ok this is what i get after every reboot:The TCP parameters differ between IPv4 and IPv6.TCP Parameters for IPv4 Connections----------------------------------------------Receive-Side Scaling State : enabledChimney Offload State : automaticNetDMA State : disabledDirect Cache Acess (DCA) : disabledReceive Window Auto-Tuning Level : normalAdd-On Congestion Control Provider : noneECN Capability : disabledRFC 1323 Timestamps : disabled** The above autotuninglevel setting is the result of Group Policy overridingany local configuration.TCP Parameters for IPv6 Connections----------------------------------------------Receive-Side Scaling State : enabledChimney Offload State : enabledNetDMA State : disabledDirect Cache Acess (DCA) : disabledReceive Window Auto-Tuning Level : normalAdd-On Congestion Control Provider : ctcpECN Capability : disabledRFC 1323 Timestamps : disabled** The above autotuninglevel setting is the result of Group Policy overridingany local configuration.any clue on how to get my settings sticky?i know it has to do with my current modem but im not planning to change it so soon so i was wondering if there is any registry entry that prevents it from resenting after reboot?!?Thanks in advance,RR

Hi, Please try the following to modify the settings again and see how it works: Information about the TCP Chimney Offload, Receive Side Scaling, and Network Direct Memory Access features in Windows Server 2008 If the issue persists, please also collect the Group Policy Result from the problematic Windows 7 client: a) On your DC, run the Group Policy Result wizard to collect the data of RSOP in GPMC. b) Right click Group Policy Results---> Group Policy Results Wizard… c) Choose Another computer and point to the Windows 7 client. d) Select that problematic user account and click next to collect the group policy result data.
