Unexpected Error 0x8007c801 When You Start the FTP Service (273565)

SYMPTOMS

When you start the File Transport Protocol (FTP) service, you may receive the following error message:

Internet Service Manager: Unexpected error 0x8007c801 occurred

The behavior can occur if one of the following has occured:

The Allow Anonymous Connections check box is not selected and the user name for anonymous access is missing.
Internet Information Services (IIS) has previously been installed without the FTP service, and anonymous access has been disabled from the WWW Service Master Properties. When the FTP service is installed later, it cannot start because the required AnonymousUserName key is not inherited. The FTP Service Master Properties inherits some settings from the WWW Service Master Properties, and because anonymous access has been disabled, the anonymous user account is not inherited. This causes all new FTP sites to fail with the error message above.

Using the Microsoft Management Console (MMC) Internet Service Manager snap-in, open the Internet Information Services (IIS) server snap-in.
Right-click the name of the server, and then click Properties.
In the Master Properties drop-down list, click FTP Service, and then click Edit.
Click the Security Accounts tab.
Select the Allow Anonymous Connections check box and enter a valid user account to use for anonymous access to this resource.
Click Apply to apply the settings.NOTE: If you prefer not to allow anonymous connections, you can clear the Allow Anonymous Connections check box.

You can now start the FTP site without receiving the error.
