I have inherited a SharePoint 2010 environment from my predecessor who never documented anything, and used their production environment as the test environment as well.
Anyway, all sharepoint 2010 servers are VM's that connect to a physical backend SQL server. All front end servers have very low CPU and memory usage. The main site all users connect to uses SSL, and is accessible from the outside.
1) How can I be certain that when users access the site internally, they are going through the internal network instead of going through the external network? When I ping the server FQDN name internally, it replies on a different IP address as compared to when I ping it from an external connection.
2) When I use network monitor 3.4 to view traffic, I see that 99.99% of the traffic is all TLS based (Please note, this site is using claims authentication with kerbose) In the packet trace though, I see tons of frames that contain the following TCP:[Continuation of # 108] the number keeps changes though, but I think you get the point. Does this mean packets are getting retransmitted? I also see that a number of packet contain the following "Negotiating Scale..."
Thank you in advance for your help
1. This is typically set on your DHCP server. When a machine connects to your network and retrieves an IP from DHCP, they typically get an internal DNS server address as well. If they are inside your network, they are using your internal DNS server.
Out of curiosity.....have you tried creating a new test web application and site collection, to see what performance is like there? That will narrow your scope of problem (possibly).
