Your computers’ status is checked basing on the response of ICMP ECHO Request. If uplook server does not receive an answer from a given computer, it will check the resource as unavailable.
Solution:
- Make sure that the firewall does not block ICMP Echo Request packets -> the computers respond to PING requests.
- In Tools->Options->Computers->Online tester tab set the paramteres according to how your network is configured (e.g. ICMP only)
- Turn off Dynamic IP address update. It will result in the server checking out the computers basing on IP addresses sent by the agent instead of checking DNS server.
If despite the changes the status of your computers is still displayed incorrectly – contact us via e-mail: [email protected]
