Thank you, Nick Neklioudov

>>You don't need to run Autmgr32.exe under Windows 2000 at all.

If i do not run Autmgr32.exe on Server (Windows 2000) , when clients (OS: Win98) create object , there is an errror say "0x800706d9 : There are no more endpoints available from the endpoint mapper".

I also try DCOMCNFG.EXE , but it doesnot help.

I am still waiting for any solutions or explanations.
Thanks
