Run-away svchost.exe

I have a svchost.exe that grows by about 200K per
second. I ran tasklist /svc and it hosts LmHosts and
SSDPSRV. I have isolated it to only LmHosts by editing
the registry and it exhibits the same behavior. I cannot
find any article in the knowledge base similar to this
problem, so I am asking for help here. There is not a
lmhosts file on my computer. The file seems to be living
in memory. If I end the process via task manager,
everything seems to run ok. I would like to know how to
stop the svchost.exe from growing and, if possible, know
why it started in the first place. Please reply to the
newsgroup since the email address is my MSDN alias.
Thanks, Vik.

LMHosts is used where you have NetBIOS support implemented over TCP/IP -
which *might* be needed in a LAN connection, but certainly is not on an
Internet one. So you can probably turn it off with advantage. In
Control Panel - Network Connections - r-click your connection and take
Properties. Highlight TCP/IP and click Properties; in that click
Advanced and look on the WINS page

There is a box 'Enable LMHOSTS lookup' - uncheck it and Apply

Also probably select 'Disable NetBIOS over TCP/IP' if you do *not* have
a connection to a LAN where other machines may be using NetBIOS
 
Thank you for your reply. I tried your suggestions and the problem
continued. I edited the LmHosts from the registry and every thing seems to
be working ok. I am still very couious about why the "memory leak" in the
first place. Again, thanks for your help, Vik.
