The RPC server is unavailable. (Exception from HRESULT: 0x800706BA)

[joverocker]

I have been going through your forums and have tried every test/tool that has been recommended with no luck. I have 13 machines that this is getting this failure and over 100 that seem to work without an issue.

I can telnet to the machine on port 135 by name, fqdn, and ip.

I have run the tool that you guys have to reinstall the wmi service.

The connection test tool works on the local machine but does not work from the server.

The firewall service has been turned off on the server and client for testing purposes.

DNS has been checked and cleared of any invalid entries or duplicates.

The machine registers with the server however the OS scan is not taking place.

All services have been verified to be running and DCOM services are setup according to your troubleshooting document.

I am open to any suggestions or ideas that you may have.

Yeah the IP addresses are correct, no firewalls in place on either end, connection test tool works on the machine but not from the server...I checked everything listed in other posts and even tried your repair tool for wmi. It is only a handful of machines but I guess I will keep trying to get them to respond or go with a different solution. Thanks

Are the resolved IP addresses correct for these computers?

If yes, there isn't really anything more I can do, this error is clearly related to the workstation not configured correctly.

Could you post the errors that you get in the webinterface after applying the 3.5.1 update. (for the affected client)

[joverocker]

Do you have anything else that you can recommend trying then? The error still remains even after applying the upgrade.

[joverocker]

Do you guys have a trial license to open up the premium features so I can see if it will work for my organization or not?

I did the upgrade per your request and the login script runs, the machine in the web interface shows the green check for RPC, and after a while it goes back to the red X and the same error message from my topic here.

Please mail us for a trial license.
The premium features won't solve this error because it is typical to the scanned computer not configured correctly.

So does that mean unless I upgrade to the premium version there is no solution for the RPC errors I am seeing? How do I know if upgrading will provide me with a fix? I rather not spend the money on an application without knowing if it is going to work or not.

You can install this update without problems. (the steps in the PDF were only necessary if you had the premium version)
