I have a strange problem with iis 7. I run my client from a computer no 1 - everything works fine. Then I run it from computer no 2- then it doesn't get contact with BOS at all (404 error I think it was...). Then I rerun the client at computer no. 1 - then it doesn't work here either. Then I retry the same after some hours, but in the opposite sequence - then the same thing happens: the first client that connects succeds, but any other client breaks the whole thing.
I have checked the IIS application pool - it is still running - no errors at server, and nothing in the Debuglog.
I have also checked that machinename in web.config is correct.
I am running the application pool as a classic asp.net pool.
Everything works fine on all IIS 6 servers though..but not on IIS 7.
It seems to me like the singleton object is dying...
