There was an error while performing this operation IIS 7.5

Faced one new issue while shifting websites from one IDC to AMAZON cloud, I have configured websites as generally we configure and set the application pool also

When I was trying to open any feature from feature panel of that website it was giving error

There was an error while performing this operation in IIS 7.5

The error message was blank so it was very difficult task to identify the error as nothing was getting on net also.

Checked permissions and found permissions were as required so tried to browse the website but here also it was showing below error from which we couldn’t get the exact cause of error

There was no option for getting the exact error code / message which will help to troubleshoot , followed below steps to identify the cause

• Opened Web.config and started removing tags one by one like removed ,
• Still same error
• Removed custom error tag
• Still same error
• Removed
• Error gone away and website started browsing

After checking for the tag details came to know it is for Optimizing Application Initialization Module for IIS and for make website running along with the tag inside web.config we need to install

There was an error while performing this operation web config

Question

Hi I’m getting an error when trying to access a website with standard install of Filemaker Server 13.

I’m on Server 2012. The error message comes up when trying to access any of the panels in IIS.

‘There was an error performing the operation’

Details: Filename \?C:Program FilesSome Pathweb.config

The Error is blank which isn’t very helpful. I have added IIUSR permissions to webconfig.

Going to localhost gives me an additional error code of: 0x8007000d

However the Config Source just says:

So again, that is really unhelpful.

I’ve done a full re-install of IIS including URL Rewrite so I am not sure where to go from here. any suggestions?

Answers

I didn’t manage to fix this other than by installing a brand new version of Server 2012, IIS and FMServer 13 and then everything worked just fine.

Have you tried enabling Failed Request Tracing on the site to see if it gives you any additional hints? Additionally you may want to try reproducing the error while running Process Monitor on the server. That is especially helpful if there is a file access or permissions issue.

Thanks for taking the time to reply Rick.

I can’t enable the Failed Request Tracing as it gives me the error when I click on the icon and then says ‘could not retrieve failed request tracing entries’.

I have installed Process Monitor, but I’m a bit blown away by the detail and not sure what to look for!

Here’s a screenshot of the ‘blank’ error message:

There is a guy who had the same problem here but I have URLRewrite 2.0 installed and I can remove the tags and restart the website, but it doesn’t solve the problem.

That error that you gave a screenshot of is a lot more helpful. First of all, make a backup copy of the web.config at the location that the error gives. Then start removing sections of the web.config one at a time until the page will load. That will help you narrow down which section is causing the error. The link you provided was for someone who was having an issue with the section but it sounds like you are having an issue with a different section that IIS doesn’t like.

Rick, good point — I’m getting tired and not thinking straight. I had renamed the web.config file to webx.config and that gets the server working, but not taken things out section by section / line by line. Just done that quickly — it’s late over here!

The problem is that you have to take out the whole of the section including all the below — which is the whole point of the web.config file to get it to stop returning the error.

Taking out one rule at a time or e.g. the or the doesn’t help — nor does playing around with the syntax. That whole section has to go. Which I think points to something bigger missing in the IIS installation.

Also this was working a week ago, I think until we applied an OpenSSL patch for the heartbleed bug. This was a patch for Filemaker Server 13 but my confusion is that I’ve wiped the whole installation of Filemaker 13 and reinstalled it along with IIS and haven’t installed that patch again, so I should have been left with a clean install as I had previously.

Prevent settings to be overridden by web.config (HTTP Error 500.19)

Two attributes come handy when you need to enforce settings in your hosting environment: overrideModeDefault and allowDefinition . Trying to override settings when these attributes are used may cause users to see HTTP Error 500.19.

Let’s say you don’t want anybody to change the default document. Use overrideModeDefault attribute in the applicationHost.config as the example below.

Looking for a way to ignore web.config files in application subfolders? Check this post out.

HTTP Error 500.19

If an application owner tries to set the default document in a web.config file, this error message will appear:

HTTP Error 500.19 – Internal Server Error
The requested page cannot be accessed because the related configuration data for the page is invalid.

This configuration section cannot be used at this path. This happens when the section is locked at a parent level. Locking is either by default (overrideModeDefault=”Deny”), or set explicitly by a location tag with overrideMode=”Deny” or the legacy allowOverride=”false”.

In this case, if you try to change the default document via IIS Manager, you will receive this error message:

There was an error while performing this operation.
This configuration section cannot be used at this path. This happens when the section is locked at a parent level. Locking is either by default (overrideModeDefault=”Deny”), or set explicitly by a location tag with overrideMode=”Deny” or the legacy allowOverride=”false”.

Choose which configuration files can override settings

If you want to specify which configuration file can edit which tags, use
allowDefinition attribute.

For example, let’s say you want to allow server-level configuration and deny application-level configuration. In your applicationHost.config file:

When an application owner tries to set the default document in a web.config file, the error message below will appear.

Configuration section can only be set in machine.config or root web.config

The reason behind is that we specified MachineToWebRoot in allowDefinition attribute. It means that only machine.config , applicationHost.config , and root web.config file (the one in the same folder as machine.config ) can override this setting.

Here are other values you can use with allowDefinition attribute (Source):

Prevent machine.config to be overridden

For preventing machine.config settings to be overridden by child web.config files, you can use location tag with overrideMode attribute. For example:

Please note that the changes in the machine.config affect all the applications in the web server. So that make sure to test changes in development environment first.

Error “Absolute physical path is not allowed”

One of the error messages 500.19 status code is associated is this: “Absolute physical path is not allowed in system.webServer/httpErrors section in web.config flie. Use relative path instead”. Error code: 0x8007000d

This error is expected when there is an in-place upgrade from 2008 R2 to 2012 R2 because absolute paths are not supported in 2012 R2 and newer versions by default.

In order to solve this error, add allowAbsolutePathsWhenDelegated=”true” to httpErrors section in the applicationHost.config file:

Make sure to reset IIS and test the website after this change.

Question

When I click on Authentication in my Exchange, Exchangeweb, & Public virtual directories I get the above error. I don’t get it on any of the other directories in iis7. How do I fix it?

Complete Error is

There was an error while performing this operation.

Filename: \?C:Program filesMicrosoftExchange ServerV14ClientAccessowaweb.config

Error: Configuration section not allowed to be set below application

Me too. Any ideas on a fix/workaround?

Can I delete web.config safely? (generate new?)

EDIT — Well, I renamed web.config to web.config.nul and this seems to have fixed the problem.

How is the file used? I cannot see any problems as a result of this action yet.

OK, so there is a problem
Runtime Error in «/owa» application.

I know the authentication parameters are correct — they are visible when web.config is nulled. But the client OWA web page does not render.

Is this a known issue?
Does anyone have any more info?

You may try the following.

Steps:

1. Make sure you take backup of IIS7.

2. Goto IIS Manager

3. Right Click on the Virtual Directory ( Ex. «Exchange,» «Exchweb» and «Public») and Choose «Convert to application».

4. Goto Command Prompt

Well, this post is from back in March, so hopefully you’ve figured it out by now. But if someone is searching for this same problem here’s what likely happened.
