    Hi,

    in a program I call
       CryptAcquireContext(&hdl, NULL, MS_ENHANCED_PROV, PROV_RSA_FULL, 0)
    which always succeeds on some machines (esp. WinXP), but fails on
    others (Win2003 Server, but also other WinXP) with
    NTE_PROVIDER_DLL_FAIL (0x8009001D).
    I tried to remote debug the software on those machines but when using
    the remote debugger the call succeeds :-o.

    I tried to track the problem with FileMon from SysInternals, which
    shows me that in both cases the rsaenh.dll is looked up and found in
    c:\windows\system32. At some time the access pattern changes but this
    doesn't make sense to me (I can provide more details if necessary).

    Any hint what's going wrong here?

    Thx & Regards, Stephan
