The fault server is SQLServer2000. The phenomenon is normal for the query analyzer, and the enterprise manager is all normal in addition to the other. Unable to solve it within a limited time. Reinstall the genuine SQLServer several times (registry has been cleaned up) can also solve the problem. I have to reinstall the system. Procedure as follows:
1. The CMOS mask IDE hard drive is invalid. Result in the RAID disk error. Only power supply
2. The RAID card driver does not press F6 installation when Windows 2000 is installed. Unable to identify RAID partitions
3. The original role and login cannot correspond to the database restore
