When you add a new Windows Server device to Serio, you'll be asked for Windows Login details for WMI, and you'll be able to test that WMI can connect to your target server.
If this test fails, you'll receive an error message, which may help you diagnose the problem. If you're still stuck, try working through the following checklist.
1. Starting with the basics, is the Windows Server you're trying to connect to switched on? Can you ping it?
2. Check your credentials. The Windows username and password you supply to connect to WMI must have Administrator rights on the target server. If you're using a domain administrator account, make sure prefix it with the domain name, as in:
3. Is the Remote Procedure Call (RPC) service running on the target server? WMI uses RPC to connect to remote servers. Check that the 'Remote Procedure Call' service is running by looking on the Services panel within Administrative Tools on the Control Panel of the target server.
4. Is the target server Windows 2008? If so, there are a few changes you may need to make to the firewall, DCOM launch and activation privileges, and User Account Control (UAC) settings. It's all explained in this handy Microsoft article:
5. Still stuck? Another option is to bypass WMI altogether and use SNMP to monitor the server with the Serio Inventory Agent.
