EP Server totally failed. Need to reinstall. Old clients reconnecting?

Aminocom

Hi,

The server running our Sophos EP failed last week. We've now rebuilt the server and everything is running once more....except the EP services.

I've got no problem installing and reconfiguring everything, however I've got 100 or so orphaned clients around the company that somehow need to be reconnected to the server without the need to push out the software again.

Is there an easy way to do this?

We do have tape backup's from this particular server, so would it be easier if we could retrieve something from the tapes. A database maybe?

Thanks for any pointers.

    Hello Aminocom,

    did you already install SEC? And - are these 100 clients all your clients or just a part (then what makes them special)?

    As of right now I've done nothing to reinstall SEC.

    The server has the same identity as the old one (Host Name and IP) of course it will have a different UID, but that shouldn't matter.

    I didn't want to reinstall anything only to find that first I should have retrieved something from our backup's.

    If I just reinstall SEC, as long as the server host name is the same, as clients attempt to "call home" they will automatically start populating the SEC database?

    Hello Aminocom,

    the same identity as the old one (Host Name and IP)

    there's just one more important piece of identity - the certificates used by RMS. Without the original certificates the clients will "refuse" to talk to the server. If you can retrieve these keys and import them before installing the clients should connect to the management server as before. Of course all other settings have to be reentered. 

    Dunno how your tape backups were taken and can't say what you will be able to restore (and how easy) or not. Please have a look at How to back up and restore your Sophos Management Server for what normally should be backed up.Fell free to ask if you have further questions.

    HI,

    If the new server install is already in place but with new certificates so the existing clients are unable to talk, you could use the HTA tool here:

    http://www.sophos.com/en-us/support/knowledgebase/116737.aspx

    To generate a VBScript to run on the "now unmanageable" clients that will re-initialise them so they can talk to the new install.

    Suggest creating the VBS and test it on a couple of clients before mass deployment.

    Regards,

    Jak
