SP4 on SQL Server 2005 Fails 

1. On the active node, use failover cluster manager to pause all passive nodes
2. On the active node, run and complete the SQL 2005 SP4 installation
3. On the active node, use failover cluster manager to resume all previously paused nodes
4. On all passive nodes, run and complete the SQL 2005 SP4 installation using the /passive command line switch
5. Reboot all node

This will ensue that any necessary system databases are updated as well, as opposed to only the binaries. This can be verified using the sql code below:

SELECT SERVERPROPERTY('productversion') as [SQL Version],
SERVERPROPERTY('productlevel') as [level],
SERVERPROPERTY('edition') as edition,
SERVERPROPERTY('resourceversion') as [Resource Version]
