Hi, I have a asp.net website deployed inside _vit_bin folder of SharePoint 2007. It works normally good. I want to access the website with different URL. So I added host entry in IIS. It works good in my local VM but in production I was running with issue Server Error in '/_vti_bin/Enfatico/UserManagement' Application. Object reference not set to an instance of an object. Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. Exception Details: System.NullReferenceException: Object reference not set to an instance of an object.

Hi, According to your description, can you make sure that session is enabled from SSP. I have found a good KB link about Enable Session State in SharePoint 2007, please refer to: http://vspug.com/erickraus/2007/12/09/enable-session-state-in-sharepoint-2007/ I hope it can help you a little.
