Revision History:
|
|
|
|
At this point - the following features of the IIS5 code base are
|
|
considered obsolete (ie never to be part of IIS+):
|
|
|
|
1. Service control manager goo
|
|
2. RPC administration support
|
|
3. Down-level admin support
|
|
4. Socket/Endpoint goo
|
|
5. Direct handling of site - start/stop/pause/etc
|
|
6. Password change support (ie. .htr hooks).
