Hello and thanks for your response,
This is indeed a solution if that were the problem, the thing is the software uninstalled has been completely wiped out of the registry (Uninstall and Install reg keys) and there is literally no trace of it anymore.
Now we've used LSPush manually on the computers and now it does give us information saying it uninstalled the software, leading us to believe its a server issue where Lansweeper is installed on.
What we have noticed with the Connectiontester is that RPC (135) is not open, what we have:
- We have no firewall enabled on the servers and client computers.
- The ports however have been added on both Server and Client (135 RPC/DCOM) because Webroot (our antivirus/firewall) uses that information to open those ports.
- RPC services are enabled.
- WMI does not want to give us any information (RPC unavailable)
We're currently baffled by the "thing" that causes this issue, and are still investigating it on help forums/search engines (WMI and RPC). If you have any insight into this problem please do respond.
Again, thanks for your time.
With kind regards,
Sunny Jansen
EDIT:
The problem has been discovered, after crosschecking devices that did have access and those that didnt some services related to WMI and COM+/DCOM enabled/automatic. Also crosschecked firewall, apparently you also have to add port 135 in Outbound (client computer).
