We have two nAppliances that are not fully in production yet, in the process of installing Exchange 2010. Was thinking of using the two nAppliances as two Edge Transports with ForeFront for Exchange with the software load balancing that is included. With that said many people and articles have stated that the Edge Transports cannot be joined to the domain because they will use AD LDS for queries. The one issue that I have come across is that both our TMG nAppliances are joined to the domain and was told by our TMG admin that it is a requirement that they are. Am I at a loss here and forced to virtualize or buy two servers for the Edge? Please advise.
Thanks in advance,
Jordan
