Welcome to the Esri Forums! You'll get fewer questions and quicker answers if each initial post always includes the exact software you're using (to include service packs of ArcGIS and database software, and the operating system), the exact command or UI tool you are using, and the exact error message you've received (as text in the post).
You might not even need to post if you search on the error message, to see if someone else has already posted a solution.
For software installation issues, you should make sure you're using a supported configuration, by checking the ArcGIS system requirements page (for example, SP2 is the minimum service pack for SQL-Server 2005 at 10.0). [Note: These are generally minimum requirements, and higher patch levels are assumed to work.]
I asked it in esri and they said that its not possible in my current version of arcgis server and arcview...its hard to believe that after spending so much i cant use server capabilities
