Explain network errors in event log?

- WinXP, SP3. NIC: Realtek RTL8139 Family PCI Fast Ethernet.
- Wired to D-Link DI-524, 'AirPlus G' 802.11g 2.4Ghz wireless router
(wireless not used)
- LAN addresses are assigned by the router. (192.168.0.x)
- At the times in question, only this PC is active on the LAN.

Event viewer (system events) shows:

2-3 times per day, one of these records:

" The netcard driver failed the query for OID_GEN_LINK_SPEED. "

or

" Your computer was not able to renew its address from the network
(from the DHCP Server) for the Network Card ...

.... Immediately followed by the record:

" The system detected that network adapter \DEVICE\TCPIP_{..}
was connected to the network, and has initiated normal
operation over thenetwork adapter.


Question: Are these something that needs fixing, or just one of those
"Yeah, it does that" things? I'm not seeing any overt problems
associated with these events.

Thanks.
