We have a VLAN setup for visitors in our building. We have a DHCP server setup with the appropriate scope and it works great from 8am until 2pm. At 2pm on the dot the server will stop giving out IP addresses like clock work. Where in the DHCP are the setting to restrict log on time? We would like to restrict it to 6pm but cannot find the spot to do so. Thanks in advance.

I'm pretty sure there is no option in Microsoft DHCP to specify at what times during the day it will lease IPs.

Also, stopping DHCP leasing IP's after 6, won't stop people using the network.  A users lease will have to expire before they can no longer access the network.  Not to mention that they could just specify a static IP.

Are you sure you don't have the 2pm time limit specified on your router/firewall isolating your wireless VLAN?

We are not sure, unfortunately our switches and firewalls are handled by a network business solutions so I have informed them of the problem as well. Right now just using all available resources to see if it is on our (server) side.

This is the VLAN for our visitor wireless unsecured so we arent really worried too much about that side. We had it setup just so random person couldn't park his car outside the building at night and get free wireless.

I suspect the 2pm time is being enforced by the network infrastructure rather than the DHCP server.

Do all the wireless clients loose their connection to the network at 2pm?  Or is it just new ones trying to join the network?

Not the solution you were looking for? Getting a personalized solution is easy.

Just new ones trying to log on. If they already have their IP lease then they work just fine.
