Yes, please do.

@OverFlow, the HWID of the network card was "PCI\VEN_8086&DEV_108C&SUBSYS_02F91014&REV_03\4&6C79FC5&0&00E0: Intel(R) PRO/1000 PM Network Connection".

For now downgrading to 1003 driver pack fixed it issue.

Does anyone else has issues with latest Intel or DriverPack LAN drivers and Intel 1000 PM Desktop Network Adapter? Specifically the ones inside IBM's M52 Desktop PC. The newer models work just fine.
