% Registry Quota In Use Performance Monitor counter = 100% - server 2003 SP2 Enterprise 32 bit
Bruce Sanderson
Server 2003 Enterprise SP2 32 bit) that we'd appreciate any help that you
folks may be able to provide.
Users get a message at logon that their roaming profile can not be loaded.
We see Application Event Log entries from Userenv with ID 1505 (see below)
and other event log entries (e.g. ESENT 488 - see below) that all say
something like "Insufficient system resources exist to complete the
requested service.".
This is a set of 20 identical (cloned from the same image) servers that have
32 GB RAM and 2 quad core processors. No applications are added or modified
after the image is put on the physical server (there are no Virtual Machines
involved in this situation). These servers are running Citrix Presentation
Server 4.5 and are all publishing the same "desktop" - there are no
"published applications".
This problem seems to happen only on a few of the servers for no apparent
reason. Once the symptom starts to happen on a particular server, it
continues to happen at least until most users have logged off. Users that
are already logged on experience no symptoms - they can continue to work
normally. But new users that get assigned to the problematic server by the
Citrix load balancing algorithm get the message that their profile can not
be loaded.
When this problem happens, we see that the Performance Counter:
System
% Registry Quota In Use
is > 99% and sometimes 100%.
The other counters that we usually monitor show no abnormal values (%
Processor Time, Avg. Disk Queue Length, Committed Bytes, Total Sessions),
either on the servers with the problem or those without it. In fact, they
show that these servers are being used, but are not "heavily loaded" - e.g.
% Processor Time is generally below 30%, Committed Bytes is 20-25 GB (out of
32 GB RAM) and 22-27 user sessions.
Now, KB article http://support.microsoft.com/kb/292726 says " there are no
longer any limits on the total amount of space that may be consumed by
registry data (hives) in paged pool memory, and in disk space."
So, what is this "Registry Quota" that the counter "% Registry Quota In Use"
is referring to? We can not find any explanation, beyond what is in the
"Description" of this counter in Performance Monitor. There are many pages
on the web that quote this description, but none that we've been able to
find that explain what "Registry Quota" is being measured against, how to
change the maximum value of this (if it is possible) or to find out why this
counter might go from it's "normal" value of < 25% to 100% (or near) and
stay there.
Although the references we have been able to find about this counter
indicate that it doesn't "have meaning" in Server 2003, we've observed a
very high - essentially one to one - relationship between a very high value
(> 99%) for this counter with occurrences of the symptom.

It is perfectly useless to know the right answer to the wrong question.

anymore.
We've since found a solution, which is to set the registry entry:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\RegistrySizeLimit
to hex ffffffff.
Since making the above setting on all the Terminal Servers, we have not had
this problem again.
The symptoms were:
1. when logging on to a Terminal Server, the user gets told that their
Roaming Profile can not be loaded
2. Performance Monitor shows that the % Registry Quota counter is at 100%
3. Application Event Log entries:
Source: Userenv
Event ID: 1505
Description: Windows cannot load the user's profile but has logged you
on with the default profile for the system.
Detail - Insufficient system resources exist to complete the
requested service.

suck to high hell! If Microsoft is going to abandon NNTP in favour of
incredibly awkward and clunky web forums I suspect that many of the
helpers and respondents in these groups will stop participating in the
online help groups. It won't be the first time that Microsoft misreads
public opinion... Excuse me for voicing my opinion but at times it seems
that Microsoft has a knack for deliberately annoying its customers!

people/department/team in Microsoft are abandoning newsgroups.
For a completely unrelated issue, I got the same message and actually posted
in the (Group Policy) forum to get help with an issue. My experience with
those "Forums" matches yours - slow, clumsy and very inconvenient!
Hopefully, some of the MVPs, such as you, will be heard and someone will
come to their senses! Microsoft really needs to listen to their customers
and those providing (free) help to those customers about this.
Not sure why Mervyn actually posted in this thread because I'm posting a
solution, not a problem!
