lsass.exe goes balistic when LastPass is in use, browser locks up...
Posted on 2014-04-26
I have a customer with an odd problem I have not been able to figure out.
He started using LastPass and is very committed to it. He uses FireFox on his workstation and whenever LastPass is active - either storing new credentials or using credentials that have been stored - the browser locks up for about 60 seconds.
The workstation is Win7-64, is fully patched and thoroughly AV scanned daily. There are no other odd plug-ins or extensions.
LastPass support had me remove and reinstall FireFox and I cleaned out all plug-ins and extensions and did a fresh install of LastPass. No change in behavior - still locks up for a short period when LastPass is doing its thing.
I noticed that during the lock-up that lsass.exe takes as much CPU as possible, and drops off when the lock-up is over.
LastPass reports that this is a recent discovery and their only solution is to create a new user account. I want to avoid that as this user is very sensitive to his user environment and if at all possible would like this fixed in a less disruptive way.
And for the record, I did create a fresh test account on this workstation and tested LastPass in FireFox and it worked perfectly, so the offered solution does work, it's just not a good solution for this user (he's the company owner and I need to take special care of him!)
Which brings me to my question... does anyone have suggestions on what can make lsass.exe and LastPass play nice together? Or maybe there's a way to clean-up/restore/reset/fix lsass.exe?
Your help is appreciated,
