JSI Tip 8031. When you configure Windows 2000 services to start in a user account context, only approximately 16 services start?

Every service that is started in a user account context requires a desktop, which requires a USER heap, which requires a contiguous linear address space.

The default USER heap requires approximately 3MB of memory.

The maximum USER linear heap space is 48MB.

The number of services that can be started in a user account context is therefore 48MB/3MB, which is 16.

You can set the non-inactive desktop heap size to 512KB, allowing approximately 96 services to be configured to run in a user account context.

See tip 0052. Change SharedSection=1024,3072 to SharedSection=1024,3072,512.

NOTE: You must restart your computer for the change to become effective.
