I have a Windows form app. It switches identity by calling LogonUser, then calls WindowsIdentity.Impersonate. While I'm impersonating, I'd like to copy a file from my machine to another machine in the domain via system.IO.File.Copy. The impersonation works just fine, however, the copy fails with "access to the path <target path> is denied" exception.
If I attempt to copy the file to a different directory on the same machine it works. If I log on to my machine as the impersonated user, and copy the file to a different machine via Windows Explorer, it works. Originally I was calling LogonUser with LOGON32_LOGON_NETWORK (3). Someone suggested switching to LOGON32_LOGON_INTERACTIVE. When I tried that, the Impersonate() failed with an exception "Unable to impersonate user". I'm running on Win2K. The original account has been granted the "Act as part of the operating system" user right. The impersonated account has been granted the "Log on locally" right on the source machine (ie. copy from) and the "Access this computer from the network" on the target machine (ie. copy to). Is there a way I can copy a file from one machine to another while impersonating?
