IssueCannot use Security Analytics 10.3 services with NetWitness Informer
After upgrading to Security Analytics 10.3.x, Informer is no longer able to use the concentrator or broker as a Data Source.
InformerService.log contains the following Exceptions in GetSessionDBRange & RunAlert:
2014-01-14 00:34:16.9740 (InformerUtils) Exception in GetSessionDBRange - SDK indicated an error occurred calling NwSession
2014-01-14 00:34:17.0208 (AlertWorker) Exception in RunAlert - Server must be busy as Informer has received a session ID range of [1,0]. Alerts cannot be run at this time.
2014-01-14 00:35:42.4271 (HandleWatcher) Connection check failed because connect failed with error "a connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond" ... the engine will try to reconnect until a valid connection to a NetWitness data source is made.
2014-01-14 00:35:45.9896 (AgentJob) NetWitness Informer Engine has lost its connection. The service will attempt to reconnect until a valid connection can be made.


The cause is due to a change in the Authentication method.
The workaround is to replace cnwsdk.dll with NetWitness C SDK file (x32 DLL) or later. Attached is DLL from SDK.
1) Download a63918_cnwsdk.zip from this KB article and copy to the filesystem somewhere on the Informer Appliance. Extract a63918_cnwsdk.dll from the zip file and rename file to cnwsdk.dll
2) Stop the NetWitness Informer Service
3) Navigate to the Informer Service directory which is located here C:\Program Files\NetWitness\NetWitness Informer Service
4) Make a backup copy of the current file called cnwsdk.dll
5) Overwrite the cnwsdk.dll with the file downloaded in Step 1
6) Start the Informer service


Download cnwsdk.dll from here: a63918_cnwsdk.zip
