Steps to Reproduce and Observed Behavior

On windows while opening \\server file, zig return unexpected status.
error.Unexpected NTSTATUS=0xc0000039

Though when opening \\server\... im getting error.NetworkNotFound as expected.

_ = try std.fs.cwd().openFile("\\server\", .{}); // error.Unexpected NTSTATUS=0xc0000039
_ = try std.fs.cwd().openFile("\\server\a", .{}); // error.NetworkNotFound

Expected Behavior

Expected to get back a valid error, like error.BadPathName or error.NetworkNotFound.

It seems to happen too, when opening files with invalid paths like: \\\\.
