Question
Connection Problem
Hi everyone,
One of my clients have tight security and they cannot access FMS using IP address but only by DNS name.
I think this is some kind of proxy setting but anyhow that is the story.
So, using a DNS name solved my problem? - not quite!
If I use DNS name there is about 20 seconds of delay until it makes successful connection to FMS.
I was able to figure out reason of this by looking at the traffic.
Attempt by the client to connect to the IP address of FMS on 1935 (5+ secs wait then fail)
Then Attempt by the client to connect to the IP address of FMS on 443 (5+ secs wait then fail)
Then Attempt by the client to connect to the IP address of FMS on 80 (5+ secs wait then fail)
Then Attempt by the client to connect using the DNS name xxx.mydomain.com to FMS on 80 (Now it works!)
I understand that it tries on different ports until connection is successfully made causing delay but I cannot find any article saying it uses IP address before trying with domain name!
Is this default behaviour of NetConnection object?
Is there any way to overcome this and force using DNS name from the beginning?
Thank you in advance!
