DNS timeout / intermittent website loading problems with cisco routers and Windows DNS servers.

I have had connection issues with RV042, RV082, and now RV180.  I think I finally found the cause to be a feature used on Windows 2008 R2 and newer that provide DNS services.

The symptoms are:  intermittent problems loading web pages, slow loading pages

 

The cause in our case was a feature of Windows DNS server that potentially conflicts with some firewalls.  This Microsoft knowledgebase article describes the issue and the fix:

 

Some DNS name queries are unsuccessful after you deploy a Windows-based DNS server

I hope this helps others that have been pulling their hair out looking for a solution.  And hopefully we might see future firmware updates that fix this issue on cisco's routers or provide a way to make adjustments as discussed in this support article.
