Make sure you have the latest patch for ID installed.
We are up to date. The problem happens in multiple versions of InDesign.
We've tested both CS5 (with CS5 indd files), and CS5.5 (with CS5.5 files).
I've seen that some people weren't getting IDLK files when opening CS5 files in CS5.5 because it was a temp file that needed to be saved up to the next version before generating an IDLK file, but that's not the same problem we are having.
Since it's started since you moved to a new server, I would suggest that there is a problem with the permissions on the new server. Is everything the same from the old setup to the new?
Well I'm waiting to hear back from my IT dept. I'm not 100% sure about changes to the new server. But I guess I'm somewhat fact-finding here so when IT gets back to me I can point them in the right direction.
Was hoping someone might have been thru this situation and might know what permission adjustments would affect the IDLK functionality.
And the correct answer is: SMB file protocol instead of AFP.
For whatever reason our new server and InDesign don't play well together where the .IDLK files are concerned. We tested multiple versions of InDesign so it was across the board.
After much trial and error we discovered that logging into the server via SMB set InDesign straight.
The .IDLK files now lock other users out of open .INDD files the way its supposed to work.
Thanks to Peter and Larry for their help also.
This thread is very helpful
May I ask about your file server setup?
We have two NAS file servers
