The page cannot be displayed

Hi All,

My user is receiving 'The page cannot be displayed' error while accessing the netweaver portal. This is an intermittent problem and he is located at a remote site. Hence, I am suspecting that this error is due to slow network response causing the request to timeout.

Firstly, how can I retrieve the logs (from portal, AS ABAP, web dispatcher, etc) which will list the request and response time for this user? This will help me to determine if our system did receive the request and if this error is cause by slow response from our system.

Secondly, how can I extend the duration for page request timeout?

Many Thanks
