Larry,
The error message your getting is clearly indicating that IIS is having trouble processing your credentials through. If it were SQL server causing the problem you'd probably be getting a different error - which I have intimate experience with (network blocks on port 1433/1434 traffic- this is probably NOT your problem given your error message).
Did you check/add the DNS suffix search settings for name resolution? Regardless of the fact that you're specifying a FQDN in the URL in the project professional connection setting - M$Project somewhere along the way still tries to do WINS resolution. Call it Micro$oft hubris - M$ expecting you to be on a M$ network. I have no M$ network available to me in my building yet I'm successfully connecting to a project server on another network in another building on our campus.
I've also added an entry in the hosts file of my workstation but this is essentially redundant if you do the prior step. If you're interested the file is in C:\WINDOWS\system32\drivers\etc and the entries look like this:
# target IP shortname FQDN
999.000.999.999 server1 server1.my.domain.com
Have you had anyone watch the incoming traffic to your project server while you try making a connection? Your network guys can do this with a sniffer. Tell them the problem you're having and the machine you're trying to connect to and then ask them to set aside 5-10 minutes to watch for you. You may need to have a hole punched in the firewall for your IP address to get through. Even if you're using DHCP your IP address can be made to "stick" to your machines MAC address - in effect giving you a static address.
Also, since you're using SSL have you got your certificates all legitimate? Are you or have you ever been prompted to review/accept the site certificate?

Well you learn something new everyday. Thanks for replying. I didn't know
you could associate a domain\username account from outisde the domain in XP
using control panel. Unfortunately, this disn't solve the problem. I
associated my domain\user account on XP for the
https://FQDN/, made sure
that it's a trusted site with automatically log in using windows account
set. When I go to PWA, I no problem logging in on XP with this account.
I'm not even prompted for UN
W now. But, still get that authenticate error
trying from PP. I can login using PP when I'm in logged into the domain.
The other post was somewhat different highlighting the fact this is all
going through ISA. And it doesn't work using the netbios name either. Some
of the other postings duplicated in the last couple of days were accidents.
I kept trying to post one as new and it kept posting back to the old thread
and then all of a sudden several duplicates showed up as new threads. Yes I
know thse forums are voluntary and certain ettiquette should be followed.
Sorry for that and thanks again. I'm still trying.
