Plus some others I've seen mentioned in various articles:ĭNS and DHCP are setup correctly (with scavenging) and PC names and IP addresses correctly resolve back and forth. #The rpc server is unavailable lansweeper windows* Windows Remote Management (WS-Management) I believe all the required services are running: We use Kaspersky AntiVirus but again this makes no difference as I can disable it, or remove it, and it makes no difference. I believe all the recommended ports are open but again this isn't seemingly relevant as turning off the firewall (at both ends) makes no difference. I've re-written the entire Domain Windows firewall policies (and used 'gpupdate /force') so they're cleaner and so that I can turn off specific ones for testing. I can COMPMGMT.MSC to a remote PC and view Windows Logs, start/stop Services and use Performance Monitor but I cannot use WMI Control ("Failed to connect to \\ because "Win32: The RPC server is unavailable.") Lansweeper and SpiceWorks running on the same server, virtualised Windows 2012, but this isn't really relevant as any two machines cannot RPC/WMI to each other. #The rpc server is unavailable lansweeper windows 7Currently I have 6 out of 110 machines that I can scan, plus all the servers.Įnvironment: Windows 7 pro, all PCs on the same LAN subnet (255.255.255.0) and on the same Domain. Our machines did scan using both LanSweeper and SpiceWorks until January and then it seems that over a two week period (12th-28th) they all stopped being scannable. Which returns "The RPC server is unavailable." It does work if I run it locally (just to prove WMI is running.) Note that I put quotes around and as they contain non-alphanumeric characters. Wmic /node:"" /user: /password:"" cpu get maxclockspeed I'm testing with the LanSweeper "TestConnection" program (only for paid-up users I believe) and it's failing on the "Scanning WMI" section, returning 3 x "The RPC server is unavailable" errors. I do confess the Microsoft technet article (4494) at the top of Google goes beyond my understanding as I'm not familiar with network tracing. I'm getting the dreaded "RPC server unavailable" error and I've tried every fix on the first 3 pages of Google and also all the posts and recommendations on the LanSweeper website and forums. I'm getting nowhere and I'm hoping someone can prove that I'm an idiot and have missed something obvious.įorgive the length of this post but I'm going to try to give as much information as possible upfront. However after a week with no successful responses I'm re-posting here:Īfter 6 weeks occasional tinkering, and now three days solid work, I'm finally throwing in the towel and conceding defeat. 16:30:38.I posted this originally in the SpiceWorks forum as the error isn't solely related to Lansweeper.
