Cocaine

Hi All, This is my first post in the BI Forums. I've been trying to resolve this issue myself for sometime, but I'm all out of tricks. I have posted this in the OGN forums, but I've have no responses. This is definately a Vista issue, hence I posted in this thread rather than the 1.11 thread. ArmA 1.08 works perfectly in Vista and ArmA 1.11 works in XP. I have noticed some strange differences in the network traffic between 1.08 and 1.11 in Vista. Which I believe prevents the Server List from downloading. Which is my issue; I can't get a Server List to download in 1.09 or 1.11 in Vista. I took some screen prints on Netstat to show which TCP connections are made during the Sever List download. First the application sends a SYN to 207.38.11.35:80 and then when it gets an ACK. It sends a SYN to 207.38.11.14:28910 and receives an ACK. Both these address' are from IGN. This happens exactly the same way whether I run ArmA 1.08 in Vista or ArmA 1.11 in XP, but doesn't work with ArmA 1.11 in Vista. In Vista when 1.11 sends the first SYN to 207.38.11.35:80 the application hangs (waiting for a ACK). Then when the SYN timeout expires it attempts to send a SYN to 207.38.11.14:28910. Which also times out and the application fails to get a Server List. I took a TCP Dump using WireShark of what occurs when ArmA connects to IGN to get the Server List. The first thing the application does (ArmA 1.08 in Vista) is make a DNS query for 'armedass.available.gamespy.com'. This is the same in ArmA 1.11 running in XP, but not in Vista. When running in Vista, ArmA 1.11 skips the DNS query for 'armedass.available.gamespy.com'. I assume that this is the critical difference which is stopping it from working. My question is; Does anyone know why ArmA 1.11 in Vista is not doing the DNS query? and/or What do I need to check/change to get ArmA 1.11 working in Vista? I have followed all of the troubleshooting tips for the Operating System, and due to the fact that 1.08 works (and 1.11 in XP). I can rule out my router configuration. My Hardware Config is; AMD Athlon X2 5600+ 2x 2Gb Patriot PC-6400 (limited to 3Gb) EVGA 8800 GTS 320 Asus M2N-SLI Deluxe Vista x64 SP1 Any Suggestions? Thanks, Coke
