U-M's Experience With the OSF's DCE
Strategic Direction
The University intends to use DCE as a key piece of its
strategy to achieve interoperability across a heterogeneous
environment. The first DCE service up will be Security. We hope
to have RPC-based applications running next year. We also intend
to start rolling out DFS next year.
