The RPC server is unavailable 0x800706BA

[terces]

I finally got lansweeper premium installed on a Windows 2008 Standard x64 Server (database troubles with 64-bit asp.NET), and everything is seemingly working great.

I question that every workstation in our domain, utilizing active scanning, shows the message:

The RPC server is unavailable 0x800706BA

What does the correlate to?

I finally figured this out, I think.

The reason the WMI repair thingie works is simply because it turns off the "Forceware Intelligent Application Manager" service, which is nSvcAppFlt.exe. This is nVidia's built-in firewall, which is installed on any computer using the nVidia chipset, which is a hell of a lot of them.

This is on top of the Windows Firewall. The hidden nVidia firewall defaults to "on" even if Windows Firewall is turned off. IMHO, having multiple firewalls running is stupid and a waste of resources, especially in a corporate LAN environment, but even if you disagree with that, you definitely need to turn it off or reconfigure it in this case.

You can turn it off by going to Start | Programs | NVIDIA Corporation | Network Access Manager | ActiveArmor Firewall. I don't know why this thing has so many different names.

I'll bet if you check, the computers that are having this problem on your network (Lenovos, for instance) have nVIDIA chips, while ones that don't don't. Or perhaps they have some other motherboard chipset firewall installed; I've only found it on computers with motherboards with nVidia chipsets -- in our case ASUS motherboards with AMD processors, but there are others.

Motherboards with nVidia chipsets used to give you the option of installing or not installing Forceware when you load the drivers at initial setup, but it looks like they don't anymore -- they just go ahead and install it.

There's probably a way to configure it to allow Lansweeper to access RPC, WMI, etc. without turning it completely off, but I don't know what it is, nor do I care.

So this script will solve also the RPC error?

No, it will rebuild WMI, other RPC errors are caused by Firewall or network problems.

6) on this page has a script to rebuild WMI on the computer, this might help : http://www.lansweeper.com/kb/accessdenied.aspx

Well, having the same problem and there is no windows FW. It's disabled by our internal policy.
what can be the reason for this RPC error? This is happening just on few computers.

Welcome to Lansweeper!

Windows Firewall is the most likely.
