You should forcibly open the word document as read-only...

Microsoft.Office.Interop.Word.Document wordDoc = wordapp.Documents.Open(@"C:\inetpub\wwwroot\WebSite1\temp\random.docx", ReadOnly:true);

See https://msdn.microsoft.com/en-us/library/microsoft.office.interop.word.documents.open.aspx for other options that you may find additionally useful (such as not adding file to the recently used list)
