DHCP & DNS Issues

[glenimp617]

Need to pick some technical brains please:

I have my IT dept arguing with each other at the minute, so I'd like a second opinion.

The first line guys say that when laptops are moving between buildings in our company, the IP address is changing (buildings are on different subnets), but when they try and remote control using the machines name, it's trying to connect to the old IP address.

Looking in DNS, it's got the old IP of where the machine was a day ago.

The third line team are saying this is normal behaviour, but the first line team are getting annoying at not being able to use machine names, and having to spend a few extra mins each time in tracking down the new IP.

I know DNS scavenging, it's switched on.

any ideas?

In a normal MS envir this is normal. We have the same issues with people travelling to different buildings and the subnet changing, so this causes issues with the fortigates allowing internet. Normally after 5 minutes of being on the new subnet it sorts it self out.

Scavenging is set as low as it can go.

Yeah we also have a fortinet firewall

I'm sure the guys were saying it was an issue for days
