I installed SQL Server 2008 RC0 over the weekend. I was expecting a fairly smooth installation, but it ended up taking me most of an evening. First I had to upgrade to Windows Server 2003 R2 SP2 (and had a blue screen occur while halfway through the install!), but that is hardly SQL Server’s fault. I opted to install everything I could, and received some strange error messages (since forwarded onto Microsoft). However, the summary at the end indicated that these problems are only related to full text search, and the rest of SQL Server appears to be functioning normally. The installation application was brilliant, and the debug logging exceptional.
Now to get in and play with it!
