Hi @saha-3843

According to this link: 4625(F): An account failed to log on.
The detailed error message is:
0XC0000192 – “An attempt was made to logon, but the Netlogon service was not started”.
This issue is typically not a security issue but it can be an infrastructure or availability issue.

To me this may not be an issue related to Exchange, but may possibly be related to Windows servers.
Here is a link which may be helpful: numerous 4625 errors in the event log

If currently there isn't any actual issue in your environment, I would recommend ignoring this issue.
