How to go directly to the work item in CRm 7.0

Hi

http://xxxxvdc2s.eu.xx.xxxxxxx:8000/sap/crm_logon?sap-client=200?default.htm?crm-object-type=WORKITEM_IB&crm-object-action=B&crm-object-keyname=WI_ID&crm-object-value=26120

This is above the url which i am passing .Its not directly going to the work item.

and also the client is filled with 200 ?default.htm which is wrong.

if i am using http://xxxxvdc2s.eu.xx.xxxxxxx:8000/sap/crm_logon?sap-client=200? then client is not filled with any thing its properly logged in but here i have to go through all the steps to reach my work item.

if i am using http://xxxxvdc2s.eu.xx.xxxxxxx:8000/sap/crm_logon?default.htm?crm-object-type=WORKITEM_IB&crm-object-action=B&crm-object-keyname=WI_ID&crm-object-value=26120

then here its defaultly taking 100 as the client instead 200.

so any body please help me in CRM 7.0 how to login directly to perticular client and go to perticular work item?
