Guys We run Windows 2000 with SP4 and 4 gig of memory. We have an application that sporadically does "out of memory" errors It is an in-house developed app and the guys that develop it say that we should add more memory to our servers. (total 6 or 8GB) They have talked about adding the /PAE and /3GB switch to our boot.ini files Something about having an MS tool for the exe that allows their app to address more than 2Gb like exchange Any one have any experience with this and will it hurt Citrix performance or any other side effects.
