limited number of running services

[Greg]

hey guys

I'm running some Windows 2000 Adv. Servers and I was
installing several services which have to run
as "Administrator" (or an other local user, but not as
SYSTEM!). The services are all of the same type..

After I try to run the services, I'm only allowed to start
some of them (number is depending from server to server:
on one I can start 18 of these Services, on one 22 and on
the third 26).
I was also trying that on my Windows 2000 Workstation. But
there was no problem with running 40 Services and more
installed to run with a windows user..

R there any restrictions on that in Windows 2k AS?

Thx 4 ur help!!!

I read about this in Kevin Miller's Professional NT Services from Wrox
publishing on page 264 (Chapter 7).

It seems that every service logon with a userid requires a desktop and every
desktop requires a USER Heap which requires
a contiguous linear address space. The thing is that there is an upper limit
on liner user heap space of about 48MB and
since each USER heap typically consumes 3MB of memory you can get only 16
winstations created.

It is telling this to convince people to use localsystem for services since
it is handled differently.

There is a registry entry that can be modified to change the size, it is
also mentioned in this KB article that I found
