I have remote access vpn setup and I can get connected with no issues. I assigned the vpn a pool of addresses from the end of my inside interface subnet. When connected I can ping any device on that subnet, I can also connect to my switch on the same subnet via my browser. I can not however access any device located in my dmz while connected. This is a new setup I'm testing but I need vpn user to be able to use rdp to connect to machines in the dmz. I have attached my config any advice would be greatly appreciated.
Result of the command: "show running-config"

some suggestions
1. Use a network address in a different subnet from inside network for vpn client IP pool. saying 192.168.10.0/24
2. enable nat 0 on dmz interface
access-list no_nat_dmz permit ip 10.10.10.0 255.255.255.0 192.168.10.0 255.255.255.0

Are you access DMZ network by using 10.10.10.x IP or Nat-ed IP 38.x.x.x?
Please try to use 10.10.10.x IP.
You can check the following to narrow down the issue.
1. make sure the host in DMZ allows the access from 192.168.10.x
2. check client statistics info to see if both encry/decry count is incrementing
3. you do a packet capture on dmz interface to see if you could see traffic in both direction.
access-list dmz permit ip 10.10.10.0 255.255.255.0 192.168.10.0 255.255.255.0
access-list dmz permit ip 192.168.10.0 255.255.255.0 10.10.10.0 255.255.255.0
capture cap access-list dmz interface DMZ
use "show capture cap" to see what packet is seen in DMZ interface.
4. check the log to see if there is any clue. - "show log"

Thanks for your help I was finally able to get it working after i cleared the Nat translation. Your No Nat for the DMZ network command seemed to do the trick..
