Remote Desktop Gateway Causes ESENT 490 Errors on Server 2012 R2 Essentials

On every restart of a new Windows Server 2012 R2 Essentials machine, I get several instances of the following errors in the Application event log:

Log Name:      Application
Source:        ESENT
Event ID:      490
Level:         Error
Description:
svchost (3536) An attempt to open the file "C:\Windows\system32\LogFiles\Sum\Api.chk" for read / write access failed with system error 5 (0x00000005): "Access is denied. ".  The open file operation will fail with error -1032 (0xfffffbf8).

Level:         Error
Description:
svchost (3536) An attempt to open the file "C:\Windows\system32\LogFiles\Sum\SystemIdentity.mdb" for read / write access failed with system error 5 (0x00000005): "Access is denied. ".  The open file operation will fail with error -1032 (0xfffffbf8).

MSKB 2811566 and this Connect bug discuss SQL Server causing this issue. But the error says it’s coming from svchost (3536). Using Sysinternals Process Explorer, I learned that this PID is actually hosting the Remote Desktop Gateway service. I confirmed this by stopping and starting that service; the errors repeated.

Workaround

The Remote Desktop Gateway service runs using the Network Service account. Once I gave that account Modify permissions on

C:\Windows\system32\LogFiles\Sum

the ESENT 490 errors stopped. Instead, I get these messages when starting the Remote Desktop Gateway service:
