I rarely ever put any code in C:\Inetpub, but some applications will put their websites there by default.
And you may find yourself surprised when, even when using an Administrator account, you don’t have permissions to update files or save files under that location.
Turns out it is an UAC issue. From Thomas Deml, a Program Manager for IIS at Microsoft, in this post:
Here is an easy fix. Run the following command from an elevated command prompt (right click the "command prompt" icon and select "Run as Administrator").
icacls %systemdrive%\inetpub /grant %userdomain%\%username%:(OI)(CI)(F) /grant %userdomain%\%username%:F
Note, do not replace any of the values in between the %% signs, just run it as is. Voila.
No, I don’t know what “(OI)(CI)(F)” means either.
