Adobe PDF networking error

I have several users on a 2012 RDS server that access a PDF from a Server 2012 windows file server. This PDF has many fillable fields like Name: with an empty text box next to it.

Sometimes when the users open this PDF everything is missing except the fillable text fields. If they try to save the file they get the following error:

the document could not be saved. an unexpected network error occurred

Obviously, this sounds like a networking error, but 2 things.

1) The terminal server and the file server on both VMs on the same ESXi host, using the same SAN. Seems unlikely to be a networking error. No other networking errors on any server.

2) This doesn’t happen to every user, it seems to be only affecting 3 of about 40 right now, and it doesn’t happen all the time.

Any thoughts? I have checked to see if there were any hidden lock files, but that wasn’t it. Google-fu turned up nothing. When a user accesses a file from a file share, where do the lock files get created? I see no lock files in the shared folder, are they in the user profile somewhere?

Only other avenue I’ve considered: Is this a problem with how Server 2012 handles simultaneous users accessing the same file? The file is pushed out with GPP.

Aside from just nuking the affected users profiles I’m not sure what else to try. Adobe is up-to-date.

Thanks for your help
