How can i host multiple dotnet applications??

Hi,
I have hosted asp.net application in an hosting server (aplus.net).
I have placed the web.config file and "bin" folder of the application in WWWROOT .
I have used Forms Authentication by modifying the web.config file as below.
////////////////////////////////////////////////////////////////////////////////////////
<authentication mode="Forms" >
<forms loginUrl="IssueTracking/LogIn.aspx" timeout="15" >
</forms>
</authentication>
//////////////////////////////////////////////////////////////////////////////////////
The site was working fine.

Now i want to host one more dotnet application.
This application also used Forms Authetication. Now how can i use the web.config file??
When i am accessing the new site ("PMS") it is going to OLD Site ("IssueTracking").

If i place a web.config file seperately for each project it is giving me the following error.

/////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
Configuration 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: It is an error to use a section registered as allowDefinition='MachineToApplication' beyond application level. This error can be caused by a virtual directory not being configured as an application in IIS.
Source Error: Line 46: by Microsoft that offers a single logon and core profile services for member sites.

Can any one please suggest me how can i handle this problem.

Each application needs to be placed within its own virtual directory in IIS. Call up your host and talk to them about how to do this - I'm not familiar with how hosting companies do things.

You will need to put each app into a seperate folder, then configure (or have the hosting co. configure) each folder as a seperate virtual directory.
