We've recently got a new Server in. The server has 16Gb of RAM, 8 cpus etc We now have a choice of sticking with Windows 2000 Advanced Server or going with Windows 2003 Enterprise edition. Besides being able to use more RAM and having to use Service pack 3a in Win 2003 Any pros/cons of both ? Any recommendations ? We use Full text, replication, analysis services etc What issues / Enhancements has MS introduced for sp3A ? I know that once Service pack 3A is installed all full text indexes are automatically rebuilt.. Anything else to look out for ?
