Photoshop 10.0.4 on Windows 7. Have enabled remote connections and set a password of 8 char.
On Adobe Nav I find the connection and it asks me for the password. After entering the password it waits a few seconds and then reports "Server not responding".
I can access the PC from the iPad using RDP so the connection should be OK.
Further to my previous answer I think that the problem lies in the network configuration.
I have a wireless ADSL router and the iPad is connected to this through WiFi. My PC is connected to a a network port on the router but between the PC and the Router there is a Netgear XAVB101-100UKS Powerline AV Ethernet Adapter which acts as a bridge.
When I changed the configuration and connected the PC over WiFi then Nav connects as it should.
Unfortunately this is a problem as I need the speed of the Powerline Adapter for RDP connections to another PC and the distance is too great for a quality WiFi connection.
Anyway the mystery is solved. Many thanks for your help.
