Error C00D0032 or "The server received invalid data from the client on the
control connection" doesn't have a single solution because the users have
not presented one yet. :\  In a few cases un-checking UDP in the Network
options of WMP helped to fix this.

In most cases a partial information about the issue has been provided, so
it's hard to try and help.  Please answer the following...

--What's the _exact_ link to what you are trying to access?
--Does it occur with any and all web content?
--Does it play in mplayer2.exe? (Start>>Run>>Type "mplayer2.exe') - No
Quotes
--What _exact_ version of WMP and what OS do you have?
--Are you running a Firewall?
--Who is your ISP?  Dial-up or High Speed?
--If you have another PC in your house or place of business of the same
occur?

Remember, this is a peer support group meaning the users (Like me I do _not_
work for MS) provide support to each other.  If an answer isn't presented
here ask Product Support.  Microsoft can't fix things when you guys leave
them in the dark about an issue. :|  So in order for a solution or fix it's
up to you to help your peers find one.  Newsgroup postings don't count when
trying to present an issue to MS, you have to call them.  I know, it sucks,
but that's the way it is.
