Problem with Environment.Mac hineName

Ely
When I call the Environment.Mac hinename to try to get the local machines
name, I get a "Object reference not set to an instance of an object" error.
This same code works fine on my local machine, it just started having
problems when i rolled it out to a production machine.

Thanks

Hi,

Maybe your ASP.NET account doesn't have permission to read environment
variables. Refer to:

This was from a windows service, not asp.net.

However, I did find the answer to my problem. The computer had netbios
disabled. Once I re-enabled netbios, the command worked fine.

Thanks for the response.

Hello, I have created a a logging mechanism, that writes mesages to a custom event log. On each check it verifies whether the requested source is registered to the "IPS" log. If not, it changes the registration. My problem is that *some* messages still goto the application log, even with this code. I have stepped through the code and verified that the logName variable actually contains the value "IPS", but it still does not go into my...

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not.
