Trend Micro DSM agentless VM clients status keeps changing

I'm using TrendMicro DSM 9.0 as the antivirus solution for our VDI pilot.  We just upgraded the VMware infrastructure from ESX 5.0 to 5.1 U1, along w/ View, vShield Manager, vCenter.

For almost every VM I've upgraded the VMware tools on, I see their status in the DSM Manager as "Anti-Malware Engine Offline" sometimes, and other times most of them switch back to "Online".  For the VM's that have not been upgraded yet, they stay consistently as "Online".  

I've verified the View Agent has been upgraded properly.  I've verified the vShield system driver is running on the VM's.  I'm not sure where to go from here.

Let me know what other details I can provide!

I've also had a similar issue with only one of the vm's in our cluster using Trend Micro DSM agent less. All other guests are fine.

I tried uninstalling and re installing the vm tools which worked for a limited time, though the issue is back.

Try re-installing vm tools and make sure you choose complete installation.

If the issue returns or persists then I'd also try this which has permanently resolved my issue:

Do the following:

1. From the vCenter, Power-off the Deep Security Virtual Appliance (DSVA).

5. Deploy DSVA.
Note: Do not activate the DSVA yet after installation. You need to configure it first.

6.Change the Network Adapter settings to be in the same network as the DSM.
