NSI service on Win2008R2 using huge amount of RAM over time

Question

I have Remote Desktop Servers running Windows 2008R2. Some with all the latest Windows Updates, some without. All of them, over time, have a svchost process eat up a large amount of RAM (goes up and up... some after a few weeks are above 1GB).

I traced the svchost process to be the NSI - Network Store Interface Service process.

I found these two things on-line about this but none provide a solution.

One of those post suggested to unplug and replug the network cable - I tried and the result has been svchost process memory usage suddenly climbing (instead of going down as suggested).

Anyone has experienced and solved that?

You are probably running into this: http://answers.microsoft.com/en-us/windows/forum/windows_7-system/nsi-memory-leaks-fixed-yet/f3c3e9db-36a7-45df-9dbd-de9455378498

a memory leak in Windows 7 / Windows Server 2008 R2, introduced when you installed IE10 / IE11.

Workaround until they really fix it: uninstall IE10 and IE11 (and double check afterwards you really have IE9 or IE8). As of now (patched up to 10 July 2014) the issue isn't fixed.
