concurent UNC connection limit

I have a standard 2008 r2 server that i am using as a file server, and BizTalk 2009 running on a enterprise 2008 r2 server.  BizTalk has a couple thousand UNC recieve locations looking at the file server.  i can only have 512 of those recieve locations turned on at a time.  If i try and turn on more, they will eventaly fail with an error like: "The FILE receive location \\StgFS01v7\xx*.* exhausted the network retry attempts. ".  back in Windows server 2003 you can get past this max concurent UNC limit by modifying these registry keys:
HKLM\System\CurrentControlSet\Services\LanmanWorkstation\Parameters\ MaxCmds
HKLM\System\CurrentControlSet\Services\LanmanServer\Parameters\MaxMpxCt.
HKLM\System\CurrentControlSet\Services\LanmanServer\Parameters\MaxWorkItems

These keys do not exist in windows 2008 r2, but i added them anyways to test (to both servers of course).  I still have the limit.  I tryed to use SMB 1.0 instead of version 2.0 that comes with server 2008 R2, followed this guide:
http://blog.korteksolutions.com/disable-smb-20-on-windows-server-2008/

still nothing.  This is not a problem with BizTalk, if the recieve locations are looking at the local hard drive, there is no problem.  only when the recieve locations are looking at a UNC path.  

Any help would be great, thanks,
Steven

I was forced to abandon my FileServer, add a hard drive to my BizTalk Servers' VM and have the recieve locations look localy.  This is no longer a high priority for me.  but still, If anyone has some idea on how to fix this UNC problem, i would really like to go back to using a centralized file server for my Biztalk Processing.

thanks,
Steven
