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\CurrentControl Set\Servic es\LanmanW orkstation \Parameter s\ MaxCmds
HKLM\System\CurrentControl Set\Servic es\LanmanS erver\Para meters\Max MpxCt.
HKLM\System\CurrentControl Set\Servic es\LanmanS erver\Para meters\Max WorkItems
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

odd- according to the article here http://technet.microsoft.com/en-us/library/dd296694(WS.10).aspx, this should work absolutely fine.
