"Server connection failure" popup message

[ronbar]

I am running NOD32 v2.7 on my Windows 98 PC.

This morning 12/21/2007 a popup that appeared when my PC was booting up;
its title bar was "Update (NOD32)" and its message was "Server
connection failure". I opened NOD32 and tried to do a manual update, and
the same message popped up.

Then I looked at the Event Log. It showed that the last date that the
virus signature database was updated was 12/16/2007. The virus signature
was successfully updated several times before that date; on 12/15,
11/30, 11/29, 11/28, 11/27, 11/26 and 11/25 [Modlue: Kernel-->Event: The
virus signature database has been successfully updated to version {2686
(20071126) thru 2725 (20071216)}.

But I found that there were NO successful Update attempts in the Event
Log. The message [Module: Update-->Event: Update attempt failed (Server
connection failure)] appeared for each of the dates 12/1, 12/15, 12/16,
12/17, 12/18, 12/19, 12/20 and 12/21.

What is wrong? What must I do to stop getting these "Server connection failure" popup messages and allow successful update attempts to occur

Thankful, indeed!
I clicked the link to the FAQ's in your reply and found "Server connection failure", with an "Answer" that included the suggestion that maybe a firewall was blocking the internet connection for NOD32.
I had not made any recent intentional changes to my Lavasoft firewall settings, but I found that NOD32 was NOT included in its list of "Trusted Applications".
So I added 5 files to this list:
From the folder “C:\Program Files\ESET”:
“nod32.exe”, “nod32krn.exe”, “nod32kui.exe”, “nodutils.exe”,
and from the folder “C:\Program Files\ESET\Setup”
“setup.exe”.
After having made the above changes I tried again to update NOD32.
This time the update was successful.
Thank you very much, "Thankful".
