help.. converting query from MS Access to SQL

Please help. I have the following query that runs in access and I need to make it run directly on SQL Server 2K. I did not build this access query and I have never used a join quite like this. Any help would be appreciated.

UPDATE tblItm
INNER JOIN (ItmStr INNER JOIN StrReqRvw ON
(StrReqRvw.StNo = ItmStr.StrNo) AND
(ItmStr.UPC = StrReqRvw.UPC)) ON tblItm.UPC = StrReqRvw.UPC
SET ItmStr.StrReqQty = 0
WHERE (((StrReqRvw.ReqDt) Like '11/04/02')
AND ((tblItm.StckFlg)<>"SQ" And (tblItm.StckFlg)<>"PR"));

Thanks

I am not sure if this is exactly what you need because the update query is so out of order. Is this part of VBA code? If it is just a stand alone update query then this should replace it for SQL Server:

update itmstr

set strreqqty = 0

from
itmstr a inner join strreqrvw b
on a.stno = b.strno and
a.upc = b.upc
inner join tblitm c
on c.upc = b.upc

where
b.reqdt like '11/04/02'
and c.stckflg <> 'sq'
and c.stckflg <> 'pr'
