Scanning Errors

[ntoupin]

Hello, we have just got into this product yesterday, currently trying out the trial premium version at a K-12 School District.

Currently we have it running active scanning, one large problem being it found 164 PC's, 28 Servers, but 409 have errors.

Every error for every computer is the same:

Cannot connect to DCOM port 135 : Firewalled? 6/8/2010 9:20:22 AM
The RPC server is unavailable 0x800706BA 6/8/2010 9:20:22 AM

The IP is correct and matches the DNS, we have gone through the "troubleshooting guide"..

http://www.lansweeper.com/kb/The-RPC-server-is-unavailable.aspx

Doing the firewall fix:

call netsh firewall set service RemoteAdmin enable
call netsh firewall add portopening protocol=tcp port=135 name=DCOM_TCP135
call netsh firewall add allowedprogram program=%windir%\system32\wbem\unsecapp.exe name=WMI
call netsh firewall add allowedprogram program=%windir%\system32\dllhost.exe name=Dllhost

seems to remove the first error of "Cannot connect to DCOM port 135 : Firewalled?" which is fine because we can use GP to change the firewall settings to fix that error.


So next we move onto the second error using this guide..
http://www.lansweeper.com/kb/WMI-Access-is-denied.aspx

All services are running correctly, the dcomcnfg is correct for it.

Moving onto the Diagnostic testing.. here's the report:

After that the second error still remains so we went ahead with the VBS script to repair the WMI. This seemed to have fixed whatever the problem was and made the single computer scan-able.

The problem being, we do not want to have to go through this entire process on 400+ PC's.. Is there an easier way to deploy the WMI repair to fix the problem or something remotely?

Thanks.

Another suggestions:
A custom action in lansweeper which uses psexec to run the wmi repair script on a target computer.
This way you can go to the non-working computer in lansweeper and click on the action.

Thought of that also which does sound like a good idea, except the fact that we would have to go to every computer in the list and click the action (not too bad).. is there a way to perform a batch action or select multiple computers and then perform the custom action?

[Hemoco · Accepted solution]

It looks like the default permissions for administrators have been removed.

If you use computer images to deploy it's a common problem is the "base" image has this problem.

I've never tried it but maybe you can run the wmi repair script in a startup script.

It looks like the default permissions for administrators have been removed.

If you use computer images to deploy it's a common problem is the "base" image has this problem.

I've never tried it but maybe you can run the wmi repair script in a startup script.

Sounds reasonable as to the fact that we do clone/image our computers, especially labs.

We thought of running the wmi repair as a startup script however our concern being then how do we ONLY have it be a startup script for computers that aren't working; if there are computers that are both working & not working in terms of the scan, how can we really only have the startup script load for the "broken" ones.. We're not sure whether it matters and if running the wmi repair on a "working" one will in fact harm the computer or interrupt any other computer processes/programs..
