После установки KR2 на AX3 SP3 не пускает на AOS больше 100 пользователей

Вы уж меня простите если грубовато получилось, но это самый что ни на есть RTFM

AOS Enhanced Stability and Logging
Registry Keys have been added for the purpose of tightening configuration when the AOS is in a low resource scenario. If these limits are reached, the AOS will reject new connections. If these keys do not exist, or if they exist without a value, Axapta uses the default value listed for each key. If enabling this functionality, configure each key for each instance of the AOS running.
\HKLM\SYSTEM\CurrentControlSet\Services\Axapta Object Server\Applications\<AOS Instance Name>\3.0\<AOS Config Name>
These keys may be replicated to the CurrentControlSet001 and CurrentControlSet002. See Microsoft Knowledge Base article 100010, “What are Control Sets? What is CurrentControlSet? (http://go.microsoft.com/fwlink/?LinkId=59068)” for more information on Control Sets.
Note: The registry settings may have to be set for each control set for each AOS instance configured. This may not be a one place registry change.
The following table lists the default values, which are also the recommended values. Note that they are string values.
Reg key Type Default
MaxConcurrentSessions REG_SZ1 100
MaxMemPercentage REG_SZ1 50
MaxConcurrentSessions
Set the value of this key to the number of concurrent sessions that you want the upper limit to be.
MaxMemPercentage
Set this value to the percentage of memory that you want the AOS process (ax32serv.exe) to use. This total memory percentage includes pagefile.

На форуме тоже где-то обсуждалось. Наверняка можно найти в поиске.

Кстати, более 100 пользователей на один АОС — многовато, IMHO.
