I've two PE1950 running Windows 2008 server (x64) as domain controllers. Latests firmware updates, Microsoft patches and drivers are installed. No other software on the system.

If I activate Broadcom teaming the system shows regular freezes with the current driver Bcom_LAN_11.0_T4.2_W2K3_8_64_A01.   Each freeze leaves nothing in the event logs. Dell Diagnostics on both systems pass without any problems.  Not using teaming and deactivating one of the NICs seems to solve the problem.

I would greatly appreciate a comment from Dell and a new bug-free driver.
