One of my users noticed something peculiar when working on text or document from a DFS share.
The user will save changes and leave the doc open. Preliminary tests show that around 10min+ is when user receives an error, "THE SYSTEM CANNOT FIND THE PATH SPECIFIED". The user hits the "OK" button and is presented with a "SAVE AS" dialog in the same working directory. User hits "SAVE", dialog warns of an "overwrite" and hits "OK" again and text or doc gets saved.
I was able to reproduce the problem myself. I opened an online stopwatch and set a count down of 12 minutes. Every 3 minutes I added some text and hit save. All was well until the last 3:45. I added some more text, hit save and BOOM - error occurred, "The System cannot find the path specified".
The two servers that hold the DFS share are Windows 2012 R2 boxes. One sits in the LA site and the other in Chicago. According to the output from "get-dfsrbacklog", there is no backlog between the DFS servers - all appears sync'd. Also, logs appear clean except a few of errors in the event log and DFS replication health report regarding sharing violations.
Anyone seen something like this? Any suggestions on how to troubleshoot?
