Error adding solution to MOSS
The issue is that when you do stsadm -0 addsolution -filename "solution.wsp", you get an error message that says "Object reference not set to an instance of an object." even tho you're a SharePoint farm administrator. To solve this problem, you need to make sure Your account is in WSS_Restricted_WPG group Your account has access to SharePoint Central Admin Content database and config database. To find out your Central admin content database, Go to Central Administration site Application Management Content Databases Select the Central Administration Web Application. The content database for Central Administration will be displayed.
