In previous version of Windows, the remote desktop client, mstsc.exe, used to have a yellow tab on top of the screen, viewable when using the RDP connection in full screen. This tab could be fixed to the top of the screen, or minimized when needed. So far, so good. Now imagine this: You're using a Windows Server 2003 or Windows Server 2008, or even a Windows XP Pro machine as an RDP Gateway to other servers/computers on your network. This is a very common usage scenario for many organizations that need to enable remote... [Lire la suite]

My colleague (thanks Kevin), just alerted me to a default setting on ESX 4, which I think is potentially dangerous these days.  If you hit Ctrl-Alt-Del on an ESX 4 console, it will reboot the server even if there are running VMs and it doesn’t care if the server is not in Maintenance Mode. This is an old throwback which most modern Linux distribution disable these days.  To disable this yourself, open up /etc/inittab in your favourite editor and comment out the “ca::ctrlaltdel:/sbin/shutdown -t3 -r now” line with a #...
