Hi All,
We are using Fortinet SSO Terminal server Agent, to help authenticate internet users on our Windows 2016 RDS server.
The internet users on the RDS server have been complaining of randomly having to refresh a page a couple of time before it is displayed.
We have checked the TSA agent logs, and found a lot of log entries like below:
"failed to allocate port range for session xy", xy being random numbers.
Then Under the "Port allocation" section of the TSA Configuration, the "System Dynamic Allocation Port Range" has a default entry of 1025-65534, that is leaving user port allocation range to a very small range: 1-1024 which is easily exceeded by the number of user sessions on the RDS server.
So we suspect that when the Port allocation pool is depleted, the agent fails to allocate new session.
Can anyone explain why "System Dynamic Allocation Port Range" is defaulting to such a big range?
and also is there a way to modify the System Dynamic Allocation Port Range
regards,
Eric
