HKEY_LOCAL_MACHINE\SYSTEM\
you likely need to add it in those suggested parameter e.g. RequestTimeoutSecs, SocketIoTimeoutSecs and TcpMaxDataRetransmissions in accordance to your environment but can start off as mentioned in MSDN kb
http://support.microsoft.com/kb/811087
and do monitor the web log to see if there are specific error or blocking attempts, see below for more info

Step 2: Increase the Web Proxy Timeout Settings
To increase the amount of time that the Web Proxy service waits before it closes idle sessions, follow these steps: Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click the following article number to view the article in the Microsoft Knowledge Base:

so that under parameter, i do need to -> right click -> new -> string vlaue -> for adding the 3 parameter below ? as under W3Proxy, i do have performance , is it normal ?
RequestTimeoutSecs, SocketIoTimeoutSecs and TcpMaxDataRetransmissions
RequestTimeoutSecs, SocketIoTimeoutSecs and TcpMaxDataRetransmissions
Note the suggestion only applies if you use a proxy server. IN your case, ISA is the proxy to internet.
For RequestTimeoutSecs and SocketIoTimeoutSecs, if you see the link it is of type "REG_DWORD" not string. For its content (upon double click on it), you can choose the "Decimal'. Note that these fields are in HKEY_LOCAL_MACHINE\SYSTEM\ CurrentCon trolSet\Se rvices\W3P roxy\Param eters @ http://support.microsoft.com/kb/811087
For TcpMaxDataRetransmissions if you see the link it is of type "REG_DWORD" not string. For its content (upon double click on it), you can choose the "Decimal'. Note that this field is in the HKEY_LOCAL_MACHINE\SYSTEM\ CurrentCon trolSet\Se rvices\Tcp ip\Paramet ers @ http://support.microsoft.com/kb/191143/EN-US
I reckon the "performance" as more of performance counter though and may not be applicable
