Question

Re-enable RPC

Asked by: kamarja

Hey Experts,

I disabled RPC in the Services tab because I was trying to prevent the MSblaster and Welcher worm from spreading throughout the network. Now that I have the patch, I need to re-enable it but it will not allow me to
re-enable it. I need to edit the registry to re-enable it. Anybody ever done this before - which value do I need to change? Thanks in advance.

- Ian

Hey sgdought,
What does this do ? Kill the service? just curious.

"Image Path"=%SystemRoot%\system32\svchost -k rpcss


Thanks.




 

by: sgdoughtPosted on 2003-08-26 at 09:51:13ID: 9225509

I would suspect so.

 

by: kamarjaPosted on 2003-08-26 at 10:04:39ID: 9225650

Hey sgdought,

You rock!! It's working now.  I didn't change the "ImagePath" because I checked
a few other boxes in the office and they all had the svchost -k argument, so I
left it there. Thanks for your time.

FYI:

Description of Svchost.exe in Windows 2000
The information in this article applies to:
Microsoft Windows 2000 Server
Microsoft Windows 2000 Advanced Server
Microsoft Windows 2000 Professional

This article was previously published under Q250320
For a Microsoft Windows XP version of this article, see 314056.

SUMMARY
Svchost.exe is a generic host process name for services that are run from dynamic-link libraries (DLLs). The Svchost.exe file is located in the %SystemRoot%\System32 folder. At startup, Svchost.exe checks the services portion of the registry to construct a list of services that it needs to load. There can be multiple instances of Svchost.exe running at the same time. Each Svchost.exe session can contain a grouping of services, so that separate services can be run depending on how and where Svchost.exe is started. This allows for better control and debugging.

Svchost.exe groups are identified in the following registry key:
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\Svchost

Each value under this key represents a separate Svchost group and is displayed as a separate instance when you are viewing active processes. Each value is a REG_MULTI_SZ value and contains the services that run under that Svchost group. Each Svchost group can contain one or more service_names extracted from the following registry key, whose Parameters key contains a ServiceDLL value:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Service

MORE INFORMATION
To view the list of services that are running in Svchost:
From the Windows 2000 installation CD's Support\Tools folder, Extract the Tlist.exe utility from the Support.cab file.
On the Start menu, click Run, and then type cmd.
Change folder to the location from which you extracted the Tlist.exe utility.
Type tlist -s.
