Hi ,

I want my application to be notified when the hostname of the system on which it is running changes. Is there some way to do it in C# ?

I am looking for something similar to NetworkChange.NetworkAddressChanged which will raise an event whenever the IP address of the system changes and hence applications can be notified.

Thanks for the help.

Isn't it necessary to re-start the computer for the hostname change to take effect?

One solution can be this :

Hostname is stored in registry at address :

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\ComputerName\ComputerName

under the key name of ComputerName

Get notified of its changes by this way:

There are also other solutions to watch for registry changes which can be found by Google.

Hope it helps.
