That's probably related to the maximum size of the system heap.  Have a
look into the "Remarks" section in the MSDN man page of CreateDesktop: 

http://msdn.microsoft.com/en-us/library/ms682124%28VS.85%29.aspx

It explains the registry setting which can be changed to raise the
system heap size.  For services the third value of the SharedSection
option is relevant.
