Hi,
There are a couple of aspects to the Windows 7 security model which try to prevent elevated remote access (i.e. agent pushes),
- UAC blocking elevated administrator tokens on file shares
- Administration shares being disabled by default
The symptom of (1) above is that when you authenticate as an administrators group member to file share the access token you get is diminshed (the administrators group portion is removed from it). To resolve, turning off the UAC certainly works. There might be specific policies you can enable/disable though in the UAC myriad but I've not been able to determine the key policy here.
The symptom of (2) is that although you can access other shares on the target computer, you can't get access to the administrative ones, getting the error "Network Path Not Found" in this case. To resolve this open Regedit. Navigate to HKLM\Software\Microsoft\Windows\CurrentVersion\Policies\System and create a new DWORD: LocalAccountTokenFilterPolicy with the Value of 1.
In short, you'll not be able push the agent on Windows 7 without first ensuring you tackle the above so you can be granted elevated access the windows folder remotely.
Hope this helps,
Ian./
