Not able to run profiler

mayank

I am getting following issue while running ANTS performance profiler 8.5

please let me know how can I resolve this.

Error Details from Event log
Application pool RGTestAppPool has been disabled. The request from protocol http to create the application pool failed. Restart the application pool so that Windows Process Activation Service (WAS) can determine the correct state of the protocol. The data field contains the error number.

Thanks for your post and sorry to hear you're running into an issue with the profiler!

There are different reasons that can cause IIS to fail to start, but can I please first check--what operating system are you profiling on? There is known issue where the profiler (versions 8.0 and above IIRC) cannot start sites that have non-http and non-https bindings when profiling on Windows 8 and Windows Server 2012. In case you are running into this, could you kindly open IIS manager, check your bindings for the site you are trying to profile, and try (if only temporarily) remove all bindings except for any http and https (i.e. any net.tcp, net.pipe, net.msmq, msmq.formatname bindings) and then try profiling again?

Should that not help though, can you kindly help try running the profiler explicitly as administrator and then profiling again in case this is permissions-related? You'll need to press shift as you right-click to get the 'run as admin' option. (I realize you may be an administrator on the machine, but UAC may still block some operations if enabled)

Please let me know if either of those helps! We'll keep investigating if not.

I am using Windows Server 2008 R2 Standard with Service Pack 1.

I was able to run ANTS profiler few days back but now I am getting "Web Page cannot be found" on web browser and error logged in event viewer as follows
Error Details from Event log
Application pool RGTestAppPool has been disabled. The request from protocol http to create the application pool failed. Restart the application pool so that Windows Process Activation Service (WAS) can determine the correct state of the protocol. The data field contains the error number.

I dont think this is binding issue since it was working previously on same binding.

I always run it as admin (shift+ right click) so this is also not a cause of this issue.

please let me know if you need any other details.

Many thanks for those details!

Just to confirm, do you get a "Could not start IIS" error when ANTS tries to launch IIS or does the profiler actually launch a browser despite the website not working?

Could you also kindly do a quick check from Task Manager if there are any w3wp processes that may have been leftover from a previous profiling session (and is now preventing IIS from starting properly again), and terminate them if so? If possible, can you also please try restarting IIS?

Thank you!

Thanks Jessica. It is working for me.
