If a client gets to the point of lease expiation either they are already disconnected, actually could be many reasons or the DHCP is down and in the later you will have a many disconnects. DHCP renewal I believe begins at 50% of lease time. So yes, the client will lose all connectivity.

Microsoft webstie it says &quot;If no DHCP server is available by the time the lease expires, the client immediately unbinds itself from the existing lease and starts the process to obtain a new lease, beginning with a DHCPDiscover message.&quot;<br />
<br />
Does it mean the client would lose IP and stop networking ?

What happens if client can't communicate DHCP server when IP lease expired in T2 period ?

The Dynamic Host Configuration Protocol (DHCP) is an auto configuration protocol used on IP networks and an extension of the Bootstrap Protocol. DHCP allows for computers to be configured automatically to communicate with each other over an IP network without the need for manual setup by a network administrator. The implementation of DHCP relies on a DHCP server to hand out network configuration information to DHCP-capable clients that request an IP address (and other information required or useful in communicating with other devices on an IP network). In addition to an IP address, common configuration information served over DHCP includes a default gateway, subnet mask and DNS sever(s).

The Windows operating systems have distinct methodologies for designing and implementing networks, and have specific systems to accomplish various networking processes, such as Exchange for email, Sharepoint for shared files and programs, and IIS for delivery of web pages. Microsoft also produces server technologies for networked database use, security and virtualization.
