Hi,

Please check the acls of the file and folders as I think these error are related to the Unresolvable SID from the file system folder at the level in which Inheritance begins.

Also check any errors or warning messages in the server logs.

from the windows domain, active directory side.

we try to delete some of them and the error has gone.

nas cifs server receive without problem de restore (good news)

these are the error from de backup server:

7/15/2010 4:09:17 PM E3452 Unable to write stream name. (FILE=\\SRVTEST01\test01\Users\Informatica\AGENCYS\Agencias\DATOS, ID=3, EC=The security ID structure is invalid.)
7/15/2010 4:09:17 PM E3452 Unable to write stream name. (FILE=\\SRVTEST01\test01\Users\Informatica\AGENCYS\Agencias\FORMS, ID=3, EC=The security ID structure is invalid.)

HI,

I am not sure of the windows tools but I found few tools that could be usefull but they are probably not freeware's "RemoveUnknown" was one of them.

I guess the windows admin would suggest you better way to do that. else you have to remove it manually  one by one...

SecurityExplorer from ScriptLogic - not freeware

I think EMC professional services also has some tools
