The Microsoft Exchange Service Host service (Microsoft.Exchange.ServiceHost.exe) on a computer that is running Microsoft Exchange Server 2013 crashes after you enable United States Federal Information Processing Standard (FIPS) compliant algorithms for encryption, hashing, and signing.

In this situation, after your server runs continuously for several hours or several days, you notice that the Network Store Interface (NSI) service leaks memory. Additionally, you notice the following symptoms: If you stop the monitoring software, the memory leak stops.

When critical Windows system files are missing or corrupted, your operating system may begin to malfunction. Common symptoms include Windows features not working properly, system errors, or Windows becoming unresponsive or freezing.

On a computer that is running Windows Server 2008 R2 or Windows 7, the Svchost.exe process that hosts Windows Management Instrumentation (WMI) service may crash.

After you install the Microsoft Exchange Server March 2022 security update, the Exchange Service Host service (MSExchangeServiceHost) fails repeatedly and logs Event ID 7031 in the system log and Event ID 4999 in the application log:

Fixes an issue in which the Svchost.exe process that hosts the network location awareness service crashes in Windows 7 or in Windows Server 2008 R2.

Fixes an issue in which an Svchost.exe process crashes in Windows 8 or Windows Server 2012. This issue occurs when the process hosts a Group Policy client service that tries to apply a policy.

In this scenario, if you resume the setup process after you fix the issue, Setup fails and returns a "Could not start MS Exchange Service host service" error message. This occurs because the service is in a Disabled state. To fix this issue, install Cumulative Update 13 or a later cumulative update for Exchange Server 2019.

Fixes an issue in which Event ID 4999 is logged when the Microsoft.Exchange.ServiceHost.exe process on an Exchange Server 2010 server crashes.
