NT privilege question

[Robert Ouzen]

Hi to all
 
I have a client Windows 2003 with a mapped network drive (S:) I tried to backup 
but got this error:
 
Incremental backup of volume 's:\ds01\*'
ANS1449E A required NT privilege is not held
 
I had I think for my login user (administrator) all the privilege I can think 
about (administrator group , backup ...)
 
What I missed ????
 
My client version of TSM is 5.3.0.14 on a TSM server 5.2.4.2
 
T.I.A Regards
