I have followed instructions in above post, and I am still getting time out error. I have also adjusted timeout value in Admin->Servers to "Never".
Senerio:
Running "Push" of clients to remote site, while waiting for individual computer authentication check, the webapp session will timeout, forcing me to restart the deployment process with fewer hosts, wait for them to complete, then add another batch to the list. I can do about 12 hosts this way per batch. This does not scale to a 350 host deployment per session (we have 11k hosts total to deploy).
Solutions off the table:
* Using SMS or SCCM to deploy instead of SEP internal deployment tool
* Using PSExec with batch file of hosts to push silent installer
