I've got Visual Studio 2008 running on Windows 7 64bit UltimateRC, when I try to build a project hosted on a unc share I get the following error:An error occurred loading a configuration file: Failed to start monitoring changes to 'filepath' because the network BIOS command limit has been reached. For more information on this error, please refer to Microsoft knowledge base article 810886. Hosting on a UNC share is not supported for the Windows XP Platform.In both XP and Vista this was resolved by adding/increasing the MaxCmnds and MaxMpxCt entries under HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\LanmanServer\Parameters but this isn't working with Win 7.Any suggestions or workarounds for this other than storing the files on the local machine?

same problem here

Did you every get this to work?

Add a REG_DWORD registry entry FCNMode and set its value to 2 to HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\ASP.NET. The following table lists possible values for the FCNMode DWORD value and the behavior that is associated with each value. Value Behavior Does not exist This is the default behavior. For each subdirectory, the application will create an object that will monitor the subdirectory. 0 or greater than 2 This is the default behavior. For each subdirectory, the application will create an object that will monitor the subdirectory. 1 The application will disable File Change Notifications (FCNs). 2 The application will create one object to monitor the main directory. The application will use this object to monitor each subdirectory.

I am using Visual Studio 2010 running on Windows 7 64bit Professional and had the same issue. As mentioned in the post above, setting the FCNMode to 2 under HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\ASP.NET fixed it. Thanks!

Running Visual Studio 2008 on Windows 7 64bit Enterprise. Similar issue. Adding the FCNMode value 2 worked for me. There are lots of other web posts that point to http://support.microsoft.com/kb/810886. That did not work for me. Thank you.

How nice that someone shared this knowledge, running Seven Ultimate 64 bit on Mac, there was no way i was going to find out for myself! Problem solved Thank you!

Perfect. Thanks for sharing. Additionally I can confirm that this solution also work on a Windows 7 Ultimate 32-bit. Only difference is, you should add the FCNMode key to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\ASP.NET.

I had a parallels VM to a file share to my host Mac hard drive and changing this registry setting fixed it. I had to log out and log back in though.
