I have begun upgrading My SQL Servers. I have 2 servers that are in a Active/passive Cluster. The current operating system is Windows NT 4 Ent.Ed. I started to upgrade the secondary node to Windows 2000 Adv. Server. When I completed the upgrade, everything would fail over except the Sql Server service. How do I correct this. Also does anyone have a link to reliable step by step instructions on how I should handle Upgrading my SQL 7 Active/Passive Cluster to SQL 2000 and Windows NT 4 Ent. Ed. to 2000 Advance Server?? Thanks in Advance!!
