Hi
Today i found that my server can not process updates any more.
When i hit "Update Now" button on Updates page in "Server Options..." im getting error COULDNT_EXTRACT_FILE.

and i realy have no idea of what can become wrong.

Any idea on fix?
Thanks in advance!

UPD:
OS - Win2k8 R2
And lots of updates for OS has been installed

 

I haven't had this specific error myself but in general its a good idea to empty the updfiles folder (and mirror folder) and start a new update from scratch.

You can find the updfiles folder in C:\ProgramData\ESET\ESET Remote Administrator\Server\updfiles (default location W2K8 ). You might need to stop the ERA service before removing those files since some of them might be locked.

/Edit:

Also found a KB article on this: "Why is ESET Remote Administrator Server not updating to the most recent virus signature database?"

 

Thanks for your reply. I have found the solution, but it looks like workaround rather than fix.

1. I have unchecked "Create update mirror" checkbox
2. Deleted folders "mirror" and "updfiles"
3. Updated - it works fine now
4. Re-enabled "Create update mirror" checkbox
5. Updated to recreate mirror
6. It works fine now
