Board Links disconnectings

[pepinpepe]

Hi,

We have the same problems with different PCs. The problem is that the ethernet link is disconnected from the network. We don't know why but the effects are always the same:

-There is a red mark in the network icon in Windows XP

-You can only see outgoing broadcast traffic from the PC but nothing incoming from the network

-If you plug the same PC in another port it doesn't recover the connection

-Another PC in the same port as the problematic PC works

-PC is working normally until it is disconnected from the network

Models of boards affected by the problem:

1. Intel(R) 82566DM-2 Gigabit Network Connection
Driver 9.8.20.0

2.. Realtek RTL8168D/8111D(P)
Driver 5.7.14.122.2009 22/01/2009

3.  RTL8168C(P)/8111C(P) PCI E
Driver 5.686.203.2008 3/01/2008

4. Realtek RTL8102E/RTL8103E
Driver 5.7.14.122.2009 22/01/2009

Switches are Procurve 2610 24G with release

R.11.25

In the logs you see.

- Port X is now off-line
- Port X is Blocked by STP
- Port X is now on-line 

 Do anybody know what is happening?

Best Regards.
