Splunk Web services needs to be rebuilt. In order to rebuild your services, run the following:

1. Make sure Splunkd and Splunk Web are both stopped:
   D:\Program Files\splunk\bin>splunk stop
Splunkweb: Stopped
Splunkd: Stopped


2. Remove the Splunkd and SplunkWeb services:
   D:\Program Files\splunk\bin>splunk disable boot-start
Removing service Splunkd

Removing service Splunkweb

3. Now rebuild splunkd and Splunkweb services:
   D:\Program Files\splunk\bin>splunk enable boot-start
Installing service Splunkd
Service installed
Registering the Python Service Manager...
Installing service Splunkweb

Windows services installed.
Windows services are configured to run at boot.

NOTE:

This will create Splunkd and Splunkweb services with the following properties:

• Startup type = Automatic

Depending on your configuration you will need to make changes to it.
You can make changes in the services console or via the "sc command line program" .

The following instruction is run in the services console:

The following is to make changes using sc command
