All questions related to installations, configurations and maintenance of Advanced Host Monitor (including additional tools such as RMA for Windows, RMA Manager, Web Servie, RCC).
Could you give more details:
1. What HostMonitor version do you use?
2. What Windows/Service pack do you use?
3. HostMonitor started as Application or Service?
4. What User account is used for Windows Service (services.msc) and in "Service" page of HostMontor Options dialog (local admin, domain admin, BUILt-IN Administrator)?
5. Could you start simplified script for testing:
Could you select "Local system account" on Service page of HostMonitor Options dialog and restart HostMonitor service?
Domain admin account can be specified in services.msc
Please note, these changes may affect test items, performing connections to remote systems without explicity specified credentials.
Could you assign "Replace a process level token" privilege to your domain admin account on the machine, where HostMonitor is running ("Administrative Tools" -> "Local Security Policy" applet -> "Local Policies" -> "User Rights Assignment")?
If this will not help, switching to Local system account on services.msc should work for you.
