The most common WMI errors

The most common WMI errors

This is only a small overview and we cannot guarantee to offer the solution to your specific problem here, but it’s a start and we will expand this article constantly.


WMI Overload

Probe Health sensor showing a WMI delay

The delay value shows how many WMI requests had to be postponed globally from their intended scanning times. This is indicating an overload problem. A delay of 0% is the most favorable value, if you keep seeing a higher number over a siginificant amount of time you should reduce the total amount of WMI requests on this probe by increasing the scanning intervals of the sensors. Alternatively you can distribute the sensors over one or more additional remote probes.

Note: On Windows 7 you can run about 10,000 WMI sensors with one minute interval under optimal conditions (such as running the core and the target systems exclusively under Windows 2008 R2 and being located within the same LAN segment). Actual performance can be significantly less depending on network topology and WMI health of the target systems – we have seen configurations that could not go beyond 500 sensors (and even less).

Setting Up WMIC Remote Access

Enable DCOM Visual Basic Script

I finally got tired enough of seeing connection problems related to DCOM to do something about it.

Background info: Enabling remote administration is NOT sufficient to allow WMI to connect to a machine. Distributed COM must also be enabled AND configured properly.

So, the attached VBscript will enable DCOM, set the default authentication level, and set the default impersonation level.

Resolving WMI Errors

It will:

1) Rebuild WMI (will give a couple of errors on win7 but will work ok)
2) Setup the firewall
3) Setup DCOM
4) Win7 and Vista disable UAC (requires reboot)

I am working on full win7 support, anything else you would like to see added / changed PM me or leave a comment :-)

Also just to note windows7 will throw errors on the WMI rebuild and DCOM but seems to work…

This is based on the WMI Rebuild script.

WMIRebuild.txt rename to  EnableDCOM.bat

Linux gaming rising: 25 killer PC games that call Linux home

Linux games rising

For the first time in a long time, Linux gamers have a reason to smile. Gaming on the open-source operating system has long meant dabbling in Wine and arcane workarounds, but ever since Valve launched Steam for Linux a year-and-a-half ago the number of native Linux games has positively exploded. Sure, Valve’s embrace of Linux may have a wee bit to do with advancing the Steam Machine ideal, but any game released for “SteamOS” works just fine on other Linux distros, too. Ahead of the big Steam Machine unveiling at GDC 2015, here are a slew of killer PC games that’ve recently become Linux natives.

Images That Brilliantly Capture The Beauty And Horror Of Human Life

Every day we go about our daily lives and routines… pick up a Starbucks, playfully argue with a friend, chat at the water cooler, drive home in traffic, watch the same TV shows, go to sleep. Wake up the next day and do the same thing.

It’s sometimes easy to forget, even after watching the news or traveling to a foreign country, that there is a lot going on in the world outside of our small bubbles of influence. Things both horrifying and beautiful, amazing and sorrowful, positive and negative.

This very first image portrays the problem the Yezidi people are facing. They must protect themselves by all means against the barbaric ISIS militants.

Inhofe’s Insane Climate Denial Speech Proves Republicans Politicians are insane and/or stupid

A few days ago, Republican Senator James Inhofe delivered a speech about why no intelligent person should ever vote for the Republican Party. This was not, obviously, the putative subject of his speech, merely its subtext and inescapable conclusion.

Inhofe tried to make the case that global warming is fake because it is currently very cold. This is not even true. (It is unusually cold in the Eastern United States, but the planet on the whole is having an unusually warm year.) Even if it were true, it would be irrelevant, because the theory of anthropogenic global warming predicts a jagged, long-term rise in temperature, rather than a continuous one. (This year in Washington, D.C., February is colder than January, but it does not refute the general trend for the city to face warmer temperatures in February than January.) Inhofe’s argument was breathtakingly devoid of a factual or logical grasp of its subject matter.

Minority Rules: Why 10 Percent is All You Need

What does it take for an idea to spread from one to many? For a minority opinion to become the majority belief? According to a new study by scientists at the Rensselaer Polytechnic Institute, the answer is 10%. Once 10% of a population is committed to an idea, it’s inevitable that it will eventually become the prevailing opinion of the entire group. The key is to remain committed.

The research was done by scientists at RPI’s Social Cognitive Networks Academic Research Center (SCNARC), and published in the journal Physical Review E. Here’s the abstract:

We show how the prevailing majority opinion in a population can be rapidly reversed by a small fraction p of randomly distributed committed agents who consistently proselytize the opposing opinion and are immune to influence. Specifically, we show that when the committed fraction grows beyond a critical value pc=10%, there is a dramatic decrease in the time Tc taken for the entire population to adopt the committed opinion. In particular, for complete graphs we show that when p<pc, Tc~exp[a(p)N], whereas for p>pc, Tc~lnN. We conclude with simulation results for Erdos-Rényi random graphs and scale-free networks which show qualitatively similar behavior.
