Strong name for dll??

Heya,
I'm trying to create a strong name for a dll that I purchased. The dll is simply a PDF Merge dll. This dll is not something that I created. I want to know is it possible to give it a strong name? I've tried using al.exe (which comes with .net) and sn.exe. But I dont think I'm doing it right? Could someone please help me out. I'm using XP with .net 2003. Framework is v1.1.
The reason why I need this dll as a strong name is becuase I'm using Telstra as my web host and they support a hosted trust level. The only way I can use third party dll's is to give them a strong name...

Thankx in advance

:)Have you referred to MSDN yet?

Yes I have... And thankx for your reply... All help is appreciated...
I believe that the article is refering to creating strong names for dll's that you have created via code. I dont have the code for this dll. I purchased it. I only have the dll. So my question is can I give it a strong name still or do I have to have the code as well?

Thankx again in advance

You should have Code for Giving it a Strong Name.
Yes, I've tried to create a strong name once for a third-party DLL, but simply couldn't because I didn't have all parameters ready.
So any ideas on what I should do? Or what I could do?

Thankx again...

Ask your web hosts to install it for you?
Thankx for your help... I will see if my web host will agree to that...
Thankx again
