After installing the BizTalk Adapter on a SharePoint (SPA1) Server, I wanted to have access to the btsharepointadapterws.asmx webservice via internet explorer.
I receive a Server error, with no extra information.
Even if I played by changing the CustomErrors tag in the web.config, I didn’t receive any extra information.
Open the file
C:\Program Files\Microsoft BizTalk Server 2006\Business Activity Services\BTSharePointV3AdapterWS\web.config
Under System.Web -> WebServices - >Protocols you will see
Put this line as comment and save the file.
No you will have access to the webservice.
