Question

If I enable 32bit applications for a site in IIS 8. i get the following error:

500 - Internal server error. There is a problem with the resource you are looking for, and it cannot be displayed.

pl help.

Answer 1

The resolution found to this is to remove the following modules from the iis manager:

1) DynamicCompressionModule 2) StaticCompressionModule

---

To do it follow the below steps in iis manager:

step 1: iis home - modules - unlock these two modules step 2: sites - website home - modules - remove these two modules

---

Now in application pools – select the application pool – Advanced Settings – Change the ‘Enable 32-Bit Applications’ to true

---

This would avoid the internal server error: “500 - Internal server error. There is a problem with the resource you are looking for, and it cannot be displayed.”

To narrow down on the error for finding the specific error; the following should be carried out before the above steps:

In iis manager – Sites – website home – Error pages – Open Feature – select the status code 500 – Edit Feature Settings… - Select Detailed errors and click OK

This would give the detailed error message as below (using it the exact modules that causes the error can be found; earlier we only got the error message: “500 - Internal server error. There is a problem with the resource you are looking for, and it cannot be displayed.”):

HTTP Error 500.19 - Internal Server Error The requested page cannot be accessed because the related configuration data for the page is invalid. Most likely causes: • The worker process is unable to read the applicationhost.config or web.config file. • There is malformed XML in the applicationhost.config or web.config file. • The server cannot access the applicationhost.config or web.config file because of incorrect NTFS permissions. Things you can try: • Look in the event logs for information about why the configuration files are not readable. • Make sure the user identity specified for the application pool, or the authenticated user, has the required permissions to access the web.config file.
