Troubleshooting - checking the CSP (ISA server)

The three main issues that may occur with the Client Site Proxy for ISA server are:

• The CSP ISA plug-in does not have any custom logs within ISA.

  The best way to check that the CSP works correctly is with two policy rules in the portal.

  See Troubleshooting - testing the Client Site Proxy with web Security policy rules.

• To see the standard ISA server logs:

  1. Start the ISA server administration console.

  2. In the left pane, select Monitoring.

  3. In the right pane, select Start Query or Edit Query as necessary.

  You can now see queries to the ISA firewall.

• ISA server cannot contact upstream proxy

  The cause may be network issues or firewall rules on the local ISA server or (if the ISA server is not the edge device) on the edge firewall.

  Try the following:
  Refresh page: Search for the page again by clicking the Refresh button. 
  The timeout may have occurred due to Internet congestion.
  Check spelling: Check that you typed the web page address correctly. 
  The address may have been mistyped.
  Contact website: You may want to contact the website administrator to 
  make sure the web page still exists. You can do this by using the e-mail 
  address or phone number listed on the website home page.
  If you are still not able to view the requested page, try contacting 
  your administrator or Helpdesk.
