IIS FTP Server works locally, but cannot connect from remote

ftpiisiis-7windows-server-2008

I'm trying to setup an FTP server on Windows 2008 Server. I can connect locally:

C:\>ftp localhost
Connected to WebHead1
220 Microsoft FTP Service

However, when I try to connect from remote, it doesn't work:

~>ftp x.x.x.x
ftp: Can't connect to `x.x.x.x': Operation timed out
ftp: Can't connect to `x.x.x.x'

I've tried everything I can think of with the settings. The FTP server is bound to all unassigned IPs and listening on port 21. I've also checked "FTP Server" in the firewall settings. Nothing appears in the FTP log files. I'm totally out of ideas!

Figured it out. The issue is documented here.

Basically, you have to run:

sc sidtype ftpsvc unrestricted

And then restart the FTP service:

net stop ftpsvc & net start ftpsvc

From what I can tell, it's a bug in R2. Go figure.
