We manage an Exchange 2000 Standard Server. We encountered the problem described in "XADM: Err Msg: Invalid Windows Handle ID No: 80040102 Q313333" when trying to alter public folder permissions on a certain public folder sub-structure.
I obtained "pfinfo.exe" off the SBS4.5 RSK, and its version of "pfadmin.exe" as well. I also found an "updated" version of "pfadmin.exe" on the Exchange2k RSK.
Exporting the permission to a .txt file using "pfinfo.exe" is easy enough, but importing those permissions reliably back into the Exchange2k public folder structure proved to be more difficult. I have, in the meantime, resolved the issue with a bit of a manual work-around that took about an hour or so to implement.
I was wondering if you perhaps have had any experience with this, or if you knew of a nice article/guide that would help expedite the process (using the Exchange2k "pfamin.exe," for example).
Have a look at KB article Q270905, which discusses this issue. It also includes instructions for resolving the error you received.
