when i scan my network of 20+ computers i get the computer name for the one i im scanning from and ip addresses for the rest, with the error of The true identity of this network device is unknown.
It is possible that a firewall or other configuration issue is preventing Spiceworks from accurately classifying this device. For help in resolving this issue, please read Resolving unknown devices
i have tried turning off the firewalls on both computers and it doesn’t change any thing
1 Spice up
Try the following on one of the problem computers:
- In a command window type in the command:
netsh firewall set service remoteadmin enable
- then go to run in the start menu and run services.msc and make sure that the following services are started and set to automatic:
-remote procedure call (RPC)
ok, wmi performance adapter wasn’t on and is started now. i don’t see wmi driver extensions in the services list. spiceworks is on a windows vista box, the system i have been using to try to resolve the issue is a windows 7 box. both are 64 bit.
Any luck with that. I don’t have wmi driver extensions on my win7 box either. Once I ran this on the win 7 boxes, i was able to see that they were workstations and not unknowns.
it still isn’t pulling up any more then ip addresses for the other computers.
Have you re ran the scan on the device you did the command on? Strange, because I followed the other document and then did the command I posted and it resolved them.
Also have you checked that the following port is open
- **135 (WMI):**Used to detect Windows computers.
Hmmm… What account are you using for the scan, is that account a local admin on all the computers?
Can’t think of any thing else at the moment
its not admin on all the computers but i saw under scanning settings where you can add account types and passwords or is that not right? i added the admin logins there
Have you tried an nslookup to make sure dns is resolving computer names with ip addresses? Maybe try disabling Windows Firewall on one machine and rescan the network to see if it finds it?
what are the steps to do a nslookup? it’s at a small school i am helping out and only there 2 days a week. I did try it with a front office computer and the spiceworks computer firewalls off and didn’t change any thing.
any other things to try when i’m back there tuesday?
Nslookup will let you know if names are being resolved to ip addresses. To run an nslookup, press the Windows key + R at the same time or click start run. Type in cmd for command prompt. Then do nslookup followed by the computer/node that you want to query.
Ex. nslookup computer01
It should return something like this:
Server: server1.test.com
Address: 192.168.1.10
Name: computer01.test.com
Address: 192.1681.30
If it comes up blank with one of these two dns is not resolving correctly. Note, this is for a Active Directory environment.
right now i don’t think theres an active directory setup, i am working with a guy thats over seeing a few schools on getting a domain server set up but as of right now its still off line.
