We run Enterprise on all our servers (2000 though)
We break 4 gig of memory in use a lot.  We have /PAE turned on  and we even
use the /3GB switch.  It's that or heavy paging.  It does hamper your
ability to scale but if you are careful and test and know your limits it can
work well.  Sometimes it's ok to use a box with lots of memory but in other
cases it may be better to have more servers with less memory instead.
Roll on 64 bit.  About to conduct our testing.  Seem like most of our memory
woes will disappear.  Now what to do with 50% of our servers which are not
too old but only 32 bit !!!

Curious,  Why do you need to break the 4 Gig limit on a Citrix Server?  It's
not going to be usable memory unless the application utilized the AWE32
extension.   In addition, you're still limited to 2G of kernel memory with a
finite number of PTEs.   Adding more memory in this case will decrease your
ability to scale.  Of course if you go 64-bit, the limits changes and you
could use Windows Standard instead of Enterprise.

Is anyone using 2003 Enterprise edition and PS4 Enterprise? (Or any version
of PS4? :) )

We upgraded one of our servers to 2k3 Ent edition a month or so ago, as we
needed to break the 4G RAM limit. Ever since we've been having issues with
that server dropping connections, so took it out the loop to experiment and
play with it. We've rebuilt another server just this week to be enterprise
(also for the extra RAM handling) and have found that this one too is
dropping connections! 

They were both fine running 2003 standard and we're puzzled as to why
Enterprise should start causing trouble. The servers are BL35's: one's a
dual core with 8Gb, the others a dual dual core with 8Gb. We have another
two servers which are similar to the first, but running 2003 standard at the
moment with no issues. 

Anyone experience this before, or have a clue what's going on?
