SYNOPSIS

SYNTAX

INPUTS

OUTPUTS

System.String

NOTES

The function uses [System.Environment]::MachineName for the short computer name, which works consistently across all platforms where PowerShell runs.

When the FullyQualifiedDomainName switch is used, the function attempts to retrieve the FQDN using [System.Net.Dns]::GetHostByName() which can resolve the full domain name when the system is properly configured with DNS.

If DNS resolution fails or no domain is configured, the function will fall back to returning the short computer name even when FQDN is requested.
