The problem is because the xml file is accessed from the mapped drive. The Standalone mode is able to run successfully because Standalone mode has the local user account used by the 'C1ReportsScheduler' service which can easily access the network locations. But, when the mode is switched to client mode, the network locations are not accessed because the service account that used to access the file might not have the right to access the network location.
Therefore, in order to remove the problem you need to do the following:
- Open 'services.msc' by typing services.msc in run prompt.
- Open the 'C1ReportsScheduler' service properties and change its account to either local account or any domain account which has the rights to access the network locations, i.e. location of mapped drive (N:)
- Restart the service "C1ReportsScheduler."
- Now, in the 'C1ReportsScheduler' window, change the file path to actual network location instead of map drive path. For example, change "N:\SecurityExpirations.xml" to the actual network path, e.g., "\\srv1\\SecurityExpirations.xml."
The error should not occur after this.
