Failed to initialize sqlcmd library with error number -2147467259.

After couple of hours identified that query results using linked server was causing the issue. 

An error occurred during Service Master Key decryption There is no remote user ' ' mapped to local user '(null)' from the remote server ' '. (Microsoft SQL Server, Error: 33094)

To fix this we need to run 

        ALTER SERVICE MASTER KEY FORCE REGENERATE

Once the above command executed linked server started working properly. The dynamic query started to work smoothly, which inturn resolved the issue. 

SSRS not starting - unable to connect to the report server

 After the windows upgrade few cases WMI RS integration will be corrupted, during that time we get the error "Unable to connect to the Report Server "

Solution : 

Based on the SQL Server Version the MOF file will be located in different locations, in our case it was on D drive.

1. Open CMD prompt with elevated privileges

2. Run below command 

mofcomp "D:\SQL Server Files\MSRS13.MSSQLSERVER\Reporting Services\ReportServer\bin\\reportingservices.mof"
