Hello!
He are experiencing some issues with our site.
Here you have the server configuration: Server IIS 6.0 Windows Server 2003, .NET 2.0
After some time working well, we start to receive error 500 with:
<?xml version="1.0" encoding="utf-8"?><soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"><soap:Body><soap:Fault><faultcode>soap:Server</faultcode><faultstring>Server was unable to process request. ---> Object reference not set to an instance of an object.</faultstring><detail /></soap:Fault></soap:Body></soap:Envelope>At this moment we start to search more deep, and we found that all the Parameters to our WS are NULLS, that why the error!
How to solve it? well we call our main service from a Web Explorer www.abc.com/WebService/Services.asmx
and the system return to work properly...
