Your First Job You Will Start With Immediately

Fault-finding network engineer
Our network suffered the catastrophic loss of a Windows domain controller, along with the backups of that domain controller.

Since building a replacement Windows domain controller, the network has been unreliable at times. We believe this may be due to some errant or missing Group Policy on the new controller, or due to some client settings that are still pointing at the missing server. Due to the loss of the old domain controller, we are unable to cross-check settings.

At times, some Windows clients appear to lose connection, at least for some types of traffic. This causes issues for the VOIP software that they are using. This may be a firewall issue, although the Windows firewall is disabled on these machines.

There are also some Linux servers on the network. Their role in this disruption is not fully understood, as they were configured by a member of staff who has since left the company.

We require an experienced all-round network troubleshooter who has in-depth knowledge of Windows and Linux who is able to:

* read Wireshark traces and determine the root causes of disruption
* configure Windows domain controller and DHCP server
* configure Windows clients
* configure Linux servers
