windows sharepoint services (WSS) 2.0 configuration issue
===

I have installed windows sharepoint services 2.0 and Microsoft office sharepoint portal server 2003.

Ques1- All I need to do is manage my project documents the very basic directory.Do i need both this s/w at a time for it?

Ques2-After Installing these two s/w, I get SharePoint Central Administration in my IIS->Web Sites

When I right click SharePoint Central Administration -> browse , it shows me 2 links

.Windows Sharepoint Services
.Sharepoint portal Server


**Clinking  Windows Sharepoint Services:**

Shows Set Configuration Database Server Page

**Clicking SharePoint portal Server Gives error:**

Unable to load DLL 'dFastlog.dll': The specified module could not be found. (Exception from HRESULT: 0x8007007E) 
 


How to solve this Issue,pls Help.
