Tip & How-To about Microsoft Windows XP Professional

Disable UPnP and SSDPSRV Services to increase your PC security

Windows XP includes support for Universal Plug and Play (UnPnP) which allows UnPnP devices to be connected over a network. Also the SSDP Discovery Service (SSDPSRV) need to be disabled also as shown



There are currently limited UnPnP devices available and due to a recent security flaw it may be advisable to disable these two services. Download THIS tweak and then restart your PC it will set both to DISABLE (0x4)

NOTE: These two services can also cause your Task Bar to malfunction and remove your icons from the righthand side so disabling them will prevent this from happening as well

Hello, no it shouldnt make any different. but if you disable it you can get some problem with your msn if you have your router as NAT. also you can get problem with your external storages devices.
I recommend that you have the service running.

d-link dir-300 router always rebooting/restarting


This is the fix from d-link:
Router rebooting itself print.gif You may be experiencing trouble with a feature known as UPnP(TM). This feature allows Windows XP and Me machines to remotely open necessary ports for Internet Applications. You may try disabling UPnP (on the router AS WELL AS your computers) to see if this cures your reset woes. Log into the web-based configuration, access the Tools page, then the Misc. button. Choose the disabled button next to UPnP. Click Apply. You should no longer experience the frequent resets.Try disabling in XP first to see if that fixes issue.

To manually disable UPnP/SSDP in Windows 2000/XP/Vista:
  • Go to Start Menu-->Run...
  • Type "services.msc" and click OK
  • Find the service named "Universal Plug and Play Device Host" service
  • Click the Stop button to stop the service
  • Under Startup type, select Disabled from the pull-down menu and click OK
  • Find the service named "SSDP Discovery Service" and double-click
  • Click the Stop button to stop the service
  • Under Startup type, select Disabled from the pull-down menu and click OK

where can i find the settings page so that i can enable the UpNp ??


You can install Universal Plug and Play support in Windows XP by using the Add or Remove Programs tool in Control Panel. If Universal Plug and Play support is installed, when a Universal Plug and Play device is added to the network, the Windows-based computer acts as a control point for that device, and notification is provided on the taskbar that a new device is available.
