Thanks very much for the reply

I have verified the following in those systems

a) OS ver - Same as mine
b) Office Ver.- Same as mine
c) Highest loaded .NET framework. - Same as mine (4)
d) Group access policy's - This one I do not know what all I need to check, as this is managed by system administrator.

As you suggested, I had a quick view on MDAC, which says that there are 3 modules for Jet. But any way I cannot check the difference between the dlls in my system and their system.

What Group policy should I check to verify. Thanks in advance
