"Could not contact server" error

We are evaluating Sophos ESDP and will purchase it if it works as needed. Our network is a win2k8 domain. On all of the systems that I've deployed the Endpoint security and control client from Enterprise Console they are getting the 'Could not contact server' error message when it tries updating so the client is disabled. I've deployed it to XP, wink3, win2k8, win2k8 r2, vista, and win7 and none worked. One of the win2k8 r2 server didn't work then about a day later it started updating and working on it's own. Nothing was changed on that system from the time it wasn't working until it did work.  I saw a knowledgebase article about adding the local SophosSAU*0 user to the local 'User's group. I did that and it still doesn't work. That is not an acceptable answer in the first place since the whole point of a centrally managed system is that we should NEVER have to touch the client/workstation. It should all be done centrally from  Enterprise Console, group  policy and/or System Center. If I ever have to touch the workstations to make this work and maintain except on the rarest of occasions then your product is a no go. I've also turned off the firewalls to test and it's still not working. Speaking of firewalls, what ports does the system use to communicate that need to be opened.

Thanks,

Patrick

  • I had the same in my environment, but only with machines that were not part of my domain.  It turned out that my web filter was blocking access to the update download site.  Once I made the exception in my filter, things worked just fine.

    One more thing you may want to do is check your Hosts file and make sure there are not any entries that may be blocking access. 

    Hope this helps.
