ProblemCan VERITAS Cluster Server for Windows NT/2000 or VERITAS Storage Foundation (tm) HA 4.x for Windows be installed on a domain controller?
SolutionAlthough it is possible to install VERITAS Cluster Server for Windows NT/2000 or Storage Foundation HA for Windows on a domain controller, this configuration is not recommended. This is particularly true in the case of the Primary Domain Controller (PDC) in a Windows NT domain, or Operations Master (FSMO) roles in a Windows 2000/2003 domain. There are two reasons for this:
1. Domain services impose an increased load on a cluster node, which should be avoided if possible. Applications that Cluster Server clusters, such as Microsoft Exchange Server and Microsoft SQL Server, should be run on dedicated hardware. This is equally applicable in a clustered environment.
2. A cluster node may suddenly become unavailable, either due to failure or during normal Cluster Server operation. In this case, domain services will be rendered inaccessible in a non-graceful manner, which can cause numerous network problems.
