Web service issues

I have a web service written in asp.net (that was working just fine until today) deployed on a remote server.

The webservice is vehicleinfo.asmx

The weird thing is I run the web service code from vs on my local box and all runs well.

I have a configuration setting for database and have it pointed to the production sql server and all is fine

If I tried to execut the web service on the remot machine I get to the screen with the list of methods but when I try to invoke one.  It returns the ever helpful HTTP 500 Internal Server Error



Just to make sure I copied the  files

global.asax

vehicleinfo.asmx

web config

along with the bin files

back to the remote server from my local machine

still same thing

I got a utility called wcfstorm and put in the url to the web service
It returned a

-<getVINInfo>
-<MethodParameters>
-<FaultException>

 I looked up  80070005 and it seems to point to a permission error but everything looks fine

Any ideas????
