Hello, 

I've got 5 Windows 2003 Terminal Servers setup with Windows Network Load 
Balancing and part of a Session Directory. This means that the 5 TSs each have 
an individual IP but also share a common IP. The TS Farm is presented on the 
common IP so when you attempt to connect the the common IP one of the TSs picks 
up your request in a round robin fashion. Once your login creds are validated, 
the TS also check the Session Directory to see if your login currently has a 
session on another TS. If it does, then that TS redirects you to the TS you 
were on and your session picks up where you left off. This is a really cool 
feature and works perfectly within the local network. 

My problem is that the TSs are in a datacenter so the users will be connecting 
remotely. My first choice for this connection is to use OpenVPN and have each 
user access the terminal servers through the actual TS common IP via the VPN. 
My second choice is a DNAT with a public IP at the firewall. My problem is that 
neither of these work when redirected to an existing session. If the user 
doesn't have a session then they can use the TS they originally connected to 
just fine. But if the Session Directory attempts to redirect - the RDP client 
just fails. 

Additional possible issues: The NICs are Broadcom GbE Teamed for failover. The 
network load balance cluster is set in Multicast mode. If I set them in Unicast 
mode I can't ping in or out on the common or dedicated IPs. 

Any help, advice, pointers to how-to's is greatly appreciated. 

Thanks
