We have Mac users that copy files onto an NT Server. The NT Server is backed up 
by Tivoli. All older Mac files that were backed up by ADSM have now lost there 
MAC header (they are shown as PC files now). Mac doesn't recognize the files 
unless the user adds a file extension to the filename. Thousands of files have 
been corrupted. Has anyone seen a similar problem after upgrading? Does anyone 
know of a fix? I currently have a PMR open with Tivoli Support. I opened the 
ticket last week and the support guy told me that the files must have been 
touched by a PC somewhere along the way. This is not the case, the files were 
fine before the upgrade. All new files that are put on the MAC Volume of the NT 
server are fine when backed up by Tivoli. Something must have happened to the 
older files when we upgraded to Tivoli.

Here's our environment:
Mac user copies files to mounted Mac Volume on NT 4.0 Service Pack 6 server 
running Tivoli client 3.7.2.19. The NT server gets backed up by Tivoli 3.7.4.3 
running on AIX 4.3.2 server. The files go straight to 3494 tape library and are 
kept on tape for 26 months.

Any help will be greatly appreciated.

Thanks,
