Do you really need the /3GB switch on a DC?  Also, you may have a driver that won't function while in /3GB mode.

“Failed to create a desktop due to desktop heap exhaustion.” is logged when the heap itself cannot be created. If a desktop heap cannot be created, then the entire desktop creation attempt fails. Usually a failure to create a new desktop heap means that session view space is exhausted for the session. You may be able to resolve this issue by increasing the size of session view space (using the SessionViewSize registry value) or by decreasing the third shared section value (assuming session view space is primarily used by non-interactive desktop heaps), to allow for more heaps to be created. Before making any changes, I suggest you use dheapmon to view desktop heap usage on your system shortly after you see the error. It helps to understand the usage of desktop heap before making changes. FYI, the desktop heap failure errors are only logged once per session to avoid a flood of events in the event log. So you may actually have more than one failure per session, but only one is logged. Desktop heap logging can be enabled or disabled with the DesktopHeapLogging registry value (see MS KB 810807).
