Troubleshooting mirror update problems

Depending on the method of accessing the mirror folder, various types of problems may occur. In most cases, problems during an update from a mirror server are caused by the following: incorrect specification of the Mirror folder options, incorrect authentication data to the Mirror folder, incorrect configuration on local workstations attempting to download update files from the mirror, or by a combination of the reasons above. Here we give an overview of the most frequent problems which may occur during an update from the mirror:

  • ESET NOD32 Antivirus reports an error connecting to mirror server – likely caused by incorrect specification of the update server (network path to the mirror folder) from which local workstations download updates. To verify the folder, click (windows) Start > Run, insert the folder name and click OK. The contents of the folder should be displayed.
  • ESET NOD32 Antivirus requires a user name and password – likely caused by incorrect entry of authentication data (User name and Password) in the update section. The User name and Password are used to grant access to the update server, from which the program will update itself. Make sure that the authentication data is correct and entered in the correct format. For example, Domain/User name, or Workgroup/User name, plus the corresponding Passwords. If the mirror server is accessible to “Everyone”, please be aware that this does not mean that just any user is granted access. “Everyone” does not mean any unauthorized user, it just means that that the folder is accessible for all domain users. As a result, if the folder is accessible to “Everyone”, a domain user name and password will still need to be entered in the update setup section.
  • ESET NOD32 Antivirus reports an error connecting to the mirror server –communication on the port defined for accessing the HTTP version of the mirror is blocked.
