DNS Timeout over AnyConnet VPN

[kroerig]

Hello,

I have a strange problem with AnyConnect. When I connect my Windows 10 notebook via AnyConnect to our ASA 5512 my client needs about 12 sec for DNS query. It seems that Windows first tries to use the IPv6 DNS servers, that it gets from my home router and as these requests time out (2 sec) Windows then falls back to my companies DNS server that Anyconnect configure.

Any ideas how to change this?

We don't use IPv6 within our internal network.

Thx,

Klaus

 - Perhaps  , then , you could disable ipv6 'globally' in windows 10 :

I think it try DNS in ASA then use SP DNS.
