Greg,

I haven't seen that exact error message, but in my experience, the only
thing I've seen that stops Outlook from opening is too many open fonts. Go
figure.

Just for fun, try disabling some fonts (either by moving them out of the
Fonts folder, or via ATM Deluxe, etc.). In troubleshooting this problem
(first noticed with the Exchange client), I noticed that the more fonts
there are, the slower Exchange/Outlook opens until at some point, it won't.
Sure hope that's the answer. But probably not...

Tony

hello...i'm a new subscriber...

i work in a small business where the people don't know a lot about computers, networking, etc., but i've been given the job of upgrading their coax/thinnet peer-to-peer lan to something better...

i've recommended they go right to fast ethernet cat 5 cabling and a 10/100 hub so they won't have to upgrade again...

the situation is this:

there are macs and pcs on the lan, and the pcs use pc-maclan to talk to the macs...their coax cables run through the walls and come out through wall jack-plates on the walls...

my questions are:

1. what happens to my lan when i change the wiring? does it then become a windows peer-to-peer lan or can it stay a mac lan more or less? (they are a graphic design firm which needs its macs...)

2. what is the device that i need to put into the wall so that the jacks are rj-45 not coax?? there are little gray items inside the wall out of which the cables emerge from the wall to the back of the wall-plate...methinks i need wall plates with rj-45 connections on the front and back, correct????

thank you for your help...replies to the list or direct replies are fine.

Absolutely nothing happens to your existing LAN...changing the physical
transport layer merely means, at most, getting new trancievers or NIC's for
the various systems. If the tranceivers on the macs and the NIC's are dual
port, (thinnet and twisted pair) it merely means getting different cables and
maybe running the setup program on the PC's. The higher network transport
layers remain the same. (just everything goes faster ;-)

Well, yes, you have a heckuva re-wiring job. You basically need to replace the
coax (which is probably a daisy-chain) to a separate wire run to each wall
plate from the hub. The wall end terminates in an RJ-45 jack, and the hub end
can do the same, or run directly to an RJ-45 plug into the hub.

This is not the simplest of projects, especially if you have to run a lot of
new cable, you might need new conduit (most fire codes don't like, for
instance, running cat5 wire through plenum spaces without conduit, and if the
conduit originally was small, you might not be able to fit the number of
twisted pair cables you need into it) If you're inexperienced at this I'd
_definitely_ consider hiring an electrician with data line exerience to do the
work, or at least serve as a consultant.

One thing to watch out for. I don't know about the little 10/100 hubs; but our
switches and hubs had to be set to do 10bt or 100bt on each port not
autoswitch...most NIC's today are 10/100, and you can lose the connection as
both the NIC and the Hub get into an Alfonse and Gaston situation. "I'll
switch to 100bt, Oh, you wanted 10 bt, no, after you...no after _you_"
