Error of application log

[Guest]

This server have a backup process every day, by in this few weeks, it have
error 'System can't determine the computer name or user, return value 14.'
form in the application error and make the dhcp and dns can't work, and it
make the backup process can't backup some data, when the error form, it must
need to reboot the server to solve, but the error always form at the
mid-night to morning, about twice in a week, in between each five minutes.

Does anybody know how to solve this error without reboot the server?

If anyone can solve that, please help me...

Hi David,

I'm by no means an expert in User Profiles or USERENV Logging, but if
you're getting the following event in the Application Event Log:

Event ID: 1000

Category: None

Source: Userenv

Type: Error

User: NT Authority\System

Computer: The domain controller

Description: Windows cannot determine the user or computer name. Return
value (14).

Then you may need to enble enable USERENV Logging as outlined in article ID
221833 and/or dump out the memory.

We have found in past cases through debugging a memory dump, that
Symevent.sys installed on a servers was responsible for a 64MB non-paged
pool memory leak consumption over a period of 4 days. Disabling this
anti-virus filter driver resolved the customer's issue.
