Visual Studio 2010 publish failing with error Unable to add XYZ to the Web site. Access is denied (550).

I started receiving this error when trying to publish through Visual Studio 2010:

Unable to add XYZ to the Web site. Access is denied (550).

The reason being someone had manually FTP-ed files to the website and they had read-only set to true.

Resolution:

Make the folders/files not read-only - easy :)

Umbraco packages throws error installedPackages.config is denied

This was happening on IIS7.5 and the error message said I should add ASPNET account to the security of the file. Instead (as I was using ApplicationPoolIdentity) I removed the Read-Only flag on the packages folder and this fixed my problem.

External hard drive "Access denied" on Windows XP

My computer crashed and I had to re-install the Windows XP Pro OS again. Once it was all installed I tried to access my external hard drive. It poped-up with a message:

E:\ Not accessible
Access denied

My solution was to follow these steps below:

• In Windows explorer click on Tools in the menu
• Select Folder options
• Click the view tab
• Untick "Use simple file sharing (Recommended)"
• Click Ok
• Now right click on the external hard drive
• Select Properties
• Goto the Security tab
• Add your user to the ownership with full permissions

Hope this helps anyone out there!
