Event ID 51 and CounterSpy

By Space Coyote ·
I was having several Event 51's on my CounterSpy server and could also not connect to any of my clients after migrating this server to VMware. I followed the following help I received from http://www.hardwareanalysis.com/content/topic/12946/?o=280 I cleared the event 51's and resolved CounterSpy's issue contacting its clients:


To change the registry settings for prefetching, start the Registry Editor by selecting Run from the Start menu, typing regedit in the Open text box, and clicking OK. When the Registry Editor window opens, navigate through the left pane until you get to this hive:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\PrefetchParameters

In the right pane, look for the key named EnablePrefetcher. The value of this key represents how prefetch works on your system. Values you can choose from include:
0?Disable
1?Application Launch Prefetch
2?Boot Prefetch
3?Prefetch everything

To change the value, double-click it. You'll then see the Edit DWORD Value screen. Enter the value representing the level of prefetching you want in the Value Data field.

As a general rule, if you're on a low-memory workstation, 128 MB or so, set the value to 0. If your workstation has 512 MB of RAM or more, set it to 3. Otherwise, you can choose the value as best suits your needs and observations.
