Event ID 1103 DHCP-client

Hello,

I have an Windows 2008 Standard x64 machine. In "system event. log" appear every 10 minutes  events 1103 (source DHCP-client):

Log Name:      System
Source:        Microsoft-Windows-Dhcp-Client
Date:          ....
Event ID:      1103
Task Category: None
Level:         Information
Keywords:      Classic
User:          N/A
Computer:     

Description:
Your computer was successfully assigned an address from the network, and it can now connect to other computers.

Any thoughts on what could be causing this event to appear?

Thank in advance for your help.
