client log in times while failed over (sfb on premise)
Hi everyone. I have an on premise active / active paired pool SfB environment. I've noticed that random users take longer to sign in to their client while I have my infrastructure failed over to one p...
The clients will eventually log in well under the 300 second threshold. I'm also fairly certain my DNS entries are correct. I'm looking for what might be causing the client login delay for users homed on the failed over pool.
If you have Windows Firewall enabled on the servers, disabling stealth mode for it helped signficantly for us in speeding up sign in times in both local failover and pool failover scenarios.
Browse to HKLM\SOFTWARE\Policies\Microsoft\WindowsFirewall\DomainProfile, create a new DWORD named DisableStealthMode, and set the value to 1.
Disabling this allows the front end servers where the services are shutdown to send back a TCP RST to the client when it tries to connect. Otherwise, if the client doesn't receive a TCP RST, it will wait 20 seconds before moving on to attempting to sign in to next server.
