we have a AD forest with about 20 sites. each one has a ISA Server 2006 which acts as a proxy server.
i personally dont like that solution,since its a bit overhead to have an ISA Server 2006 on a site with only 3-5 employees.
i personally would have a centralized solution where each site could be administered from.
i also want to replace ISA Server 2006 with something new and more performant.
what could a good solution look-a-like?
