I have a win 2003 server running as a DC and it seems that LSASS.EXE stays near 100% cpu utilization.
My problem seems very similar to the older question:
Based on the info from that question I looked at the performance meter and the current bandwidth for the network adapter seems to stay at 100%.
The site is to large to turn off and on computers, but I did look at the LED on the switch for this interface and it does not look as frantic as I expected it to look.
Looking at network packets sent and recieved in the performance meter seems to average 25-30 a sec for each, which does not seem excessive to me.
The machine is a server 2003 standard (SP1) with dual 2.4 GHz xenon and 1 GB ram.
Its only role is DC for a network of less than 150 computers.
The NIC is a gigabit Broadcom, and the second NIC is disabled.
Any thoughts on this appreciated.
