Is setting up FTP in IIS really so weak?

Is setting up FTP in IIS really so weak? IIS is actually very strong, but Chinese people will not use it.
Win2000
It is impossible to create a domain, Microsoft's things, But It emphasizes a complete set of solutions. (The Word is strong, but the terrible thing is not the Word, but the OFFICE. What's even more terrible is that they are all under Windows. behind them, there is also a set of Visual Studio and countless fans, this is what makes Microsoft terrible and terrible)
The level of user management increases. The so-called security is guaranteed by the security settings of the domain. I don't think you have any objection to the operations of Domain Users.
Server is not available. The core of Win2000 is Server, and IIS is also Server. The Pro version of IIS is weak, so do not compare it with other FTP.
As for user groups, access permissions are all integrated in NFTS. If IIS imposes additional restrictions, it seems redundant. (otherwise, the configuration will be really awkward, as you can imagine) to make full use of the NTFS feature, this is clearly stated in IIS. when you look at the attribute, an NTFS will pop up. sometimes, pages cannot be opened because NTFS is not configured properly during Web Services.
As for expansion, ServerU provides interfaces that allow third-party software development. IIS is based on the COM technology and can directly call the service control IIS, whether it is an application or script. it is very convenient.

Microsoft's technology is often highly dependent on each other. Microsoft's analysts and architects have built almost perfect frameworks. 1 + 1> 2 So 1 + 1 + 1 =?
There are two main reasons for the low usage in foreign countries.
A large company uses a lot of Unix, while Win2000S or AS costs are too high, response talents are less than Linux Unix. ServU is relatively cheaper, and no professional staff is needed
2. Other Windows vulnerabilities. Because Windows is popular, it is more vulnerable to attacks, which puts too much pressure on IIS. After all, IIS is often used as a WEB server, which is inevitable.
Piracy is prevalent in China, but Win2kAS + domain is not available on any machine. there are fewer people who have studied the study. Although there are a lot of MSCE in China, there are not many serious studies. of course, Chinese people are also part of the cloud. the psychological shadows of iis web services are also transferred to FTP.
To be honest, as long as the configuration is complete, Windows is actually very secure, and iis ftp is actually not weak. If you say ServU, how long will it take to get down?
