Exchange 2013: OutlookMailboxDeeptTestProbe fails with Access Denied

Exchange 2013: OutlookMailboxDeeptTestProbe fails with Access Denied

I recently had an opportunity to work with a customer who was experiencing unexpected database failovers between nodes.  When looking at the ProbeResults log within the ActiveMonitoring crimson event channel the following error event was noted (full event text at end of post):

 

Log Name:      Microsoft-Exchange-ActiveMonitoring/ProbeResult
Source:        Microsoft-Exchange-ActiveMonitoring
Date:          7/8/2013 12:08:31 PM
Event ID:      2
Task Category: Probe result
Level:         Error
Keywords:     
User:          SYSTEM
Computer:      SERVER.domain.com
Description:
Probe result (Name=OutlookMailboxDeepTestProbe/DATABASE)

 

Contained within the event is the following:

 

<Error>Error 0x5 (Access is denied) from ClientAsyncCallState.CheckCompletion: RpcAsyncCompleteCall

 

In the process of troubleshooting we determined that the LMCompatabilityLevel was set to 1.  It should be noted that the default for Windows 2003 is a LMCompatabilityLevel of 2.  When the LMCompatabilityLevel is set to 1 this causes the authentication mechanism that the health service utilizes for these probes to fail.  Due to the number of logon failures to the same database the health service attempts to failover the database to another server to correct the condition.  This does not correct the condition since the issue is domain level authentication and the LMCompatabilityLevel is consistent across all nodes.

 

This issue also impacted the OutlookSelfTestProbe and may result in failure of the RPC Client Access service terminating and restarting.  When setting the LMCompatabilityLevel to 1 this forces the enablement of LanManHash.  This causes the winhttpAutoLogon setting to change to high and no default credentials are sent with requests.

 

Information on LMCompatibilityLevel can be found here:  http://technet.microsoft.com/en-us/library/cc960646.aspx

 

To correct this condition the LMCompatibilityLevel in the registry of the Exchange servers and all domain controllers was changed to 2 – and the servers were rebooted.

  • I am running exchange 2013 sp1 on windows server 2012R2. There is no LMCompatabilityLevel key in the registry. Does that mean i should add it & give it a value of 2? Or does that mean that I have a related by different issue & should leave the registry alone?
