    Hello,

    On windows Vista, a GUI process calls OpenProcess on a NT service process. The NT service has already called AllocateAndInitializeSid + SetEntriesInAcl + SetSecurityInfo to enable all access rights for the process for everyone; this operation is done with success.
    On Windows 2k / xp / 2k3, the call succeeds.
    However, on Vista the call fails with ERROR_ACCESS_DENIED. Can someone help me about this? Is it a common issue for Windows Vista?

    Thank you.

    Vista is relatively new stuff and I can’t advise much about it. However I would try to set a debug privilege for the GUI process instead of editing ACL.
