    Post AB Tutor Control: Problem with finding clients

    We have a new computer ICT room of about 10 PC's, which currently have AB client installed and running on each machine. All machines are currently NOT on the domain.

    At first, I couldnt see any machines through AB Control, so i added an exception into Windows Firewall to include ABclient.exe. and after a reboot on all machines, they quite happily appeared in AB control.

    However, I have just started to notice that I can only see 2 or 3 machines at any given time, and the odd thing is, the machines vary between which ones are viewable in AB control E.G. PC 01, 02, 03 may appear and then a few hours later PC 07,08,09 migt appear.

    Has this got anything to do with the machines not being on the domain (DNS/DHCP issue?) or it there something I am totally missing here

    From what I recall, AB uses DNS and DHCP to resolve the machines names. Do you use static IP's?

    No we don't. IP's are supplied from the DHCP server. Its just strange that they 'sometimes' appear.

    Sounds familiar... I think we had something similar and it turned out that DHCP and DNS where not in synch - Have you contacted AB for advice?

    Yes I have, they supplied me with a troubleshooting manual which hasn't been to any use so far. I will keep looking into this and post if I find a solution

    Problem was solved my creating a new group and manually adding in the computer names into that group. Although they still look offline, when attempting to connect, they all seem fine.
