Forefront TMG 2010 DNS request timed out problem
Hello everyone!
I have installed Forefront TMG 2010 on virtual machine (vmware vsphere)
OS - Windows server 2008 R2
Forefront TMG with all updates and rollups.
On this machine I have DNS request timed out problem.
When I run nslookup on TMG and enter request to external (non local) domain (for example google.com) I have DNS request timed out error.
I have got it only on first request , if I repeat my request I can have result and nslookup show my google.com ip address.
I have got TMG with 2 network interface installation .
First interfase for internal network It have ip address, network mask and local domain (DC) dns servers.
Secondary interfase for External network It have ip address, network mask, gateway, and doesn't have dns addresses.
Also I have routes to my local networks. It works correctly.
In my local network I have this DNS configuration:
Local DNS on Domain controller -> DNS Server with Internet access to externalnetwork and can resolve external DNS requests.
Other servers and local PC in domain can resolve external DNS requests without timed out problem, only TMG server have this problem.
