No - basically I did not understand the issues involved in accessing a network on another machine and could not find how to enter any required password to enable this access, until shown the way. Neither ZA nor the router firewall were in the way. The original (working) network connection was made from the client which had the same account password and account name as on the host - ie mine. The 'forbidden' access was from a different username on the client and needed to be 'masked' by 'connecting with a different name'. Instructions covered the use of a Mapped drive. If anyone knows a 'fiddle' to persuade the host that it can 'accept' the different user without setting up a mapped drive that would be useful. E&OE in that explanation
