hi all :) windows 2003 plone 2.1.3 asp404 (deefault.asp) now all work fine. but this is a problem in windows2003 with Forms e.g login form ,I try to replace zopeserver.open with: openmode = Request.ServerVariables("REQUEST_METHOD") if Request.totalBytes > 0 then openmode ="POST" end if zopeServer.Open openmode, zopeRequest, False but perhaps with some ctrl+F5 works but in first time that I click on login button give me Error500 . is there anyone who knows what I say?and I know that YOU change something in your default.asp , what do YOU change there? thanks alot shahrzad <http://www.microsoft.com/downloads/details.aspx?FamilyID=56fc92ee-a71a-4c73-b628-ade629c89499&DisplayLang=en>
