacts.db and GalContacts.db.idx files form that PC. you will find those file in the following locations

Windows XP: %userprofile%Local SettingsApplication DataMicrosoftCommunicatorsip_<the_username@the_domain>

Windows Vista/7: %userprofile%AppDataLocalMicrosoftCommunicatorsip_<the_username@the_domain>

4. Restart Lync.
