IIS 7.5 Windows Server 2008 R2: Access Denied Permissions

I'll just be short about this error. New to IIS 7.5 Windows Server 2008 R2 and have issues with permissions write access on folders that the application is using?

Write Access to folders will not cut it by simply giving permissions to IUSR or IIS_IUSRS group.

If the application pool is using “ApplicationPoolIdentity” this means that the application pool has its own user account.

You need to add the App Pool use to that folder and give it access.

The transaction manager has disabled its support for remote/network transactions. (Exception from HRESULT: 0x8004D024)

In .Net this exception occurs when using the TransactionScope.


using (TransactionScope ts = new TransactionScope())
{

}


Follow this instructions on all database servers and web servers to configure properly the MSDTC service.

First verify the "Distribute Transaction Coordinator" Service is
running on both database server computer and client computers
1. Go to "Administrative Tools > Services"
2. Turn on the "Distribute Transaction Coordinator" Service if it is not running

If it is running and client application is not on the same computer as
the database server, on the computer running database server
1. Go to "Administrative Tools > Component Services"
2. On the left navigation tree, go to "Component Services > Computers
> My Computer" (you may need to double click and wait as some nodes
need time to expand)
3. Right click on "My Computer", select "Properties"
4. Select "MSDTC" tab
5. Click "Security Configuration"
6. Make sure you check "Network DTC Access", "Allow Remote Client",
"Allow Inbound/Outbound", "Enable TIP" (Not required if the client machine and remote machines are in the same domain)
7. The MSDTC service will restart.

On the client computer use the same above procedure to open the
"Security Configuration" setting, make sure you check "Network DTC
Access", "Allow Inbound/Outbound" option, restart service and computer
if necessary.

On the SQL server service manager, click "Service" dropdown, select
"Distribute Transaction Coordinator", it should be also running on
the SQL server computer.


Is this does not solve the issue, check the web server to ensure if DTC is enable.
1) Go To Control Panel
2) Add Remove Programs -> Add/Remove Windows Components
4) Select the Application Server and Click on the Details button
5) Ensure that Enable DTC Service is selected.

IIS Error: You have attempted to execute a CGI, ISAPI..

I setup a new asp.net 2.0 application under IIS web service and I come across this error:

The page cannot be displayed
You have attempted to execute a CGI, ISAPI, or other executable program from a directory that does not allow programs to be executed.


When you get this error it usually means that you have not set execute permissions to "Scripts only" under the "home directory" tab in your website properties. When creating a new website the value for execute permission is set to "none". Changing to "Scripts only" will solve this problem.

IIS 5.1 Server Application Unavailable Error

I get this error sometimes when I change the default application in IIS.
When trying to browse my default.aspx page I get the big red font error "Server Application Unavailable".

I fix this issue by executing the following commands:
1) Give modify access to the "IIS_WPG"and "Internet Guest Account" users to your web directory. Try see if that works, if not continue with step2.

2) aspnet_regiis -i
3) iisreset

Microsoft Instructions:
To fix IIS mappings for ASP.NET, run the aspnet_regiis.exe utility:
1. Click Start, and then click Run.
2. In the Open text box, type cmd, and then press ENTER.
3. At the command prompt, type the following, and then press ENTER:
"%windir%\Microsoft.NET\Framework\version\aspnet_regiis.exe" -i
In this path, version represents the version number of the .NET Framework that you installed on your server. You must replace this placeholder with the actual version number when you type the command.

Then,

1. Click Start, and then click Run.
2. In the Open text box, type iisreset.

Done! Go check out your site it should be up and running.
