I'm having major problems with my ip configuration settings. I want to be able to use a fixed ip address and gateway for my wireless network connection. The problem is that after I've changed the configuration of the IP version 4 connection properties to the fixed ip I want to use and ok it. My system crashes with a Stop error (Bsod) implicating the file tcpipreg.sys as the culprit.Ive tried disabling Ip version 6 as I thought that maybe they were clashing somehow, but other than that it seems Im stuck using DHCP which is annoying as the reason I am trying to switch off DHCP is to solve another problem. Namely that Every time I start up my computer my connection shows Limited or no connectivity and I am forced to either Diagnose and Repair my connection or ipconfig /renew in order to get an outside connection.The adapter is a Realtek RTL8187 and is an integrated device on my Asus P5N32-SLI Premium Motherboard.My specs areAsus P5n-32 SLI PremiumIntel Core 2 Duo E6700 2.66 Ghz (Stock Speed)2Gb Corsair TWINX2048-6400C4 800MhzOnboard Soundmax HD SoundXFX Geforce 7950GX2 520M 1GbDDR3Vista Ultimate 64bitThis is what Windbg came up with when I ran the Memory.dmp through itMicrosoft (R) Windows Debugger Version 6.8.0004.0 AMD64Copyright (c) Microsoft Corporation.

Hi, Thanks I realize that debugging is beyond the scope of this forum but does anyone have any simplesuggestions as to what I can try to get round thisbefore I have to shell out 46.00 just to speak to someone at microsoft. Do you know of any way I can change my ip config without using the "networkconnection properties"?What would I need tomanually edit in the registry to achive the same outcome?Is anyone aware of tcpipreg.sys causing any problems in the past? What does tcpipreg.sys do? can I get a newer version? etc. Thanks, sorry to pester but 46 is a lot of money for a phone call (I'm way beyond my 90days from activation)

Hi, You may configure the IP address by using netsh command. Example: netsh interface ipv4 set address name="Local Area connection" static 10.0.0.9 255.0.0.0 10.0.0.1 1 For more information, please refer to the following article: Netsh commands for Interface IP http://technet2.microsoft.com/windowsserver/en/library/61427fbd-de1f-4c8a-b613-321f7a3cca6a1033.mspx?mfr=true Hope the information is helpful.
