1) Make sure that the client is correctly configured (wmi proper access, firewall disabled)
You can use the premium tool "connection tester" for this.
2) Make sure that dcom is enabled on the client (use dcomcnfg : "enable distributed com on this computer")
3) Check dns settings and reverse dns lookup
make sure that the reverse lookup "ping -a ipaddress" resolves to the same hostname as the forward lookup "ping computername"

Another thing you can check and you should be able to do it remotely is this
Start regedit
Look for this key
HKEY_Local_Machine\SOFTWARE\Microsoft\ole
Stringvalue = EnableDCOM
Data = Y
If that is not their then add it and then reboot the computer. This should clear up the issue. I had several pc i had to do this on and it was pretty easy. I just created a kix script to look for that key, if it was not there then it added it and next time the user rebooted the computer Lansweeper was able to pick it up and scan it

The issue I was having was with reverse DNS. Once the reverse dns entries were correct the lansweeper service had no problems scanning the PC.

Would you mind posting that KixStart Script? I am having the RPC issue on most of my computers and they are all remote. Connection and DNS are correct, so I'm assuming it is this. Thanks

I have found that this can occur if there are duplicate entries for either the IP address or hostname of the problem PC on the DNS server. Check the DNS server first in both the forward lookup and reverse lookups for the machine in question. Delete entries that point at the same IP address and make sure the machine name is not referenced twice.

Similar problem. Briefly, We migrated the Lansweeper box to a VM, which went OK. Then upgraded Lansweeper (3.1) to premium and had server performance issues. The old server had been cleaned off and I decided to go back to the physical server. Ran the 3.2 installed, which went well. Now I am getting 95% The RPC server is unavailable. (Exception from HRESULT: 0x800706BA) errors. Before going back to the physical server this wasn't a problem.
Any ideas?

Any ideas? Are your dns settings for the virtual server ok, this might also cause problems.
