hosts file locked or deleted from dns cache?
 

I have configured a server with the name and ip address in my hosts file on
my PC. I use windows explorer to put on my desktop icon "property" -
Target: the following command:

//myserver/start/mybat.bat


That works fine, but on some occassions it seems to me that my hosts file
contents simply disappears from my dns cache ( I could not find myserver in
output of ipconfig /displaydns). Of course, when it happens I could not ping
myserver, and I get message something like host unknown.

I do not know what and how something on my PC cause that host file on
c:\windows\system32\drivers\etc\hosts simply does not work as expected.


Can I somehow debug and see what the problems is? Whether some program
locks hosts file or its content is simply deleted?

When I do repair of my local area connection, everything seems to be OK.

The problems is that I have to have admin account to do that.
