We run our tests on Windows 2000 Advanced Server, Dell PowerEdge servers. We have successfully run the tests for 1000 clients on other application servers in the exact same configuration so there should be no denial of service involved. Regarding the requests they all come from a single ip address, so it should not be a licensing problem either.
Weird isn't it?
It works fine on Linux but Windows refuses the connections?
I'll have another look at this tomorrow when I've got
more time. I've only got XP Home on my laptop, but
I'll try it anyway ;-)
I found this.
Windows isn't mentioned explicity, but the evaluation
of the linked problem mentions "certains OS's"
I've already found one change that helps to workaround
this problem. I'll see what else we can do.
