Your DHCP server’s scope is too small for the number of computers that are connecting to it each day. The majority of your users are wireless and come and go during the day. Due to change control restrictions, you can’t increase the size of your DHCP scope to add more addresses until the weekend. What else could you do to provide a temporary solution to this issue?
Why would you want to go with a DHCP solution that has a high availability for your company? Â Which is better? Â Any drawbacks? Â Why is this the option that you would rather go with? Â How soon do you anticipate the DHCP server on your network failing? Â How soon will the DHCP in your house stop working?

However, the remote office is three hours’ drive away, and you’re pretty sure this will be a simple fix if you can just see it. What kind of video service can you use, with the help of an employee at the remote office, to see the switch from your desk?
