I have a ISA 2006 server I need to troubleshoot. Clients on the inside cannot do DNS lookup nor can they reach external websites.
- No enterprise policies is applied before array firewall policy
- One deny all policy is applied after array firewall policy
- A long list of policies is aplied as 'Firewall policy rules'
Which plocies needs to be in place to allow a client to perform a DNS lookup on an external DNS?
I've tried to monitor all traffic to the specific DNS. When doing a DNS lookup from the ISA itself I get a fine log entry.
When doing the lookup from a client I get no log entries. Any ideas?
