SBS 2011 no network after motherboard replacement
Posted on 2015-02-17
We have a Dell 520r server which we updating with the Dell firmware, driver and bios updarte over the weekend. The lifecycle/Idrac update failed and the server started after the lifecycle controller disabled itself.
This was ok the operating system operated fine but the fans we running at full RPM due to the controller being disabled.
A replacement motherboard was installed by DELL but when the server was restarted there was no network.
ipconfig showed only tunneling, no nics listed. could not access device manager etc as without a network SBS struggles.
We reverted back to the original motherboard and updated chipset and nic drivers. Again the SBS was fully operational.
Went back to the new motherboard but the network issue remained.
Have tried disabling nics, enabling nics, network cable in and out of either or both nics.
Dell are saying its an o/s corruption, as the server runs linux from usB stick!!
Thanks in advance.
