Hi Satish,
If you have access, review whether the attachments have got a name and time stored using transction OAAD on archivelink.
Take a look at notes 1513057 and 1451769 (specifically for archivelink missing functionality). There are a bunch of notes around the missing time and creator name settings, please review them for your version.
I reviewed the settings on my system and I effectively don't get the same issue, we have linked the content repository to the archive server too.
Hopefully somebody on the forum can pitch in if the above notes don't help you.
Thanks,
Shrini
