Manager takes down internet

[TTSadmin]

Have you ever had an issue with IP Office where when you access the manager application it shuts down internet access for the entire office ?

This happens if we access it on the customer’s PC and when we use Logmein.

Network administrator blames the IP Office.. Tech blames the customer network.

It is an IP Office R8 with the UCM module for voice mail (recently replaced because of the issues with a defective lot)

Manager > Preferences > Disable all shown features and try again.

On windows servers it can detect the BootP server of Manager and assume its another DHCP server and shutdown it's own. Never seen it take down the internet, they need to investigate how if its true, but I don't see how it can

if the internet is being accessed via a proxy on the windoze server it may kill it i suppose
there is also a registry mod for the windows small businesses server to prevent it shutting down its dhcp server which is an insane design choice in the first place

Network troubleshooting:

What is the exact nature of the "loss of internet"?
What is the IP Scheme? Feel free to be generic, I'm looking for NAT vs Firewall.
What is doing the routing between the local computers and the internet? Windows or Linux server, or network hardware such as Cisco or Netgear?
Can you ping the gateway?
Can you ping local subnet computers?
If there is more than one subnet that must be routed between, can we still ping between subnets?
What about traceroute? On Windows: "tracert -d 8.8.8.8"
What actions are necessary to bring the network and/or internet back online? Simply close Manager? Reboot/powercycle switches?

If @amriddle01 is correct and a Windows Server is shutting itself down due to multiple BootP servers, split the network into Voice and Data subnets on separate VLANs/Broadcast Domains.
