I have a 501 with a VPN set up. Once the VPN is established, I rdp to an internal server. Usually, I have no problem; I can connect repeatedly from either my desktop or laptop computers.
The problem is that after another user connects RDP and disconnects, RDP is no longer available for any users. What I usually do is go in and reload the configuration. The vpn still works but RDP cannot go across it. My config is as follows:

I don't see how the vpn works at all. Your acl 101 for nat exemption and split tunnel is not correct. It should be...
access-list 101 permit ip 10.1.1.0 255.255.255.0 10.1.2.0 255.255.255.0
add additional inside networks as required...

This seems to be working - Let's hope it stays that way...
