RpcServerUseProtSeqEp() Call Causes Local Named Object to Be Created in Global Name Space

• Microsoft Windows NT Server version 4.0, Terminal Server Edition

SYMPTOMS

When developing an application to run under Windows Terminal Server, a call to the RpcServerUseProtseqEp() API may cause any subsequent named objects to be created in the global name space versus the name space of the client user. Any Win32 API which creates names objects may be affected if called following a call to RpcServerUseProtseqEp().

For example, if a named pipes application were to create an event object using the CreateEvent() API following a call to the RpcServerUseProtseqEp() API, the event object would be created in the global name space instead of the preferred local name space of the Windows Terminal Server user. If the named object is created before calling the above offending RPC API, the named object is created in the correct user name space.

CAUSE

The problem is that the RcpServerUseProtSeqEp() API does not properly restore the user environment when returning from kernel mode.
