Environment:

TSM Server: AIX with TSM V5.1.1.4
Client : W2K with TSM 5.1.1

Client is connected to an EMC NAS and used to backup the NAS

We obtain the message "FileOpen(): Unable to determine current compression state
of 'unc-name of file'. DeviceIoControl: Win32 RC=1" for every file that we want
to backup. Sometimes we see the message "GetDfsInfo(): EntryPath=unc-name of
file, Server(null), Share(null) NetDfsGetInfo() returns RC=1722

We use this client to be able to backup the datamover because the TDP apparently
does not yet support an EMC environment.

Did anyone experience the same problem?
