Red X on Network drives and Unknown Publisher when running apps after VLAN config

We have been running the SG500-52P switches (2 switches stacked) for 2 years with No issues. We recently moved our office and added a new VoIP phone system. We had some trouble getting everything installed originally but its all working now with this one pesky problem. After putting the switches in Layer 3 mode, adding a VLAN for the phone system and setting up a route between VLAN1 (data) and VLAN2 (phones). We are now having this problem: Users are randomly getting Red X's showing disconnected network drives. There appears to be no pattern to when the disconnect happens. It can happen almost instantly after a reboot or sometimes be fine for a few days before disconnecting.  If you click on the drives you can access the data but the Red X DOES NOT go away. Although when accessing some applications we get an "Unknown Publisher" message and usually the program crashes. All our Workstations are Win 7 Pro and Servers are 2008 R2. We map server and NAS drives, when the issue happens is disconnects all the mapped drives and NOT just one server.

Definitely not a good

Definitely not a good situation to be in, as you never know who will call and complain of loosing connectivity.  Have you opened a ticket with TAC?

Unfortunately we don't get a lot of comments/questions on the SG series here.
