Hi,

I have found UPnP to be supported by my router and I want to try it out.
So, how do I enable UPnP on Windows 98?

Actually the exact opposite of what you're asking, but maybe interesting as well:

I have tried your links but unfortunatelly I couldn't find what I was looking for.
The first link contains only a tool to disable UPnP.
On the second there is a hotfix which needs UPnP to be already installed (see below).
And on the last there is a tool that doesn't work for me (Winsock error)
Is it possible to install this UPnP add-on without having to use WinXP files?

You need to search into Mdgx's Update/Patches thread:

Just install the netsetup.exe file from your Windows Xp machine located C:\WINDOWS\system32
and all should work fine the reason is because i think this file is required icsdclt.dll
it works with no problems on my computer.

Hi,
Thanks for all advice.
I have done some research, using the links you provided as a starting point, and I have been able to install UPnP client together with a monitoring/control tool without having to resort to accessing Windows XP installation CD or a computer with Windows XP.

Here are the steps to achieve that:
1. Download "Unchecked Buffer in Universal Plug and Play Can Lead to System Compromise for Windows XP" patch in your language: 
http://support.microsoft.com/kb/315000
2. Uncompress Q315000_WXP_SP1_x86_xxx.exe to any directory you like with WinRAR.
3. Run netsetup.exe from that directory.
4. You will be asked confirm installation and then to reboot.
5. After reboot you will be asked about connection type and computer name.
6. You will be asked to reboot again.
7. After reboot you should see a new icon in the tray - UPnP is installed and working.

I have tested this with uTorrent and it worked.
The file already contains all the updates.

After using the UPnP add-on I decided to share with my experience so far.

Here are my observations:

First of all, the service uses a lot of bandwidth. The service will connect to your router regularly (destination: TCP port 5431). It can transfer up to 200 MB a day to your router. This can cause unnecessary risk if you are using it over WiFi with a WEP encryption.

Secondly, after intalling UPnP addon there are two new processes on the process list - SSDPSRV.EXE and ICSclient - with 15 threads in total - they allocate ~10MB together which is high. Furthermore those processes aren't idle all the time but they eat your CPU time - especially SSDPSRV.EXE - which ate over 1 cpu minute in 2 hours.

Also the service keeps open several ports: 5000, 1900 and 1027 which is not good for security.

The service itself isn't very reliable. It happened a few times for me that it allocated ports when I run certain application supporting UPnP but it didn't always free those ports.

To sum up - it isn't a piece of software that I would recommend installing.

...which takes you back to square #2
