This looks like a startup/initialization problem rather than a permanent hardware fault: the machines show the network icon but apps and mail fail until a user logoff/logon. That pattern (happens every morning, affects everyone, McAfee present) narrows the likely causes to DHCP/DNS/authentication not being ready at the time users start work, a network/security agent interfering at logon, or a NIC driver/power-management quirk.

Start by diagnosing while the problem is present on one machine (do not disable corporate AV without approval). Run these commands in an elevated Command Prompt and record results:

ipconfig /all
ping 127.0.0.1
ping <default-gateway-from-ipconfig>
ping 8.8.8.8
nslookup www.google.com
ipconfig /renew

Interpretation guide: if the gateway ping fails, the issue is link/port/switch or NIC power state. If gateway replies but 8.8.8.8 fails, the upstream/router/DHCP path is suspect. If 8.8.8.8 works but DNS lookups fail, focus on DNS settings. If ipconfig /renew restores connectivity, DHCP timing/lease or server reachability at startup is the prime suspect (this ties to 's server timeout idea).

Next checks and mitigations: inspect Event Viewer (System log) for DHCP Client, Network Location Awareness (NlaSvc) and Netlogon errors. Verify NIC driver version and disable the adapter power-saving option ("Allow the computer to turn off this device to save power"). If machines are domain-joined, enable the Group Policy "Always wait for the network at computer startup and logon" to force synchronous network initialization. Temporarily test whether McAfee components block traffic (have security staff run the test or check McAfee agent logs) — enterprise AV/host checks can delay or block network stacks until policy loads.

If a quick fix is acceptable, add a logon/startup script that runs ipconfig /renew or schedule a task that runs at boot. Longer term, involve network ops to check DHCP server availability and switch port behavior (802.1X/port security) and coordinate with security to confirm McAfee policies aren’t interfering.
