ADInsight is an LDAP (Light-weight Directory Access Protocol) real-time monitoring tool aimed at troubleshooting Active Directory client applications. Use its detailed tracing of Active Directory client-server communications to solve Windows authentication, Exchange, DNS, and other problems.

ADInsight uses DLL injection techniques to intercept calls that applications make in the Wldap32.dll library, which is the standard library underlying Active Directory APIs such ldap and ADSI. Unlike network monitoring tools, ADInsight intercepts and interprets all client-side APIs, including those that do not result in transmission to a server. ADInsight monitors any process into which it can load it’s tracing DLL, which means that it does not require administrative permissions, however, if run with administrative rights, it will also monitor system processes, including windows services.
