I posted a thread regarding some windows boxes showing status 13's every 
day on backups.
Thanks for the replies...

to recap i run solaris master server netbackup 5.0MP2 and connect to 
mixture of unix and NT clients most of which are win2000 with client SW 
5.0mp2

What is so weird is some windows boxes work and some dont and the same 
ones dont each day. I have uninstalled and reinstalled client s/w. I 
have enabled logging and as someone suggested looking in online_util/log 
file on the client. This did show something erroring saying snapshot 
information and that Volume Manager wasnt installed. Something along the 
lines :-

vfms_mothod_error 3.
Flashsnap_init: veritas_volume_manager not installed.

Now i know its not installed because i dont use it., and dont use the 
snapshot part of nbu for these windows boxes. Whats weird is the other 
boxes have same directories within c:\program files\VERITAS\  of help 
and Netbackup  thats it.

I couldnt find any info like someone suggested re disks and not being 
scsi in the logs either. Its all just odd.
I have separated all windows clients into their own policies away from 
the unix ones too and set the Policy Type to Microsoft-NT still no joy

Anyone any more suggestions?

Thanks
