WYSE V10L Terminals losing connection daily

We are having an odd problem that no one can seem to figure out.  We have 40ish wyse terminals that will daily at just after 6pm lose their vmware session they are actively working in.  This is not a timeout...  and it does not seem power related because the terminals don't actually reboot.... they just flash back to the VDMclient login screen.
Logs have been submitted to VMware, they see the disconnects but cannot find any cause for the disconnects.  I am wondering if somehow it could be terminal related??  Any help is appreciated.

Dont have experience on WYSE whatsoever, but just a stab in the dark ...

Could the broker server that manages the WYSE terminals be the cause. It could be doing a backup or something and this could be the reason they all log out...

Thanks Sage.  I was wondering about that, but my understanding of the broker server is that it only establishes the initial connection..... after that time the broker could actually go down and the existing connections would still stay active.
-- We have ruled out power as an issue because we have put some of the terminals on UPS and the issue still occurs.
-- Our network guy says it is not network related, but I am still thinking it might be some type of network router/switch issue possibly thowing dhcp proxy requests out or something along those lines.  We just aren't finding anything yet though....

Anyone else ever seen this issue??  Help!!
We have the same problem with all our V10L boxes.  They fail to get DHCP requests half the time.  It's a nightmare and it's not a network issue.  I have tried multiple DHCP boxes, Windows and DHCP turbo, and on different networks.  All the same issue.  I have yet to figure it out.  All our normal pc's work fine.  If i find anything out i'll let ya know.
After doing some network captures i have found that the Netgear switches we have use STP and not RSTP.   The spanning tree protocol normally blocks all traffic on any port that becomes active for about 30 seconds.  If we disable it, all the wyse boxes work instantly.  IT seems as thought the wyse DHCP gives up before XP does trying to get an address and it falls in that 30 second time frame some times.  Try disabling spanning tree if your switch uses it.  Our HP's all use RSTP so they don't exihibit the problem.
