Hello friends, I'm trying to troubleshoot the remoteapp intermitent connection drop. we have a 3 RDS Servers and one connection Broker and a Hardware loadbalancer. Uers get disconnected randomly and it's completely random. So i have decided to monitor the connections on one of the RDS servers and i see quite a few colour coded as Black. Can someone have a look at this let me know what is happening here?

That's just because the IP checksum in the packet is different than the one generated by Wireshark, probably due to IP checksum offloading into the NIC driver.
Regarding your question:
There are two TCP Reset in the capture file and both are sent from the client to the server.
In the capture file itself there is no indication why the connection was closed. The client could have received all requested data or it could have received data it did not expect (see logs) and thus closed the connection with a RESET.
So, what are the symptoms of the 'connection drop'? Any messages in the logs? You need the time stamps of those events and then see if there are any 'unusual' events in the capture file at the same time stamp, given, that the time of the involved systems and the capture machine are in sync.
You say, there is a load balancer involved. I guess you have 'sticky connections' (connection persistence) enabled. Maybe the problem is caused by a timeout of some sticky connections. In that case, you would need a capture file near the client and right after the load balancer.
