Hi,
we've been trying to solve an intermittent "Permission denied" access problem on a NTFS qtree for some time now, to no avail, so maybe some of you will have some advice.
We have a CIFS- and NFS-exported NTFS qtree on a FAS3020 cluster running Data ONTAP 7.1.1. The PDC is a win2k3 server, and Unix users are managed via NIS.
From time to time, legitimate users are refused access to certain files with a "Permission denied" message, especially when trying to access the qtree via NFS. These users *do* have permission to access the files in question as per NTFS ACLs -- in fact, when they retry to access the file a few minutes later, they are granted access.
We're seing this problem since a bit more of a week now, and still have no clue what the cause of the problem could be... the SID cache seems to be a good suspect, but it's hard to tell; we've also thought of buggy win2k3 patches...
In parallel, we're seing the following messages in the logs: CIFSRPC SamrGetAliasMembership: Exception rpc_s_unknown_reject caught.
Has anybody experienced a similar problem ?
Simon
