The Exchange server that I had my BES and Exchange 2003 on lost it's RAID partition where the installation and data was stored. I was able to create a new partion (unsable to recover the old) and did a restore of Exchange pri & pub and that works fine as far as I can tell.
I have tried to get BES working but unable since the install folder is gone. I tried reinstalling over top of itself but keep getting the only option listed for the database location as being remote and cant create a new location locally. I have tried uninstalling it through Add/Remove to see if that would resolve but the remote location problem but keep getting Error 1316 a network error occurred while attempting to read from the file c:\windows\installer\blackberry enterprise server.msi.
I have tried deleting folders associated with RIM installation and even tried the keys also - no change.
