Could not update virus signature

Hi,

We are using the network-based NOD32 anti-virus which the client computers are connected to the local Remote Administration Server to update the virus signature.

But, since yesterday, the client computers cannot retrieved the latest virus signature from the server, it keeps on prompt the message with "could not updated the virus signature", "cannot connected to the server".

However, the remote administrator server is working properly when updating the latest virus signature.

Please help.

Thanks in advance.

 

in the workstation try ping the server
open de brower and check with http is correct: http://IP_YOUR_SERVER:2221/update.ver
