BSOD - symtdi.sys, Windows XP SP3, & SEP 12.1.671.4971

Created: 06 Jan 2012

I've received word that some of my clients are receiving a BSOD 2-3 times a day due to Symantec's symtdi.sys file.  However, in looking for more information on this matter I don't see anything in the forums about this so I thought I'd ask.  Here is some details on on what its happening to:

OS - Windows XP SP3

Symantec Client version - 12.1.671.4971
