Hi I have setup a site 2 site vpn setup using the access server and Layer 3
Site A where the access server is uses 192.168.1.0/24
Site B where the client is uses 192.168.16.0/24
I can ping clients on site A from site B, and I can also ping clinets from site B to site A.
From site B I can access all resources on site A using the ip address of the client machines.
For example I can access the remote desktop on site A 192.168.1.199 from site B, My problem is I cannot access remote desktop on site B 192.168.16.199 from site A, but I can ping 192.168.16.199 from site A no problem.
Firewalls are all tunrned of.
Any ideas what I need to change to get this working please.

First the obligatory "don't use the 192.168.1.0/24 subnet" because it will easily conflict with existing subnets in existing router setups.
Then, since you can ping all the way across from a machine in the network on site A, to a machine in the network on site B, and vice versa, it seems very unlikely that the issue has anything at all to do with OpenVPN. More than likely, it is still a firewall or a software setting in remote desktop.
You say firewalls are turned off, but I very often see people claiming to have switched something 'off' but it just toggles a setting in a program that allows everything through - but the program itself is still present and is still a part of the flow of traffic, and if it is misbehaving, it can still stop traffic. Unintended, I'm sure, but still. So I'm skeptical. But....
At this point the only thing that you can do that takes a constructive approach that will get you some clear results is to run packet capturing programs like WireShark and TCPdump to monitor exactly what is happening to the packets you're sending, and where exactly they are able to pass through correctly, and where exactly these packets are either turned away or ignored/filtered. I don't think you need to look at OpenVPN at this point yet, until you have conclusive evidence that OpenVPN is the problem here. I'd run packet captures and see what happens to the traffic.
