claims that they have either seen (or not seen) many posts that look application pool is being automatically disabled due to a series of failures like theirs, and never any concrete solutions. I am going to try and explain the whole thought process, why iis application pool stops unexpectedly things work the way it does,as well as useful next steps. Question: #1 Our production server has recently started experiencing AppPool crashes. These seem to occur sporadically. sometimes three times a https://www.iis.net/configreference/system.applicationhost/applicationpools/add/failure day, sometimes not for a couple of days. The error manifests itself to the client as "Service Unavailable". In the system event log we see the following:A process serving application pool ‘DefaultAppPool' suffered a fatal communication error with the World Wide Web Publishing Service With error number: 8007006d At the same time (but not always) we see this error in the Application https://blogs.msdn.microsoft.com/david.wang/2005/08/29/howto-understand-and-diagnose-an-application-pool-crash/ Log "Faulting application w3wp.exe, version 6.0.3790.0, faulting module kernel32.dll, version 5.2.3790.0, fault address 0x000249d3" The application does usually start working again after anywhere between 2 and 15 minutes (although no worker process restarts or recycles appear in our perf logs). This problems seems to have started occuring following the latest MS patches being applied to our server. It may just be a coincidence though. We are running Windows Server 2003 Standard. We are about to apply SP1 in an attempt to solve this problem, but I wanted to find out if anyone else has had this problem and what the solution was. I have seen several similarish posts but nothing concrete as a solution. I have seen this article (http://support.microsoft.com/Default.aspx?id=885654) but it doesn't quite match our situation as we are not running as a domain controller. We haven't yet tried running registry monitor as I wanted to find out if error 8007006d always equates to a registry permission problem?? before installing3rd party freeware onto our production server. Any help is much appreciated #2 There is a similar question posted today, but the event ID is differen

I've just installed x86 PRTG on a Server 2008 R2 machine - it didn't have enough RAM for the x64 version. I installed with AutoDiscovery disabled. In my AD domain, I created a service user account which I put into a common Server Admins group. I configured this in the Root Group in PRTG. I picked a server on the network, which happened to be running Server 2008 R2 and IIS 7.5. I checked that the Server Admins group was a member of the local Administrators group on the target server. In 1st group, I clicked Add Device..., entered the device name. selected an icon and selected 'Automatic device identification (detailed, may create many sensors)'. Sensors started to appear. In all, I got 85 sensors! (I can see that the 100 sensors of the free version isn't going to last long!) Most sensors are green. Three are legitimately orange. One is red and I can't see why: App Pool _Total Down Error in Application Pool State: 'Unavailable' It has been up, briefly, apparently: Last Scan: Last Up: Last Down: Uptime: Downtime: Coverage: Sensor Type: Dependency: Interval: ID: 27 s 13 h 8 m 27 s 0.0736% 99.9264% 100% PerfCounter IIS Application Pool Parent every 60 s #2045 The seven actual App Pools are listed and Up/OK. _Total only exists in Perf Mon. apppool iis server2008r2 Created on Nov 12, 2015 7:06:47 PM by sgarratt (0) ●1 Permalink Best Answer Accepted Answer Votes:0 Your Vote: Up Down Hi, I just got feedback from the developer. The _Total Pool should not be added at all as it is only a summarization of all values and therefore has no state itself. So it is safe to delete those sensors querying the _Total Pool. We will change the behaviour in the sof
