I have code that calls RegConnectRegistry to make a remote registry connection. This code works just fine for all OSs except Windows Vista. I noted that the new SDK indicates a call to LogonUser and ImersonateLoggedOnUser should be called before calling RegConnectRegistry. I implemented these two new APIs before calling RegConnectRegistry. Both APIs indicate success. However, I still cannot make a remote connection to Vista's registry. I tried turning off the Vista Firewall to no effect. I can see the Vista computer from the other computers on my home network. The error message back from RegConnectRegistry is 53 (The network path is not found). Has anyone any experience with this? Is it simply a configuration or policy setting in Vista that needs modification? JW
