I have an error stating that "CMS is not part of cluster" after few days after a successful Installation of IPS .I have checked with the System DSN which is working fine.When the CMS service is connecting to database there has been an error. Please find below hardware and software prerequisites
IPS 4.1 SP4
IPS SP5 Patch
Windows 2012 64 bit
SQL server management studio 2012 32 bit
Databases are created on SQL Server 2008.
Note: Initially the Installation has been successful,after few days the CMS has been down giving the above error.
