If your MET/TEAM website is functional and Customer Portal is giving you an Error 500 you can reference your MET/TEAM setup in IIS for configuring Customer Portal.

First, you want to use the following causes of Error 500 article to troubleshoot found here: Common Causes of Error 500 in MET/TEAM

Compare the settings mentioned in this article between MET/TEAM and Customer Portal and if there are differences, you should be changing Customer Portal to match MET/TEAM.

Next you want to ensure the Serial Number value from MET/TEAM web.config file matches exactly the Customer Portal web.config file, updating Customer Portal if there is a mismatch.

  • On the computer hosting the MET/TEAM website, use a text editor such as Notepad to open the MET/TEAM web,config file, typically located here:
      C:\inetpub\wwwroot\METTEAM\web.config
     
  • Locate the line near the top that begins with:
     <add key="SerialNumber" value="
     
  • Copy the entire line
  • On the computer hosting the Customer Portal website, use a text editor such as Notepad to open the MET/TEAM web,config file, typically located here:
      C:\inetpub\wwwroot\CustomerPortal\web.config
  • Locate the same row that begins with:
     <add key="SerialNumber" value="
     
  • Paste the copied row from MET/TEAM above the existing row in the Customer Portal file
  • Compare the "SerialNumber" GUID values and if they are different, delete the row originally in the Customer Portal file, leaving the one copied from the MET/TEAM web.config file and then save the Customer Portal file.
  • If the two serial numbers matched, close the Customer Portal file and don't save the changes, this was not the issue, move to the next topic.
  • If the SerialNumber GUID values were different and you saved the Customer Portal Web.config file, use IIS Manager to restart the Customer Portal website and also recycle the CustomerPortal application pool.
  • Re-test Customer Portal and see if the error is resolved.

 

Check is IIS Manager since many Error 500 messages are the result of bad Connection Strings.

  • Open IIS Manager on your computer

  • Test Customer Portal again and see if it now works.
