Thanks, David

I am not sure about concurrent connections limit but if you use this property, you can customize 503 message using IIS7 custom errors. Thanks, Kj

  Re: Custom error messages for Service Unavailable (503) Error Messages Reply Contact That might work... I am trying to do this with WSS 3.0, but I am not aware if there would be any unexpected effects from this approach.  I wonder if anyone has tried it before.  Does a custom error for 503 work when applied just at the application level?  I could not get it to work when I applied it to the web site (it behaved the same as it did in IIS 6.0, from what I saw). Regards, David

When you say it doesn't work, do you mean custom error configuration at server level is effective and not at the site level? How is system.webServer/httpErrors section looks like at site/application level? Thanks, Kj
