Hi, We have 2 Terminal Servers with Windows 2008 R2 and Office 2010 32 bit. The servers have 12 GB of Ram and 4 cores. The TS reboot every 2 days. Some processes take up to 25% (in the case of Excel) or even 50% CPU (in the case of Outlook). While doing so, the process doesn’t use a lot of RAM (20 till 100mb). Needless to say that when this happens, the CPU is often at 100%, slowing the whole TS down. It is difficult to say when the high CPU usage starts. There are error messages about Excel in the eventviewer, but the moment doesn’t correspond to the moment the high CPU usage starts. Also, when closing Excel or Outlook, the process itself sometimes doesn’t stop, but needs to be terminated from the task manager. Any help would be appreciated.
