We have a new server setup for our Umbraco sites which is 5 x VMWare ESXi virtual Windows 2008 R2/IIS 7.5 servers running across 2 large physical servers. All data is stored on a single Dell PowerVault MD3200i SAN and currently the IIS servers access the SAN via UNC which is served by FreeNAS.
I have setup a test site on one of the servers, with the AppPool running under the context of a windows user I created for the purpose as running using ApplicationPoolIdentity resulted in permissions errors. This appears to work initially however after a short time I get the following errors in Event Viewer:
Failed to start monitoring changes to '\\fileserver\WebShare\Umbraco_Test' 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.
I have tried making the registry changes referenced in the Microsoft KB article however this does not resolve the issue.
I have also tried setting FCNMode=2 and whilst this stopped the error above, it also prevented the client-facing site from reflecting any changes made to MasterPages/XSLT in the admin section until the AppPool was recycled.
If anyone has experienced any similar problems I would be grateful for some help with this issue as it is extremely frustrating at the moment.

Having the exact same issue... Haven't found a fix though :-(
Hi
I fixed this by using af symbolic link, som umbraco think it uses a local path.
The link can be made form a command promt, and should be done on alle webservers, by running the command:
mklink /D c:\IISData \\iis\iisdata\ (Please edit path as needed)
Regards Lars.
@Lars
But it's still on a share, so eventually you'll hit the network BIOS command limit right?
You are absolutly correct!
I didn't read the question properly, because I thought this was another thread, sorry!
