SharePoint 2007 - Central Admin stops working when installing search

On a couple of occasions when going through initial configuration of search- Central Admin stops working - cannot access.
Don't panic - What actually happened in my instances whilst  using Windows 2008 is that if you setup the Search service it writes an entry in its local host file. For example on myServerA we set up appserver to be index server, sharepoint adds following entry to host files


fy80::49e2:5150:a356:32ac%10 myServerA 


What sharepoint is actually doing is reading the Link-local IPv6 Address which is not quite right.


This just needs to be manually replaced in host file 
127.0.0.1 localhost myServerA
