Hi ,
Have you received such error message in Remote Access management console? Or find ACCESS_DENIED or 0xc0000022 in RRAS log?
If yes, service hosts in SVCHOST.EXE are split into separate processes on RS3 and later versions of Windows 10 and Windows Server 2016 and all versions of Windows Server 2019 configured with more than 3.5 GB+ of RAM. Calls to DHCP client API DhcpLeaseIpAddressEx fail with ACCESS_DENIED because the DHCP Client Service process lacks the SeImpersonatePrivilege. Without this privilege, the process can not impersonate credentials.
As a workaround:
Add the SeImpersonatePrivilege to the DHCP client service and restart relevant services:
reg add "HKLM\SYSTEM\CurrentControlSet\Services\Dhcp" /v RequiredPrivileges /d "SeChangeNotifyPrivilege"\0"SeCreateGlobalPrivilege"\0"SeImpersonatePrivilege"\0 /t REG_MULTI_SZ /f
For your reference:
Best Regards,
Candy
