    Intel 82574L loses connectivity

    acraciunescu

      Hello,

       

      I am experiencing problems with a Intel 82574L adapter

      driver version 11.11.43.0

      Intel PROSet version: 16.4.69.0

      Windows Server 2008R2

       

      My adapter loses connectivity a few hours after starting Windows. The network connection in windows doesn't show any changes, the adapter leds keep blinking, but i can't ping anything and nothing can ping me. There isn't any traffic on the adapter. The event viewer in windows doesn't show anything.

      When i run the PROSet diagnostics, the hardware test finds EEPROM Test - failed and Register Test - failed.

      If i restart the server everything works fine, and all the tests pass. The next morning the same thing happens again.

      The server is part of a Twin-blade server, and its twin is configured exactly the same, and has no problems. Both servers have been freshly installed a week ago and there is no other software installed on them, just Windows so there shouldn't be any conflicts.

       

       

      Any suggestions would be greatly appreciated.
