I installed FTP server on a windows 2008 R2. I can ping teh port 21. When I access it using localhost name and or IP address on the winodws 2008 r2 server, the logon screen popup, but I can't logon. I have tried the administrator account. For a test, I also added everyone to the FTP folder with full permissions. What could be the problem?Bob Lin, MS-MVP Networking, Internet, Routing, VPN Troubleshooting on http://www.ChicagoTech.net How to Setup Windows, Network, VPN & Remote Access on http://www.howtonetworking.com
