The code for this hasn't changed but this all started in late August and I still haven't found out why. At first I thought it was because the pages were using http://tempuri.org so changed those to http://microsoft.com/webservices but that had no effect. Is there a way to debug this? It's on a live server and I'm having to manually invoke the web methods which work fine this way yet not when called from the windows service. I've checked for firewall issues, permissionsand other things that could be blocking and haven't found anything. All clues appreciated ... tom mallard analyst/architect, SDE Reply timallard Member 260 Points 156 Posts Re: Webservice giving HTTP status 400: Bad Request error Sep

Diagnosing HTTP ErrorsTroubleshooting HTTP 400 Errors in IIS Troubleshooting HTTP 400 Errors in IIS By Mike LaingNovember 27, 2012Tools Used in this Troubleshooter: Network Monitor HTTP Error logging This material is provided for informational purposes only. Microsoft makes no warranties, express or implied. Overview After sending an HTTP request to an IIS server, an HTTP client (such as Internet Explorer) may display the following type of error message: The webpage cannot be found. HTTP 400 Most likely causes: There might be a typing error in the address. If you clicked on a link, it may be out of date. What you can try: Retype the address. Go back to the previous page. Go to Bing and look for the information you want. If the HTTP client is Internet Explorer, and the Show Friendly HTTP Error Messages option is turned off, the error may resemble the following: Bad Request In these scenarios, IIS has rejected the client's HTTP request because the request did not meet the server's HTTP parsing rules, or it exceeded time limits, or failed some other rule that IIS or HTTP.sys require incoming requests to adhere to. IIS sends the HTTP 400 - Bad Request status back to the client, and then terminates the TCP connection. Troubleshooting Methods When troubleshooting an HTTP 400 condition, it is important to remember that the underlying problem is that the client has sent a request to IIS that breaks one or more rules that HTTP.sys is enforcing. With that in mind, you will want to see exactly what the client is sending to IIS; to do this, capture a network trace of the client sending the bad request. You can analyze the trace to see the raw data that the client sends to IIS, and to see the raw response data that IIS sends back to the client. You can also use an HTTP sniffer tool called Fiddler; this is a great tool as it allows you to see the HTTP headers even if the client and server are communicating over SSL. The next data item you will want to use is the C:\Windows\System32\LogFiles\HTTPERR\httperr.log file. Beginning in IIS 6.0, the HTTP.sys component handles incoming HTTP requests before they are passed along to IIS, and is the component responsible
