Agentless WMI Scanning with Fortigate FW in the way

[franko_mc]

Has anyone had success in scanning a Windows target in another network zone protected by a Fortigate FW with NATing rules. Not Lansweeper specific, but I found this article https://forum.fortinet.com/tm.aspx?m=65235 that speaks to what appears to be the same issue I’m having.

In their situation, they ended up disabling the DCE-RPC Session Helper. I need to discuss with my FW admin to see if that’s even option, but wondering if anyone else encountered this and what did you do to resolve.

We have >1000 physical locations behind just as many Fortinet firewalls and have not encountered any issues. We had a large number of tools that interrogate using WMI prior to bringing Lansweeper in, so it's possible we had this as a part of our configuration already.

Thanks for your response. I was able to engage my FW admin and he disabled DCE-RPC Session Helper as per the article I referenced. I'm now scanning without any issues.
