Web Application - Page cannot be displayed (intermittent issue)

[Ewan]

Hi

i have created an application for use for 15 people. Where they can update their comments/actions taken on a particular order or request.

The app is a VB Asp.net WebApplication created in Visual Studio 2008.

i am using IIS on Windows XP Professional to host the application.

My problem is, the users face intermittent issues with "Web Page cannot be displayed". (The system im hosting this app from is on 24hrs)

Could anyone let me know what could be causing this and is there any fix? Thanks

What exactly is the error code (404 means the page cannot be found, 500 means that there was some error that happened on the server so the page couldn't be displayed....)

Check the Windows Event logs for any indication of errors that could be happening.

Hi Frinny

i get the following message:

There are too many people accessing the Web site at this time.

* Open the Server home page, and then look for links
to the information you want.




Some times i get the following error:

XP has limitations to the number simultaneous connections (I believe it's 10 connections).

Apparently you can increase this limitation up to 40 connections by modifying the IIS metabase.

This is the command that I found online that will do so (you need to use command line to execute this):

cscript adsutil.vbs set w3svc/MaxConnections 40  

Please note that you must be in the \inetpub\adminscripts directory before executing the command.
