Hello,

it's about two Intel Xeon Processors with HyperThreading
Technology. After I installed Windows Advanced Server I
sow 4 Processors in Windows Task Manager. At once (system
worked without changes) server was shutdown, and after
that I sow in Task Manager 2 Processors.

Does somebody know something about this?

Thanks for time,
Keli

Hyper-threading causes Task Manager to show double the number of processors.
Somehow, Hyper-threading got turned off if it is only showing 2 processors (or a
uni-processor HAL got installed.
