It is possible for a malicious user, to corrupt the Local Security Policy of a Windows 2000 machine which would effectively deny network services. The Local Security Policy identifies: - the domains trusted to authenticate logon attempts. - who may access the system and how (interactively, network, as a service). - who is assigned privileges. - what security auditing is to be performed. - the establishment of default memory quotas. This controls how much paged and non-paged pool an individual may use. If the LSP was successfully corrupted on a Windows 2000 client, a user would not be able to log onto the domain, download files from the server, share files, and so forth. If the the LSP was successfully corrupted on a domain controller, network services would be eliminated throughout the entire domain. In the case that a LSP is corrupted, restoring a well known configuration from backup would be the only solution. It is not required to be an authenticated user in order to mount an...

If the the LSP was successfully corrupted on a domain controller, network services would be eliminated throughout the entire domain. In the case that a LSP is corrupted, restoring a well known configuration from backup would be the only solution. It is not required to be an authenticated user in order to mount an attack. Any remote or local user who can establish a RPC connection and follow a series of specific steps can exploit this vulnerability.
