There are times when deploying ADRMS that your install account may not have the appropriate permissions within the domain to create a SCP (Service Connection Point), or during installation your URL is not ready yet.
Microsoft makes available a RMS Administration Tool Kit (download link at end of post). The current version is SP2. This toolkit is essential for troubleshooting and helping you while deploying. Within the toolkit is a utility for registering / unregistering a SCP in your domain. Make sure the account you are using to run the utility has appropriate permissions to create the SCP (Enterprise administrator, or permission to create a container object underneath the Services container)

After running the utility, you can verify that the SCP was created by looking in Active Directory Sites and Services.
