Inventory not loading right

[lukesmith7]

I just installed Spiceworks 2 days ago. I’ve had it scan my IP block and I’ve noticed several inconsistencies that most I’ve been able to fix but what I’m finding interesting is the domain admin account, which is locally on every PC at my company only connected to about 20% of all the PC’s. I can scan and it works just fine. I’ve even gone so far as to test wmi via powershell on the server I installed Spiceworks and I can get the serial but it says in the inventory when I try to rescan it has errors still.

Anyone else seen this issue and know a fix?

Searching the forum would yield you a ton of solutions.

You miss the key detail though, the OS version. (we know it’s windows since you mentioned WMI), but 7, 8, 10 etc

[Rod-IT]

Windows 7 and above with UAC enabled (and this assume you are not using a 3rd party firewall solution).

Run the below on a single troubled machine, then re-scan that one device, if it works you need to apply it to the rest, either manually, script or GPO

netsh advfirewall firewall set rule group="windows management instrumentation (WMI)" new enable=Yes

netsh advfirewall firewall set rule group="remote administration" new enable=yes

netsh advfirewall firewall set rule name="File and Printer Sharing (Echo Request - ICMPv4-In)" new enable=yes

netsh advfirewall firewall set rule name="File and Printer Sharing (Echo Request - ICMPv6-In)" new enable=yes

netsh advfirewall firewall set rule group=”File and Printer Sharing” new enable=Yes

I have been looking through the forums. I haven’t found anything that works yet … hence my post creation. As for the OS type, this is Windows agnostic I have Windows 7 and 10 in my environment and it doesn’t matter. I have devices that successfully pulled and some that haven’t.

I’ve tried disabling the windows firewall completely and it didn’t work. You are correct no 3rd party firewall software.

I have the exact same specs of 2 machine, hardware/software and one works just fine but the other doesn’t.

See above

I just ran these 4 commands. 3 of the 4 stated updating rules … went to scan the device. WMI login works, but nothing found from the inventory.

[Rod-IT]

Do you have UAC enabled?

If so paste the below in to a file, name it Spiceworks.reg or something and run it on that same machine, reboot that device and rescan it

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System] 
"LocalAccountTokenFilterPolicy"=dword:00000001

If you still get errors, please share screenshots

Ok, I added that and rebooted the device. I start the process … I enter the domain admin in. It see’s it fine and starts to rescan.
I see the information for the asset start to try and refresh … After about 5 minutes (roughly) it finally updates.

Then it just goes right back to this.

Not updating anything, unable to pull any information and saying the IP address is offline. I have ICMP from the server to the asset just fine. I can WMIC via PowerShell to the asset also.

[Rod-IT]

Have you ran both the registry file and those WMI filters on the machine, rebooted and rescanned it?

Ping the machine by IP using;

ping -a 192.168.x.x if you get a different machines reply than the one you expect, you need to look at your DNS records

Thanks. This uncovered a bunch of other issues that I’m not surprised is going on within the LAN network. However, it has given me enough to identify what is going on for at least Spiceworks. Thanks.

I would guess that scavenging is not enabled if you are seeing stale or incorrect reverse records.

[lukesmith7]

Surprisingly scavenging is actually enabled. IT stuff is pretty in line, its the asset management and network side that are all over the place. The philosophy before I got here was just get it working, we don’t care how as long as it works. So there would be Server A that plugs into Switch B which plugs into Switch C to get to Server D but Switch B would be routing through Switches Q, R, & S, then Router Y before getting to Switch C … so yeah trying to organize and optimize at any angle I can.
