Microsoft does not recommend to use Office Interop in server settings:
http://support.microsoft.com/default.aspx?scid=kb;EN-US;q257757#kb2[^],
http://support.microsoft.com/kb/257757/en-us[^].

I would advise to use Open XML SDK instead:

Thanks for the links,
Have a doubt, is it possible to convert word document to html using Open XML SDK with same format(font,color,font size).
Can you please help me by providing any link for that.
I try to solve this issue from past two days.

Thanks in advance.

There is no one-to-one correspondence. You can only make HTML look like your source document, more or less.
Actually, you inputs comes in two parts: one is the DOCX file, another input is some set of mapping rules you want to build to meet some requirements. It is up to you how you formulate them. This is actually a very usual feature of some sites, such as job-search sites where users submit resume documents. I don't know any particular source code samples, but I'm sure you can find something...

I don't have any links. no more than you could have. The remaining problem is not a problem which can be solved by one more expert advice; this is just the work to be done, and the work which requires considerable time. As you did not explain where your difficulties are, I don't know what to add...
