The IIS Admin Service allows administration of IIS components such as FTP, application pools, Web sites, Web service extensions, and both Network News Transfer Protocol (NNTP) and Simple Mail Transfer Protocol (SMTP) virtual servers. If you stop or disable this service, you will not be able to run Web, FTP, NNTP, or SMTP sites. Fix: (1) GPO: Computer Configuration\Windows Settings\Security Settings\System Services!IIS Admin Service (2) REG: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\iisadmin!Start
