100% CPU Usage

[Aquiles Marrero]

Good afternoon,

my server is experiencing 100% CPU Usage. The Process "System". Windows
Server 2003 Enterprise Edition, SP2, 8GB RAM. Roles "All AD Roles" plus File
Server.

240 Users conected.

All users are isolated on VLANs. If You disable all VLANs. The CPU goes down
(of course). Them you start VLAN´s one by one, and CPU goes to 100.

I have applied the instructions on
http://support.microsoft.com/default.aspx/kb/555041/en-us

regards,

Aquiles

You may use process explorer to check the activity of system process.
http://www.microsoft.com/technet/sysinternals/Utilities/ProcessExplorer.mspx

You will want to check the Threads tab of the system process property
