The system prompts "RPC server unavailable" When synchronizing time on the computer system

Today, my colleague told me that her computer time is always several minutes. After adjustment, it won't be OK. Let me see it.

First, I checked that there was no virus in the system, so I wanted to enable automatic synchronization of system time, and found that "automatic synchronization with Internet time server" was gray, that is, unavailable, I checked that the PRC service was started normally, so I was puzzled. First, there was no virus. It may be that other related services or components were not started. Based on the information prompted on the internet, I registered the following components:

At the command prompt(Or run)Enter the following information:

Regsvr32 actxprxy. dll
Regsvr32 shdocvw. dll
Regsvr32 oleaut32.dll
Regsvr32 actxprxy. dll
Regsvr32 mshtml. dll
Regsvr32 msjava. dll
Regsvr32 browseui. dll
Regsvr32 urlmon. dll

 

 

Log out and find that "automatic synchronization with the Internet time server" is available, but an error still appears when you click "Update Now". "PRC service unavailable ", now I think of the "Windows Time" service. It doesn't matter if it doesn't exist in the system service, so at the command prompt(Or run)Input:

W32tm / Register

 

Prompt that the registration is successful, and then start the service

Net start "windows Time "

 

Then click Update now. The synchronization time is successful.
