Apparently due to a active directory error, Exchange is not auto replaceing the .edb and .stm files when I rename them and re-boot. I need to manually force creation of a empy copy of the file. I do not need the data from the origional. How do I get exchange 5.5 to build the file? The exchange data base was partishioned into several segments. This is just one of the 4 segments. Note this is the small business server version of exchange.
