That would be on the client side. From the log of the XML you post to the server:
<meter-status>?</meter-status>[\r][\n]" Perhaps "?" is not a valid value for <meter-status>, which is what the error message seems to indicate.

[mailto:[EMAIL PROTECTED] On Behalf Of Eddie Lascu Sent: Monday, July 14, 2008 5:01 PM To: ADVANCED-DOTNET@DISCUSS.DEVELOP.COM Subject: Re: [ADVANCED-DOTNET] Web Service generates "Unable to connect to the remote server" exception Hi John, I am not sure I understand what you are saying. Basically, at this time, I am working on two fronts in parallel. One is to try to use the soapUI and get a response back. That will prove that the web service is running and there is no error returned by it when I invoke one of its web methods. The second front I trying to make progress is to do the same thing from my Visual Studio project. In both cases I am using a wireless connection to the Internet that bypasses the proxy server, so this should not be an issue. With soapUI I am somehow more advanced in that I have introduced the user name and the password for the request. The response that I get back seems to be generated by the server. If you are curios, here is the output of the HTTP log window in soapUI: Mon Jul 14 17:52:52 EDT 2008:DEBUG:>> "POST / HTTP/1.1[\r][\n]" Mon Jul 14 17:52:52 EDT 2008:DEBUG:>> "Content-Type: text/xml;charset=UTF-8[\r][\n]" Mon Jul 14 17:52:52 EDT 2008:DEBUG:>> "SOAPAction: ""[\r][\n]" Mon Jul 14 17:52:52 EDT 2008:DEBUG:>> "User-Agent: Jakarta Commons-HttpClient/3.0.1[\r][\n]" Mon Jul 14 17:52:52 EDT 2008:DEBUG:>> "Host: dap3.dot.ca.gov:18080[\r][\n]" Mon Jul 14 17:52:52 EDT 2008:DEBUG:>> "Content-Length: 934[\r][\n]" Mon Jul 14 17:52:52 EDT 2008:DEBUG:>> "[\r][\n]" Mon Jul 14 17:52:52 EDT 2008:DEBUG:>> "<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"; xmlns:atie="http://www.ATIE-00-00-01";>[\r][\n]" Mon Jul 14 17:52:52 EDT 2008:DEBUG:>> " <soapenv:Header/>[\r][\n]" Mon Jul 14 17:52:52 EDT 2008:DEBUG:>> " <soapenv:Body>[\r][\n]" Mon Jul 14 17:52:52 EDT 2008:DEBUG:>> " <atie:rMSResponseData>[\r][\n]" Mon Jul 14 17:52:52 EDT 2008:DEBUG:>> " <rmsMessage>[\r][\n]" Mon Jul 14 17:52:52 EDT 2008:DEBUG:>> " <rmsStatus>[\r][\n]" Mon Jul 14 17:52:52 EDT 2008:DEBUG:>> " <device-id>?</device-id>[\r][\n]" Mon Jul 14 17:52:52 EDT 2008:DEBUG:>> " <meter-status>?</meter-status>[\r][\n]" Mon Jul 14 17:52:52 EDT 2008:DEBUG:>> " <last-update>?</last-update>[\r][\n]" Mon Jul 14 17:52:52 EDT 2008:DEBUG:>> " </rmsStatus>[\r][\n]" Mon Jul 14 17:52:52 EDT 2008:DEBUG:>> " <assocLDSid>?</assocLDSid>[\r][\n]" Mon Jul 14 17:52:52 EDT 2008:DEBUG:>> " <organization-owning>[\r][\n]" Mon Jul 14 17:52:52 EDT 2008:DEBUG:>> " <organization-id>?</organization-id>[\r][\n]" Mon Jul 14 17:52:52 EDT 2008:DEBUG:>> " <organization-name>?</organization-name>[\r][\n]" Mon Jul 14 17:52:52 EDT 2008:DEBUG:>> " </organization-owning>[\r][\n]" Mon Jul 14 17:52:52 EDT 2008:DEBUG:>> " <rms-location>[\r][\n]" Mon Jul 14 17:52:52 EDT 2008:DEBUG:>> " <latitude>?</latitude>[\r][\n]" Mon Jul 14 17:52:52 EDT 2008:DEBUG:>> " <longitude>?</longitude>[\r][\n]" Mon Jul 14 17:52:52 EDT 2008:DEBUG:>> " </rms-location>[\r][\n]" Mon Jul 14 17:52:52 EDT 2008:DEBUG:>> " <station-status>?</station-status>[\r][\n]" Mon Jul 14 17:52:52 EDT 2008:DEBUG:>> " <meter-rate>?</meter-rate>[\r][\n]" Mon Jul 14 17:52:52 EDT 2008:DEBUG:>> " </rmsMessage>[\r][\n]" Mon Jul 14 17:52:52 EDT 2008:DEBUG:>> " </atie:rMSResponseData>[\r][\n]" Mon Jul 14 17:52:52 EDT 2008:DEBUG:>> " </soapenv:Body>[\r][\n]" Mon Jul 14 17:52:52 EDT 2008:DEBUG:>> "</soapenv:Envelope>" Mon Jul 14 17:52:52 EDT 2008:DEBUG:<< "HTTP/1.1 500 Internal Server Error[\r][\n]" Mon Jul 14 17:52:52 EDT 2008:DEBUG:<< "Server: gSOAP/2.7[\r][\n]" Mon Jul 14 17:52:52 EDT 2008:DEBUG:<< "Content-Type: text/xml; charset=utf-8[\r][\n]" Mon Jul 14 17:52:52 EDT 2008:DEBUG:<< "Content-Length: 762[\r][\n]" Mon Jul 14 17:52:52 EDT 2008:DEBUG:<< "Connection: close[\r][\n]" Mon Jul 14 17:52:52 EDT 2008:DEBUG:<< "<?xml version="1.0" encoding="UTF-8"?>[\n]" Mon Jul 14 17:52:52 EDT 2008:DEBUG:<< "<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"; xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xmlns:xsd="http://www.w3.org/2001/XMLSchema"; xmlns:tmdd="http://www.TMDD-Partial-02-00-01"; xmlns:ATMS="http://center-services/atieSoapHttpServiceBinding"; xmlns:ATIE="http://www.ATIE-00-00-01"; xmlns:ClientDummy="http://center-services/clientSoapHttpServiceBinding";><SOA P-ENV:Header></SOAP-ENV:Header><SOAP-ENV:Body><SOAP-ENV:Fault><faultcode>SOA P-ENV:Client</faultcode><faultstring>Validation constraint violation: data type mismatch in element <meter-status></faultstring></SOAP-ENV:Fault></SOAP-ENV:Body></SOAP-EN V:Envelope>" The server generates an internal error and closes the connection.
