Hi, 1. In windows server 2K3, I cant find the TcpTimedWaitDelay registry key (http://technet.microsoft.com/en-us/library/cc757512(WS.10).aspx). Does its absence mean that default value is used or is it a symptom to anything else ? How to set the default value ? Can I just set the key, or do I have some Win. component missing and need to be installed? Shall the server be restarted ? 2. I noticed that one of the services on my machine fails to restart because when it statrs after shut down it fails to open TCP port (seem that it is in use), do you think it might be related ? Thanks in advance, Z.

Hi Z, Thank you for your post. 1.Windows Server 2003 does not add this entry to the registry. You can add it by using the registry editor Regedit.exe. In your post article, it express clearly that TcpTimedWaitDelay key missing to add and its value should be default value 120. If you want to add the key, just set up TcpTimedWaitDelay=dword:30 under HKLM\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters . 2.Change TcpTimedWaitDelay setting is in order to release a closed connection and reuse its resources. It used in IIS/SQL hundreds of connections waiting listening scenario. You could run command netstat -ano | find "portname" to find if the service still used that port. If yes, end service process to release the port. Otherwise, please provide more information about your service restart failed issue. If there are more inquiries on this issue, please feel free to let us know.Regards, Rick Tan
