All my system jobs are in a "waiting" status reason

If you face the same problem here are the solution.

1. First of all you need to make some changes in the MSCRM_CONFIG database. Locate the database and run following scripts:

Update DeploymentProperties SET NVarCharColumn = '<server>:<port>' WHERE ColumnName = 'AsyncSdkRootDomain'
Update DeploymentProperties SET NvarCharColumn = '<server>:<port>' WHERE ColumnName = 'ADSdkRootDomain'
Update DeploymentProperties SET NvarCharColumn = '<server>:<port>' WHERE ColumnName = 'ADWebApplicationRootDomain'


2. Restart the IIS with an iisreset command

3. Restart the CRM Async service

That should do the work!
