"Unknown host kairali" problem under windows.

If you are having any problem in which only the "kairali" name is mentioned instead of the full address "kairali.dcs.gla.ac.uk" of the master node. This is due to some problem resolving the host.

(Solution 1, under windows. (thanks to James)).

- Edit the file: "C:\Windows\System32\drivers\etc\hosts"
- And add the line: "kairali              kairali.dcs.gla.ac.uk" (without quotes)
- Now reboot the computer.

Comment 1: This should solve the problem. Although I have experienced it coming back after a while. Rebooting the computer again solves the issue. I know this is not especially convenient, but we haven't found any other fix yet. Try it out, you might be luckier than me.

Comment 2: In my opinion it might be worth it to just use linux when you want to work with the cluster. If your machine is powerful enough you could have a small virtualized copy of linux, that you can use under windows for this purpose.
