What version of Windows does the hosting company use as well what hosting company are you using?
At the very min the web.config and Uploads folder needs write permission for BugNET to operate properly.
- If the Windows version is 2008 or higher the account that the app-pool for BugNET is running under needs these permissions on the file system.
- If the OS is Windows 2003 or less then the ASP.NET worker account needs those permissions on the file system.
This also depends on who you’re hosting with as some may configure a special account just for your hosting account that everything runs under. It is hard to give you advice
for installing BugNET on a shared hosting account due to the differences each company may implement the hosting.
