MIIS/ILM Error: System.BadImageFormatException
So I had MIIS 2003 SP 1 reporting to me that the format of my GalSync-Extension.dll is invalid. So I tried recompiling it – no luck. Same error. The only MSDN article on this indicated that unmanaged code is being passed to the load method. Through trial and error we found the solution: stop and start the MicrosoftIdentityIntegrationService. If that doesn’t work try a reboot. http://feeds.feedburner.com/IdentityLifecycleManagerilmBestPractices
