Enterprise Site Discovery provides a way for an IT Pro to better understand how their users are browsing with Internet Explorer 8, 9, 10, & 11 and discover Web applications that they may not be aware of. This toolkit enables collecting information from Internet Explorer about sites that are visited by Enterprise users. The sites included in this collection can be scoped by zone or domain. This information will help IT Pros prioritize applications, focusing app compatibility testing to facilitate faster upgrades. This is particularly important as customers upgrade to the latest version of Internet Explorer. This feature also provides additional information on how the site is designed and used by Internet Explorer.
Application Request Routing (ARR) is an out of band module available for IIS 7.x and onwards.
ARR enables Web server administrators, hosting providers, and Content Delivery Networks (CDNs) to increase Web application scalability and reliability through rule-based routing, client and host name affinity, load balancing of HTTP server requests, setting up a reverse proxy and distributed disk caching.
This walkthrough will guide you through how to use URL Rewrite Module and Application Request Routing (ARR) to implement a reverse proxy server when the content server is not exposed to the outside world.
Scenario: Consider you have a site with external URL http://www.arr.com and the actual content is hosted on IIS server which is not exposed to the internet world and internal/ intranet URL is http://backendserver/. In this case, we will forward the requests to the ARR server and in turn, internally route it to the backend server.
If you troubleshoot day in and day out, you will deal with an amazing amount of data. Because, to find out the cause and get to the bottom of the issue, we look into lot of places. For example: IIS Logs (If we are troubleshooting issues related to websites hosted in IIS), Windows event logs, Network traces, Custom logs in various formats, Process monitor, Performance monitor, ETW traces, Active directory objects, Registry and what not. In this series of videos, we will discuss about a simple but a powerful tool called LogParser which will help us analyze these log files with tremendous amount of data to troubleshoot variety of issues like slow performance, DOS attacks, session loss etc.
These videos will help anyone who does troubleshooting be it a developer, system admin or end user to effectively analyze various log files.

PHP performance issues are quite challenging to troubleshoot as we don't have any in-built tools that comes with IIS. We could use tools like Windows Debugging tools, Debug Diagnostic or Perfview for any slow response for an applications running in IIS. However for PHP application this may not be helpful.
This Video helps in using various tools like PHP profiler X-debug and WinCacheGrind on troubleshoot slow response issues for PHP application. For this session I'm creating a simple php page named Display.php and time.php that takes 10 seconds to execute. Following is the code snippet
Some of the major resources in the operating system are the physical disk, memory, process, CPU and network. Any of these resources when not utilized properly, will be leading to performance deterioration resulting in process hang or high CPU consumption. Perfmon is a tool to visually display the built-in performance of the operating system by using the counters. Performance related issue is a common scenario for websites hosted in IIS and in this series of videos, we will be exploring how Perfmon can help us in troubleshooting some of them. We will also explore how Perfmon along with Windows debugger, can help us to troubleshoot High CPU related issues, by figuring out the thread ID of the high resource consuming threads and looking into the stack of that. These videos will help anyone who does troubleshooting be it a developer, system admin who wants to troubleshoot issues with websites hosted in IIS.
