It is really only needed if the Switches have redundant Layer2 pathes
(that's Layer2 not 3),...it has nothing to do with subnetting. The
Switches
will examine the redunant pathes and keep the faster one while shutting
down
the slower one,...the slower one then acts as a fall-back link if the
first
one fails.
Hmmm, it's coming back to me now; it's been a while since I thought much
about certain aspects of networking. Thanks for the reminder. I actually
WILL want STP turned on at some point because if I can get a few extra ports
(I'm nearly maxed out now), I'd like to have an extra link between switches
in case one of those ports goes bad on me, and I'd like to start using the
second NICs
It would help if I knew what "unstabile" meant in the context of this
particular Application and how it is behaving or whatever it is doing
wrong.
Also, does the Application use machine names (Netbios Names) when it "does
its thing"?
Unstable means errors generated by the application. These are not native
Windows errors (Illegal Operation, Memory Errors, etc), but errors that
actually log an entry in a custom event log for that application. In most
cases they blow away the window the user was working in, meaning there's
usually some reentry of data neeeded. There are several known causes of
this specific type of error, but we've addressed all those causes and are
still experiencing the errors. The vendor is really scratching their head
on this one. I don't think the application uses Netbios names, since this
vendor is also an ASP that hosts many of its customers via their online
version of the product. They access their data across the internet using
TCP/IP only. It is a .NET application; we made the decision to run the
in-house version rather than the online version, meaning we have a SQL 2000
server and a web server in-house.
Extensive use of GPOs is a "red flag" to me,...you can create total
nuclear
disaster with GPOs in the blink of an eye if you aren't carefull.
I agree. I've been careful with my GPOs; I know they can become
unpredictable if you go in willy-nilly and jack around with them too much.
I think my next step may be to create a test OU that blocks inheritance of
all policies, and selectively apply only the policies needed to provide
basic functionality. Other details, like application deployment,
configuration of IE, Office 2003, Start Menu, Windows Firewall, etc, can be
done manually. If the errors go away for the users tested, I can then start
troubleshooting my GPOs to see which one(s) are to blame. Does that seem
like a sound strategy?
It's hard for me to imagine a setting or even a bug that could cause the
behavior we're having, though. The errors do not occur consistently; there
are days when a user will have a dozen errors before lunch, and other times
when a user may go two or three days without a single issue. The
unpredictability and inconsistency of these errors is one of their most
maddening aspects.
Other than that, I'd have to see what ideas they come up with later.
Thanks for the reply.
