Xenpp App Server Load Balancing availability/Status going offline intermitently!!

We are running XenApp 6.0 Farm (All Vmware VM's) on Windows Server 2008r2 sp1 with XA600W2K8R2X64R01 HRP.
One of the Servers called "S2"in the farm keep dropping off the Load balancing table.

G:\>QFARM

Server Transport Network Address
-------------------- --------- --------------------
S1 TCP/IP 172.30.8.62
S2* TCP/IP 172.30.6.122
S3 TCP/IP 172.30.8.64
S4 TCP/IP 172.30.6.193

G:\>lbdiag Word 2007

Server Name Server Load Server Address
------------------- ----------- --------------------
S1 3670 172.30.8.157
S3 6005 172.30.6.193
S2 OFFLINE

On QFARM /Load the server does not appear at all. "enablelb" command fixes the issue temporarily but I'm under pressure to find a permanent fix.

Any Help will be greatly appreciated...

Thanks a mill! based on the advice on the post virastar referred me to I noticed right away that the Ctxsta.config UID was different from the Servers MAC . I will change monitor the server and report back. I am not sure if changing the CHM&R tests to just alert and not disable LB is a good idea but I consider it as a last resort.

The issue happened again until I removed the server from the farm and re-added it after the STA fix. It been work fine for at lease a week now with no issues :)
