Is your ICA protocol bound to the correct NIC? Check tscc.msc, ICA, Network Adapter Had some issues with that once after clooning a server Msg: #9 in digest From: <christopher.walter@xxxxxxx> Date: Tue, 28 Apr 2009 18:44:23 -0400 Subject: [THIN] Re: Cannot connect to 4.5 server externally If it was the firewall ports I believe you get a message about there being no server on the specified subnet. If it was the alternate IP address you get a message saying there was not alternate IP address found. Everytime I have seen protocol driver error it has been network or routing. If it is working via RDP then I would say your NAT is fine and you have a problem with the Alternate IP address. Did you perhaps set the alternate IP address on the wrong NIC?
