A DCOM program (the client) that requests the creation of
an object on a computer that is running any of the following operating systems
may stop responding (hang):
- Windows 98 Second Edition
- Windows 98
- Windows Millennium Edition
This problem can be caused by a bug in the processing of
request in the RPC layer that may cause the server to incorrectly interpret
that the unsecured bind request has already been processed.

Microsoft
has confirmed that this is a problem in the Microsoft products that are listed
at the beginning of this article.
A network trace of the event shows that the client is
sending a secured RPC bind request that is rejected by the server (because
those versions of Windows do not support that type of binding). The client then
sends a request for an unsecured RPC bind. The receipt of the unsecured RPC
bind request packet is acknowledged by the server at the TCP layer, but the
actual request is never acknowledged or rejected by the server at the
application layer. The implementation of the DCOM client has a 100-hour timeout
for the completion of the bind request, so this is what causes the program to
hang.
