Help, I've lost my remote object!?

Posted Wednesday, June 22, 2005 4:14 PM by robgruen
So this is the 1st time I've seen this but I guess it makes sense since I only deal with so many things. I was helping someone setup IIS hosting of a remote object but for the life of me I couldn't get it working on this W2k3 box. I kept getting 404 (not Read More...

obj.Equals(obj) returns FALSE? For remoting objects this is TRUE!!! Confused yet?
