Unexpected Error 0x8ffe2740 when starting FTP or IIS

Another one of Microsoft’s descriptive errors is 0x8ffe2740 when trying to start an FTP or Web Server from the IIS Administration module. The error itself means that there is a port conflict with another service. This is a relatively easy diagnosis, as you should already know what ports your ftp or web servers use.

Use the netstat command in the command console to find out what program is using a particular TCP port. Replace the ## with the port you wish to test. This works on Windows Server 2003 and 2008.

The above command will return a PID (process ID). You will need to match that to a running program or service. Type the following command:

Here is an example using port 21. In this example you can see the “ftpsvc” service is using port 21 through svchost.exe – which is normal. In a client’s machine, it was MSUpdate2.exe that was using port 21 – a piece of malware using an FTP server to serve pirated movies!
