Just wanted to share some things we have been experiencing to see if anyone else is seeing this. First on SEP 14 MP2, we had a lot of our SQL servers get to a point where they would respond to pings, but we would be unable to RDP. I found some articles that mention this is resolved in RU1 so we have upgraded these SQL servers and so far none has experienced this issue again, however we have another issue that may be separate where a file server's SMB shares will randomly stop working. You can still RDP to the server, and even hit shares going out from the server. In an attempt to gather logs, I ran SymDiag and enabled debug logging and this runs the smc -stop/start command. Once this was done and logs were being gathered, we noticed/tested and SMB shares were working again. This is the 2nd time this specific server has done this since upgrading to 14 RU1. We have a 2nd suspect server that may be experiencing the issue but we are in the middle of verifying if disabling SEP has any effect. Not all servers are up to RU1, but this is making me a little scared to fully move to RU1.
I do have an open case and will try and remember to report back if any progress is made.
