There is a domain on the internet corp.com (not owned by us) which has an entry in its dns-records with a wildcard (*.corp.com)
Our AD domain is corp.com
The problem only occurs when using a VPN connection. Connecting to a resource on a domain other than corp.com fails. It first searches the primary DNS suffix, but does not find the resource here. Instead of searching in the DNS suffix search list (where it can be found), it searches a public DNS server and finds *.corp.com…
The DNS-suffixes are connection-specific suffixes for the VPN connection.
Why does the public DNS-server has priority over the DNS suffix search list defined in the connection?
Can anyone point me in the right direction to solve this problem?
