Not collecting machine information

[Jrobinson]

I've been having problems with Lansweeper since upgrading and finally bit the bullet after not being able to diagnose the error messages I was getting. I blew away sql and lansweeper and did fresh installs. I am still getting information from only about 8% of machines. These are a few of the messages in the error log. They seem to refer to lansweeper31, which isn't installed. All the other message are machine specific versions of these.

I want to add that I am also getting the error The RPC server is unavailable. (Exception from HRESULT: 0x800706BA). Remote access is enabled on the PC's, the firewall is off and my account is a domain admin.

It tests fine using the hostname and IP address but this is whay I get using FQDN. Scan's started with the lsclient work fine also. The product is great by the way. If there was one request, it would be for documentation on how Lansweeper works, especially in an AD environment.

So everything works great except connecting to FQDN names (computer.domain.local)
This is caused by dns problems or incorrect dns configuration on the clients.

lsclient scans back based on Ip address.
Active scanning uses the FQDN name of the computer and resolves this to an IP (this is what's failing in your case)

You can download the connection tester from this thread : http://www.lansweeper.com/forum/yaf_postst251_Client-problems-gt-use-the-connection-tester-first.aspx

Test it first on the affected machine using hostname, FQDN and IP address.

I changed the active scanning back to 0 and the errors have returned

[Jrobinson]

I changed the active scanning value to 0 and most of the problems seem to have cleared up. I still have errors using the action screen even after following the fixes in the forum, but one thing at a time.

Which is the most common error on your clients, is it the RPC error?
When you run the connectiontester, do you see any errors?
