The vault from a partner company is replicated onto our local pdm server, files are replicated on-demand.
For most files this works great, but now I'm coming across files that I cannot pull across, and I get the attached error. It "seems" to be files created on the other end of the line. If I create files on this end, they have no problem seeing them over there.
The files in question (because it's what I'm currently working on) are Word Documents. Could it be a mismatch between 2003 and 2010 versions of Word? I wouldn't think so, at least I should still be able to GET the file, but I can't.
Has anyone experienced this? 
Here's a follow up for those interested. The inability to get certain files and not others was continuing.
I logged onto the archive server and I couldn't access the vault, or the admin tool. And THEN I REMEMBERED GETTING THIS EMAIL LAST WEEK.....
Hi Corey. We have to change your HOSTS files on your computers. To be able to reach each others servers, we had to change the IP’s a little. Everything is working now and I tested it last night when I finished.
In the HOSTS file where it has the address 1xx.xxx.xxx.x, we need to change it to 1xx.xx.x.xx
I went through and updated all the client host files, but forgot to do so on the Archive Server. So I updated the archive server, and Viola!!!
