Error messages in update events

Occasionally in automatic updates the event log has these two messages:

Update attempt failed (server connection failure)

or

Function:gethostbyname, parameters: , return value: 11001

What do they mean (at least the second one)?

 

Do you have a wireless connection for your Internet?

There was a problem connecting to an Eset update server. This can be for several reasons... internet trouble, overloaded update server, etc. When this happens, NOD32 will try another server.

There was a trouble in the DNS lookup that translates a ".com" address (u8.eset.com) to a numerical IP address (209.200.224.54). This is usually temporary, caused by a busy DNS server or a bad internet connection.


Basically, both of these errors are the equivalent of typing a good web address into a web browser and not being able to connect, getting a "cannot connect" error message instead. They are usually temporary. Whenever this does happen, NOD32 will simply try the next update server on its list.

Note that if the connection to the second server is successful, you usually do not receive a "yes, I connected" message unless an actual update was performed. This often causes confusion, because most people see the first "bad" connection, but never the second "good" connection right after it.

 

I don't have a wireless connection but a cable one.

Anyway thanks for the explanations of alglove mainly about the second message that I was not understanding until now.

In fact I usually don't have problems updating but the last few days this kind of messages increased in number.

I really don't think this is an issue because if I detect that a new update is available and I don't have it yet I update manually and I never had problems in this kind of update.
