SYMPTOMS

You cannot bring a SQL Server 2000 cluster online if all of the following conditions apply:
  • You have turned on the Force Protocol Encryption option in Server Network Utility.
  • You use the Cluster Administrator tool to bring the cluster server offline and then to request to bring the cluster server back online.
  • Each node of the SQL Server cluster does not have a valid certificate or has no certificate.
The following error messages are written to the Microsoft Windows NT event log and the Microsoft SQL Server error log:
  • Encryption requested but no valid certificate was found.17826 Could not set up Net-Library 'SSNETLIB'SQL Server could not spawn FRunCM thread
Additionally, you cannot use Server Network Utility or the registry to remove the Force Protocol Encryption option.

CAUSE

Server Network Utility needs a connection to the virtual server to remove the Force Protocol Encryption option. Because the virtual server that is running SQL Server cannot come online, you cannot use Server Network Utility to remove the Force Protocol Encryption option. Although the encryption option is stored in the registry, you cannot clear it manually because the cluster's checkpoint file automatically restores the setting.

WORKAROUND

To work around this problem, install a Certificate Server in the same domain as the SQL Server cluster, and request and install a valid certificate on each node of the SQL Server cluster.

STATUS

Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.
