Event 4625 help - svchost.exe and encrypted user name


  • I am getting tons of these errors everyday for the past weeks, all having the same account name. I tried decoding the name using base64 but it seems that it uses another encryption.  I really do not know what is going on because the process name is ssytem32/svchost.exe which contains manyy other processes and the logon type is using a batch file. i would really appreciate any help on what to look for next.
