All but 5 machines throwing RPC unavailable

[ja3hawk]

When I run the test connection on these machines, all 4 tests come back ok

checked DNS and it appears to be fine

firewalls are turned off via group policy

file and printer sharing is enabled, simple file sharing is turned off

I have tried several things and am posting as a last resort. Thanks in advance.

Yes this was with active scanning. I've figured out the issue though. Here is a link to how I fixed. Not really a problem with lansweeper but I suspect some others may have this problem with xp in the future.
