I have been running wireshark on my network to see why the users are having “hic ups” when it comes to accessing server resources.
What I found baffeled me…
The sever has 2 nics. One is not even in use.
00 19 b9 b3 cc 7a
00 19 b9 b3 cc 7c < not in use
When the client lose access to resouces (which last about a minute) Wireshark shows a third MAC adress comming from my server with a duplicate IP of the server!
00 19 b9 b3 cc 7e <- MAC adress that is causing the problems..
Anyone have ANY idea what is going on?
Specs:
Sever Model: Dell Poweredge 2950
Nic: Broadcom BCM5708c NetXtreme II GigE (updates drivers still same problem)
OS: W2k3
