Regarding asp.net website problem in Window server 2003

Hi i have asp.net application which includes an window control library and i
want to embedd this window control on my aspx page using <object>tag of
html

page.This page is working on machine having operating system XP but it does not
load on machine having operating system Window server 2003.As i have to deploy
my website on server2003.But i develop my website on XP system here i had tested
it working fine in all ways.The syntax of loading these control's is also
different in 2003.

In XP:-<object id='Object1'
classid='WFCRECORDECG.dll#WFCRECORDECG.UserControl1' height=100
width=100></object>

But in Server 2003  <object id='Object1' classid='WFCRECORDECG.dll'
height=100 width=100></object> here it take classid implicitly so when
i pick url from directory as it contains the name of DLL file and if i try to
replace it with classid='WFCRECORDECG.dll#WFCRECORDECG.UserControl1' the it
gives an error that file can't found.So might be there is a path problem
occuring here.Plz give me the solutions.

Thanks in advance.
