Windows Registry key value changed in different time

Question

Dear Sir,

     Customer has a Windows 2016 active directory using with group policy. He has a problem of Windows registry key value change time to time during computer usage for several hours. The registry value is Proxyoverride.

When the computer startup after login , it has a value :


ProxyOverride value:
*.corp.domain1.com. 192.168.128.124.intranet domain1.com, trusnet:192.168.128.*; autodiscover.domain1.com

After 1-2 hours, ProxyOverride value updated to:


ProxyOverride additional value added in the registry key after a hour:
*.corp.domain1.com. 192.168.128.124.intranet domain1.com, trusnet:192.168.128.*; autodiscover.domain1.com; host1.domain1.com; new-hostvalue.domain1.com

However, Proxyoverride value may switch back to old one after further several hours in the same PC computer.

We try to run command: gpresult /h report.html, both GPO output results are the same.

During operation 1:
