Thanks for your help.
Client/Load Machine Specifics:
Windows 7, 64-bit, w/ SP1
i5 CPU 2.67GHz, 4GB RAM
WAPT Pro 2.5, build 5/18/12 w/ ASP.NET module
Server running at remote location that we are contracting to
I had IT check router/firewall and they say the requests are not being blocked (they say the requests are logged as potential w/ warning, but not blocked)
IT checked server performance and says server doesn't appear to be at critical load
WAPT SNMP counters indicate server performance criteria is OK.
Ramp-Up from 2 to 10, w/ step 2 every 12secs for a run-time of 01:00
For this test, I only selected to run 1 profile
I've tried increasing user-think time for the first request from (0 to 1) to (5-10); less sessions (expected), but still get network errors
I've tried setting "Server response valid if response time is less than" to 5000 and 10000 (5sec & 10sec); no affect
I've tried changing the "Wait seconds after session failure" from 1 to 5secs; less failed sessions (expected, but still get network errors
I've turned on and off the "Keep alive server connection" with no affect
