[Mono-list] .NET Remoting and Hashtable

[nemesis35]

Hi,

we work on a project of distributed system where we use the technology
dotNET Remoting. But we have there a small issue.

We have two types of nodes there, managers and storages. They both use the
same method (the method is in dll file - manager and storage have the same
copy of this file).
The method is:


      public void UpdateLastSeen(Node n)
      {
         if (lastSeen.ContainsKey(n))
            lastSeen[n] = DateTime.Now;
         else
            lastSeen.Add(n, DateTime.Now);
      }

// Node n - is our own object
// lastSeen is hashtable (key is our own object Node, value is DateTime)

Problem:
The both nodes - managers and also storage peridiocally call this method,
while one of them works well, another one does somethig different with the
same code. 
For example the topology is point-to-point, one manager, one storage.
Storage updates active status of the manager well, but manager can't
recognize that it has is connected stil the same node - the same storage.
The result is that the manager does not overwrite the time of last seen of
the node storage, but by timer click it adds allways a new entry into the
hashtable. With the same code storage works great. 

No idea where the problem could be, maybe the copy of the object Node is not
the same like in the object stored in the hashtable??
Hope that someone will understand what we tried to explain;) and help.

Thanks a lot
