Short description of the error message:
The address of the server is known, but it is not possible to connect to it.

Solution suggestions:
Please check the following - if you are updating:

a. Direct from the Eset's web server

Make sure your internet connection is established.

If you are using firewall, make sure it is set so that it allows NOD32 Control Center (NOD32 CC) to connect to the update server (www.nod32.com, www.esetsoftware.com, sun.uid0.sk, u2.eset.com, u3.eset.com, u4.eset.com, u5.eset.com and u6.eset.com) and must be allowed to download the updates (e.g. for Zone Alarm firewall: in the Programs Tab, for NOD32CC (program) select: "Allow Connect and Allow Server for both Local and Internet").

If you are using proxy server, make sure the parameters to connect to it have been entered in Update->Setup->Advanced dialog window

Make sure you have the correct server listed in the "Location" section. (NOD32 CC->Update->Update->Setup)
