I have had my windows home server model EX470 repaired and the harware inside replaced. I am using the 1.1 version of all the software as that is what came with the unit. My problem is that I am able to do a factory reset and it finishes and says it has to reboot the server. After the reboot the server cannot be found ever again unless I do another factory reset. I have tried other hard drives, I have tried the utility from hp which cannot find the unit either. My router does recognize it just before I start the factory reset but after its completed my router does not see it anymore. I have also tried installing it with just one hard drive in the unit as well as 2. Anyone have any ideas as to a possible solution?
