If this is the case, be careful not to end up with two different instances of the same file when making changes. Quit, or continue with caution. (2) An edit session for this file crashed. If this is the case, use ":recover" or "vim -r /etc/resolv.conf" to recover the changes (see ":help recovery"). If you did this already, delete the swap file "/run/resolvconf/.resolv.conf.swp" to avoid this message.

  • NOTE: Use 64bit editor ( Notepad2 x64 ) to change 64bit asp.net application's "applicationHost.config" !!

    No Comments

    1. If current windows OS is 64bit ( win7 x64 or windows server 2008 ) , then 32bit editors ( notepad++ , visual studio ) can't actually change C:\Windows\System32\inetsrv\Config\applicationHost.config ; changing this file is actually changing C:\Windows\SystemWOW64\inetsrv\Config\applicationHost.config, which is configured for 32bit asp.net applications on 64bit OS platform ! 2. So, to serve 64bit asp.net application we need access real "C:\Windows\System32\inetsrv\Config\applicationHost.config" , then we need a 64bit editor. "Notepad2 x64" is an ideal choice.
