Using IIS to establish FTP is simple, but there are many problems. Some minor problems lead to failure to connect to the FTP server, or connection to the server and file download. I have summarized it here. Please put forward errors or incomplete information !! First, make a link. In Windows, how to use IIS to establish an FTP service client to access resources on the FTP server must first be able to communicate with the FTP server (that is, the client can ping the server ). If the customer and the server cannot communicate, how can they access the server? Not to mention downloading resources! Port 21 (ftp port) should also be released on the server firewall ). We should all know that this is not nonsense. After the two conditions are met, let's talk about FTP troubleshooting.I. FTP Server login using an anonymous (iusr_computername: · When accessing the client, it is always on the login page. Clicking login is invalid.Cause 1: The iusr_computername user is disabled on the FTP server. The client cannot connect to the FTP server because the user is logged on to the FTP server and the user is disabled on the server. Solution: enable the user on the server. Method: Right-click my computer and select "manage" to open the "Computer Management" window. Click "local user and group"-"user"-find the "iusr_computername" user, right-click the user, and select attributes to open the "user attribute settings" window. Remove the check box before "Account Disabled. Cause 2: the FTP server sets the IUSR-computername in the Group Policy. The user rejects access to the computer from the network or does not set the IUSR-computername user to access the computer from the network. Solution: remove the policy that the IUSR-computername user rejects access to the computer from the network and set the IUSR-computername user to access the computer from the network. Method: Open the Group Policy Editor-Computer Configuration-Windows Settings-Security Settings-local policy-user permission assignment, and double-click "Deny access to this computer from the network ", find the IUSR-computername user and click Delete. Double-click "Access this computer from the network" and click "add user and group" to add the IUSR-computername user. Cause 3: The isur-computername user password is set incorrectly in the FTP manager. Solution: Modify the isur-computername user password. Make it take effect! Method: Open the FTP site properties and set the isur-computername User Password under the "Security Account" tab. If you forget the password, you can re-allocate the password to the isur-computername user in "Computer Management", and then fill in the modified password in IIS. Reason 4: on the FTP server (ftp site directory) isur-computername user is not authorized to read, used for NTFS partition. Solution: add the isur-computername User read permission to the FTP home directory. Specific Method: Find the FTP site directory on the FTP server, right-click and select properties, and click "add" under "Security tab, to add the isur-computername user and grant the read permission. Cause 5: the FTP manager does not have the permission to read the isur-computername user. Solution: You can add the isur-computername User Read Permission to IIS. Method: Open IIS, right-click the FTP site, select "permission", add "isur-computername user" in the window that appears, and grant the read permission. Cause 6: The number of user connections exceeds the maximum number set to "Limit connections" on the FTP server. Solution: You can set the connection limit to a greater value. Specific Method: Open the FTP site attribute in IIS, and set "connection limit to" greater than "or" unlimited "under the" ftp site "tab ".· Error prompt box: Error 550. After that, you can access the page and stay on the logon page.Cause: the FTP server rejects this IP address and logs on to the FTP site. Solution: Set this IP address as a license in IIS. Specific Method: Open the FTP site properties, select "authorized access" under the "Directory Security" tab, and delete the Client IP address from "excluded" listed below.2. Set it to allow access only after the user name and password are entered. Anonymous access is not allowed.Problem: Create an FTP user and upgrade the user to an Administrator group. As a result, they cannot log on to the FTP server. Cause: Although ftp users belong to the Administrator group, ftp users are anonymous users in windows. Therefore, access is forbidden. Solution: At this time, only new user names are created, such as ftpuser userftp ....Iii. Client Access · An error prompt box is displayed when the file cannot be uploaded upon accessCause 1: only read permission is set in IIS and no write permission is set. Solution: add the write permission to the user in IIS. Method: Open the FTP site properties and check the check box before "write" on the "home directory" tab. Cause 2: By default, anonymous users only have access permissions and do not have the upload permission. You can grant the write permission to the isur-computername user on the IIS manager and the FTP server (ftp site directory. · The file cannot be downloaded when it is accessible, and an error prompt box is displayed.Cause: Download is disabled in security settings of IE.
