I have a ACS3.1.1 on W2K with corrupted database. The server is still working though (how could that happen??) Anyway, I was trying to upgrade it but failed. I tried to backup the database and restore on another 3.1.1 server but found the service couldn't start. I'm now stuck. I have hundreds of NAS and thousands of users on the server so I would prefer to import the database. Any advice? Thanks a lot!!
