When you refresh schemas in the SLX connector schemas you may get the following exception:
System.Web.Services.Protocols.SoapException: System.Data.OleDb.OleDbException: Unable to initialize data dictionary. Invalid object name 'SYSTEMINFO'
The error “Unable to initialize data dictionary. Invalid object name ‘SYSTEMINFO'” is returned by the SalesLogix OLEDB provider when it is denied access to the following location:
C:\Documents and Settings\Default User
Give account that the SLX Connector web service application pool runs under READ access to the Default User folder.
