If you have encountered an issue accessing photos, sketches or documents via RealWare and you are running Symantec (Anti-Virus) on the CAMA server, there is a known issue with Windows Server 2008 and Symantec.  

Basically, the Windows XP clients lose connectivity to Windows Server 2008 64-bit file shares and DFS shares after a period of time when the server is under load during production hours. The Windows Server 2008 itself does appear to be working and does not show any signs of a deadlock. 

This problem is fixed in Symantec Endpoint Protection 11.0.4202.75 (MR4 MP2) or later, and the Windows 2008 operating system should be running Service Pack 2 or higher.
