I have server which runs Windows 2003 (x86) and want to add windows 2008 R2, which is x64.

Is it possible to have them work as webfarm? I have issues with aspnet membership recognition between servers.

I already have machineKey defined at app web.config level, but this doesn't helps

  • Not sure what the problem might be, but we have several clients that use this configuration (using Network Load Balancing) so it definitely will work. – Jim Jun 18 '11 at 19:10

machinekey is not architecture specific - so you have something else going on I'm afraid.

  • I have 2 x86 instances and they are working in pair with same code. – st78 Jun 18 '11 at 20:30
  • That may be true, but honestly it's not bit specific. You can look at the code in reflector. – blowdart Jun 18 '11 at 23:33
  • I end up to upgrade all servers to x64 and now it works fine. So, still somewhere there is specific. For example, GetHashCode() also give different results on x86 and x64 – st78 Jun 19 '11 at 07:31

The machineKey must not be autogenerate - it must be exactly the same at each server.
