"The specified user name and password cannot be used to log on to the FTP server" SOLUTION

During the past few days, the FTP runtime environment is always unsuccessful. After the site is successfully established, enter the FTP address in the browser, but a prompt box is displayed.

No matter how many times you enter the correct user name and password, even if you enter the original Super management password, you still cannot connect to the server. At first, I thought that my IIS 6.0 was not properly installed. It may be that the FTP isolation user component was not correctly installed. Later, I ruled out this possibility. The final reason is,It turns out that I chose the "isolated user mode" every time I set up an FTP site, while IIS 6.0 has a specific requirement on the isolated user site configuration, that is, you must create a subdirectory named "localuser" under the FTP root directory, and create n subdirectories under this "localuser" subdirectory, in addition, the names of the n sub-directories must be exactly the same as the existing n users in the computer. Otherwise, even if a site is created, the connection will fail, as shown in the preceding figure.

For example, we have created an FTP site called "webftp". the root directory of the site points to the "Web" folder of the d disk. To create an FTP site in isolated user mode, follow these steps:

First, create a directory named "localuser" under the "D:/Web" Directory (Remember, the name must be "localuser ").

Step 2: Create n sub-directories under the "localuser" directory. Assume that the sub-directories are named "user1", "user2"... "usern ".

Step 3: Go to computer management and add users or user groups. Add n users. The usernames are "user1" and "user2" in sequence "... "usern" must correspond to the names of the n sub-directories created in step 2. (You can also create an ftpuser group and put the N users in the ftpuser group, finally, for the sake of security, do not forget to delete all the users you just added from the users group ).

Step 4: Open your browser and enter ftp: // your IP address, for example:FTP: // 192.168.11.3In the displayed dialog box, enter the user name and password.

After the above four steps, the isolated FTP site can run.

If you think this is troublesome, do not select the Isolation Mode in the new site wizard. In this way, you can directly link to the FTP server.
