HP thin client t410 RDP Client Error Windows Server 2008 R2

I'm having an issue with 2 of my HP Smart Zero t410 thin clients. They each RDP into an XP SP3 virtual machine hosted on a virtual server running VWWare ESXi 5.0.0. Randomnly in the morning they'll both disconnect from their virtual machines. Sometimes at the same time, sometimes not.

I'm monitoring both the thin clients and the virtual machines with software that pings everything 30 seconds, nothing ever drops a ping. I've tested the wire, the wire is good. I've made sure the thin clients are up to date with the latest firmware. The last thing I've tried is replacing the switch both of these machines are connection.

One thin client comes up with an error message "RDP Client Error: Reboot Necessary" then below "The firmware has experienced a critical error. Please reboot this client." After I close the error I can RDP back in.

The other thin client also gives an "RDP Client Error" and down below mentions MANTICORE but I did not write down the entire error message.

I have 30 other t410's deployed at various locations, all connected via RDP to a Windows Server 2008 R2 terminal with no issue for over a year. These last two have maybe in for three weeks and have continously thrown this error randomnly.

Any help is appreciated.

Do you have the latest up to date network card drivers--check device manager for NIC and go to their website for the latest driver--don't rely on Windows Update for this.

The t410s are thin clients running a modified version of Linux. The virtual machines are XP SP3. To what network card drivers are you referring too?
Lionel MMSmall Business IT ConsultantCommented:
it has to be on the two "new" devices, the ones that are the only ones with this problem. And since you have made sure it is not the cables or the switches or the network cards themselves then the only thing that I can think to check is the drivers and if it is a linux system then check HP's site for the latest version for these systems.
