What is MSSRPD?

Recently, I found that some searches in Firefox are redirected to Bing. (Instead of my primary search engine Google.)

I am not sure, but it seems that it is not bound to search but rather a hostname resolving. Since entering a single word that might be a hostname redirects to Bing. But entering more words searches using my primary search engine.

hey -> uses Bing to search

hey hey -> uses Google to search

I found that the resultin开发者_开发知识库g search url contains MSSRPD:

http://www.bing.com/search?q=hey&form=MSSRPD

I am wondering what is the MSSRPD and how can I uninstall/disable it, so my primary search engine is used?

EDIT: I have no directory C:\Program Files\Microsoft\Search Enhancement Pack\Search Helper\ on my computer.

EDIT2: Same problem in Safari.

I found the answer: In case you have the same problem, go to registry: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\TCPIP\Parameters and empty the mshome.net value from the ICSDomain key, then disable and re-enable your network adapter.

UPDATE: After few days, it stopped working again. I've found that IPv6 DNS is also redirecting to Bing. I don't know, where Windows get the IPv6 DNS since my DHCP server is not providing that and I have not set up that. So, I've disabled IPv6 for now and it works.

I got the exact same problem. I think the problem started when I installed Daemon Tools Lite but I'm not sure.

I used the Sytem Restore thing and the problem disappeared.
