Subject Re: How is hostname set?
Date Fri, 28 Dec 2012 09:01:40 GMT
I use the simple networking model.

I use a combination of vbs scripts, cmd and curl. Essentially the script
runs:
ipconfig /all | findstr /C:""DHCP Server"" which gives me the IP address of
the VR in my environment (this will change for each region so can't be
hardcoded). I then use some regular expressions to strip out that IP
address. A curl to http://IPADDRESS/latest/local-hostname will give you the
name that the machine is meant to have. Then all you need to do is run:
netdom renamecomputer localhost /newname:"& newName &" /Force /reboot 30

It's certainly not as elegant as the linux solution and if anyone else has
any ideas I'd love to take them onboard.
