Vulnerability from variot

FTP service in IIS 5.0 and earlier allows remote attackers to enumerate Guest accounts in trusted domains by preceding the username with a special sequence of characters. A user attempting to authenticate using a valid login name appended with specially chosen characters, will not be required to specify the domain which the account belongs. Once the account is located, the user will have to complete the authentication process. At this point brute force attacks can be used in an attempt to gain access to the domain
