Event ID Error 30941:

Initialize failure.

Error code: 80004005

Event ID Error 32175:

Server is being shutdown because fabric pool manager could not complete initial placement of users.

Cause: This can happen if insufficient number of Front-Ends are available in the Pool.

Resolution:

Ensure that all the Front-Ends configured for this Pool are up and running. If multiple Front-Ends have been recently decommissioned, run Reset-CsPoolRegistrarState -ResetType QuorumLossRecovery to enable the Pool to recover from Quorum Loss and make progress.

Event ID Error 32178:

Failed to sync data for Routing group {8EC325CB-B512-587D-9D03-E940E7CC1490} from backup store.

Cause: This may indicate a problem with connectivity to backup database or some unknown product issue.

Resolution:

Event ID Warning 32174:

Server startup is being delayed because fabric pool manager has not finished initial placement of users.

Currently waiting for routing group: {8EC325CB-B512-587D-9D03-E940E7CC1490}.

Number of groups potentially not yet placed: 1.

Total number of groups: 1.

Cause: This is normal during cold-start of a Pool and during server startup.

If you continue to see this message many times, it indicates that insufficient number of Front-Ends are available in the Pool.

Resolution:

During a cold-start of a large Pool it can take upto an hour for the placement process to finish as it needs to populate all the Front-End databases with data from the Backup Store. If the Pool is running and the Front-End is just started, this is normal for some time. If this repeats for a long time, ensure that all the Front-Ends configured for this Pool are up and running. If multiple Front-Ends have been recently decommissioned, run Reset-CsPoolRegistrarState -ResetType QuorumLossRecovery to enable the Pool to recover from Quorum Loss and make progress

You’ve tried using the cmdlet Reset-CsPoolRegistrarState -ResetType QuorumLossRecovery but the front-end service continues to fail to start.

Solution:

Windows Server 2012 is more strict when it comes to trusted certificates and actions such as mistakenly putting an intermediate certificate in the trusted root certificate store can cause replication to stop working between the Edge and front end server. The actual solution is the same as described in one of my previous posts where I faced the similar problem.

Also you may need to add the registry key:

HKLM\System\CurrentControSet\Control\SecurityProviders\Schannel\

create a Key called “ClientAuthTrustMode” and the DWORD Value=2

and reboot the server.
