Custom designed POS app in MSAccess and VBA that uses ODBC to query/display customer data from SAGE. Need to write changes back thru ACCPAC views. The POS front-ends run as standalone networked PCs. SAGE 300 runs on a VM in the backoffice. Coding is stuck at writing back as I cannot successfully execute the accpac.RemoteConnect command to 'cross over' to the VM. Error: "Underlying connection was closed: Either there was a fatal error on the server or client authentication failed." 

Any help or a different approach would be appreciated.
