I'm trying to setup a stress/load test using the WCAT toolkit included in the IIS Resources.

Using LogParser, I've processed a UBR file with configuration. It looks something like this:

    [Configuration]
NumClientMachines:  1        # number of distinct client machines to use
NumClientThreads:     100     # number of threads per machine
AsynchronousWait:     TRUE     # asynchronous wait for think and delay
Duration:             5m      # length of experiment (m = minutes, s = seconds)
MaxRecvBuffer:        8192K      # suggested maximum received buffer
ThinkTime:            0s       # maximum think-time before next request
WarmupTime:           5s      # time to warm up before taking statistics
CooldownTime:         6s      # time to cool down at the end of the experiment 

[Performance]

[Script]
SET RequestHeader = "Accept: */*\r\n"
APP RequestHeader = "Accept-Language: en-us\r\n"
APP RequestHeader = "User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.2; .NET CLR 1.0.3705)\r\n"
APP RequestHeader = "Host: %HOST%\r\n"

NEW TRANSACTION
	classId = 1
	NEW REQUEST HTTP
	ResponseStatusCode = 200
	Weight = 45117
	verb = "GET"
	URL = "http://Url1.com" 

NEW TRANSACTION
	classId = 3
	NEW REQUEST HTTP
	ResponseStatusCode = 200
	Weight = 13662
	verb = "GET"
	URL = "http://Url1.com/test.aspx"

Does it look OK?

I execute the controller with this command: wcctl -z StressTest.ubr -a localhost

The Client(s) is executed like this: wcclient localhost

When the client is executed, I get this error: main client thread Connect Attempt 0 Failed. Error = 10061

Has anyone in this world ever used WCAT?
