I will pay for this fix 20 bitcoins thus making it worth your while.
My error is...
Traceback (most recent call last):
File "guiminer.py", line 826, in toggle_mining

WindowsError: [Error 6] The handle is invalid
GUIMiner version: v2011-07-01
Operating system: Windows 2008 R2 Server Core Hyper-V
Miner backend: OpenCL/poclbm
Video card: ATI 6850
Server: deepbit and solo mining NameCoin
I know you may not support server core but the HyperV OS is free and mining poclbm from the command line works fine.
Here is a link to download a configured HyperV for mining...
http://forum.bitcoin.org/index.php?topic=9679.0The HyperV.vhd download does not have the latest GUI Miner installed but it's located in C:\Software\Miners\poclbm folder.
Thanks and Good luck
BTW
I have already tried copying the Windows\sysWOW64 folder full Windows 2008 R2 Server computer but that did not work.
