We have about ~110 Cisco Anyconnect clients and management vpn configured + anyconnect cisco umbrella.
Works fine for 99% of them.
For some we see the randomly following happening: (especially on newer machines)
- user tunnel connected.
- user disconnects tunnel manually
- in 1-2 minutes mgt tunnel is started automatically
After that for some clients DNS is broken. ping works to all segments. but no DNS.
To solve this: either reboot or run things like:ipconfig /releaseipconfig /renewarp -d *nbtstat -Rnbtstat -RRipconfig /flushdnsipconfig /registerdns
