Hi,
I'm running a mixed environment, 2 DC's, one Windows 2003 Server the other
Windows 2000 Server with a few other member servers, mixed Windows 2003 and
2000 Servers. My clients are a mix of Windows 2000 Pro's, Windows XP Pro's
and WynTerms.
The problem I'm having is with one laptop w/ docking station running Windows
2000 Pro sp4. Today it gave the user messages indicating that it had a
problem with the network and that the connection to the Exchange server was
lost.
I checked the event log and found the following error recorded 3 times in
just a few minutes:
Event Type: Error
Event Source: Tcpip
Event Category: None
Event ID: 4199
Date: 8/1/2006
Time: 9:58:15 AM
User: N/A
Computer: DON-LAPTOP
Description:
The system detected an address conflict for IP address XXX.XXX.XXX.177 with
the system having network hardware address 00:13:21:F4:84:11. Network
operations on this system may be disrupted as a result.
I tracked down this MAC address to a computer that no one was using this
morning and was not turned on. I checked the DHCP leases and both computers
were listed but didn't have conflicting addresses at all.
Oh, maybe I should mention we are running DHCP on both DC's, each with their
own address range so they don't conflict. (or at least I don't believe they
should)
Any suggestions? I don't even know where to look from here. Could it be
the network card in the docking station is failing? I also checked the
switch where the laptop is plugged in and it was not recording any error
messages either.
Thanks in advance,
Linn
