I recently started getting this error:
Description: An error occurred during the processing of a configuration file required to service this request. Please review the specific error details below and modify your configuration file appropriately.
Parser Error Message: An error occurred loading a configuration file: Failed to start monitoring changes to 'H:\2013 T1\SIT302 Project\Deliverables\Website' because the network BIOS command limit has been reached. For more information on this error, please refer to Microsoft knowledge base article 810886. Hosting on a UNC share is not supported for the Windows XP Platform.
Source Error: [No relevant source lines]
Source File: refers back to the web config file Line: 0
I have no idea why this is happening.
The following is contents of my web config file.
<?xml version="1.0"?>
<!--

</appSettings>
<system.web>
<compilation debug="true" targetFramework="4.5" />
<httpRuntime targetFramework="4.5" />
</system.web>
</configuration>
It seems H:\2013 T1\SIT302 Project\Deliverables\Website is a network path not a local path and there is a network problem between the IIS Server and the file server containing the website files. Check the network connectivity.
Users of IIS and ASP.NET often receive this error message when running a website from a network share or NAS device. Check this LINK for more information and the solution.
I made a very detailed answer to this problem here: https://stackoverflow.com/a/20710473/705198
That answer is an accumulation of all the technet, msdn, and blog reference material I could find on the subject, and what we ended up having to do to fix the problem. Disabling Jumbo Frames (HP Server NIC problems causing another error) and SMB2+ combined with the registry edits were what ended up saving us with our high traffic IIS sites. The registry edits alone only made it so the network bios limit errors would not show up as fast under normal load.

I am fresher in ASP.Net C# (4.0). I developed one website and upload to a server. It works in my local system. But when i upload to the server, page displays one error in web.config. AND ERROR IS...
Runtime Error Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine.
Details: To enable the details of this specific error message to be viewable on remote machines, please create a tag within a "web.config" configuration file located in the root directory of the current web application. This tag should then have its "mode" attribute set to "Off".
Your detail is clear enough,To see what caused this error add codes below to your webconfig inside configuration section and then try again
<system.web>
<customErrors mode="Off"/>
</system.web>
I have split my App_Code folder into VB and CS folders, to accommodate the two class files at compile time. I added the following to the web.config file to make it work.
<compilation debug="true" strict="false" explicit="true" defaultLanguage="C#">
<codeSubDirectories>
<clear/>
<add directoryName="VBCode" />
<add directoryName="CSCode" />
</codeSubDirectories>
</compilation>
I now want to remove the two folders and go back to a single vb only... IF I delete the above code from the web.config file I get the following error:
Description: An error occurred during the processing of a configuration file required to service this request. Please review the specific error details below and modify your configuration file appropriately.
Parser Error Message: The code subdirectory '/mysite/App_Code/VBCode/' does not exist.

This is on a hosted site and it appears I don't have access to the machine.config or ability to view it?
How can I go back to previous configuration?
EDIT:
I understand the use of <clear/> but I'm looking to delete the folders from the site... refference: https://msdn.microsoft.com/en-us/library/ms228265(VS.85).aspx

This is my error handling in web.config which is not working.
If there is any exception thrown it doesn't redirect to /Contents/error.aspx page
Is it because I set /Contents/error.aspx -
If not what's wrong with the error handling.
Have you configured the virtual directory as an ASP.NET application for the right framework version?
This error can be caused by a virtual
directory not being configured as an
application in IIS.
In IIS, you can have several applications, but they must be configured as an application. Generally, when you create a web project it maps directly to an IIS application.
Check with your hosting service on how to create an IIS application for your web app.
See IIS Setup
Take a look at here
Try using two '/' in the directory:
//Contents//error.aspx
Hope this helps :)
set customErrors mode="Off" in the web.config to see the actual error. As suggested by Sachin. It turned out to be a compilation Error I had to fix and could enable customErrors again.
On my production server, I just deployed a asp.net web application.
I am seeing a generic '500 internal server error'.
How can I view a detailed error temporarily until I fix the problem?
I already have:
<customErrors mode="Off" defaultRedirect="error.aspx"/>
<customErrors mode="Off" /> is usually enough. But if you have messed up with some IIS configuration it won't even reach your web.config which might explain why you are seeing this generic 500 error message. Take a look at the Event Log (eventvwr.msc) of the server which might contain additional information about the error. There could really be lots of possible reasons (.NET framework misconfiguration, application pool or virtual directory misconfiguration, missing access rights to some folders, ...)
That's the reason why you should have a staging server which has the same configuration as your production server - it would allow you to test your configuration before shipping.
Change IIS Error Pages feature settings to "Detailed errors" or try to run the app from the server where it's deployed.
If the error page is coming from IIS because of some configuration being incorrect, you can try using Failed Request Tracing.
I have developed a web service with the .asmx extension using C# and i want to deploy this into my VPS which has Windows Server 2003 with IIS 6.
Service is running with Framework 4.0 and it's installed in the VPS also. When I upload the precompiled version into the VPS it shows a runtime error
Server Error in '/' Application.

can anyone help me on this?

this is the new error message after enabling debugging in the web.config
You should enable debugging to diagnose the problem.
Microsoft has a very detailed explanation on how to enable detailed debugging over here.
Server Error in '/' Application.
That error is too generic, check the output after you enabled debugging and post the results.
And don't forget to disable debugging after your site goes live.
Update:
Seems to be permission related:
http://forums.iis.net/p/1042369/1454379.aspx
The ASPNET user account needs permissions for the folder that contains your asmx service.
Update2:
You can give the ASPNET user permissions using the file system permission dialog:

Might look different on newer versions of Windows.
From my experience "Server Application Unavailable" means that you have got web sites that use different versions of .net in the same application pool.
the site that hosts your webservice needs to be in an app pool that only has .net 4.0 web sites. The application pool is configured on the Home Directory tab in the web site properties.
Looks to me like the application pool is trying to run two difference versions on .net.
Make a new application pool and call it something like .Net4 and then move the new site across to use this app pool and everything should work.
This error is shown by
Version Information: Microsoft .NET Framework Version:2.0.50727.3053; ASP.NET >Version:2.0.50727.3053
Where the site with a .asmx should say .Microsoft .NET Framework Version:4.0 etc...
