Here are some steps to help troubleshoot this. Some of this you have already done but this covers most situations.
Also, if this is an XP machine make sure simple file sharing is disabled. (see how below)
- Verify you can currently ping the machine by name from the EminentWare Server.
- Verify that the account specified in the error is an admin on that machine
- Verify that you can connect to that machine's admin$ (with the user specified in the error) using net use Z: \\machinename\admin$ /user:domain\username password
- Verify that you can make a WMI Connection to the machine using wbemtest
From the EminentWare Server machine:
- From run or from a command prompt launch wbemtest.exe
- Click on the Connect button
- Edit the default path with \\machinename\root\default
- Supply the credentials used in the EminentWare credential ring (also in the error message) to connect to that client
- Click Connect.
If you are unable to connect using wbemtest:
- This could be that the Firewall is blocking WMI
- This could be because dcom is disabled on that client machine
Check the firewall on the client machine:
- If allowed by company policy you may also want to completely disable the firewall for testing purposes.
- You will need to necessary ports open as outlined in this document EminentWare Components, Communications, and Required Ports
To check that DCOM in enabled - From the client machine:
- Launch dcomcnfg from run or from a command prompt
- On Windows7 - Under Console Root -> Component Services -> Computers right click on my computer and choose properties
- Check on the Default Properties Tab and make sure Enable Distributed COM is checked.
