PWA from Internet: msadc error

[Alexander Baidin]

Installed Project Server 2003 on Small Business Server 2003. Everything
(WSS, Project Professional, PWA) is OK while working inside corporate LAN.
Configured web access from Internet to corporate WSS resources (locally
accessed as http://companyweb).
Configured corporate web site on the same server that is accessible from
Internet- http://mycompanyname.com.
So far so good. Then configured ISA server so that it enabled access for PWA
users from Internet to Project Server
(http://mycompanyname.com/projectserver). Login works. I can open home page
from Internet (http://mycompanyname.com/projectserver/home/homepage.asp) .
But when I click on Resources menu I get error message from VBScript
Microsoft Office 2003 Web Access that tells about incorrect DSN at Project
Server

I can see the following in IIS log:
....SBS - www.mycompanyname.com http POST
http://192.168.100.1:85/msadc/msadcs.dll/PjBusObj.PjTaskBusObj2.BOGetProjectViewRS
Inet 404

....ACTIVEDATA htttp POST
http://www.mycompanyname.com/msadc/msadcs.dll/PjBusObj.PjTaskBusObj2.BOGetProjectViewRS
Inet 404

Looks like there is some prohibition for msadc.dll to save anything. I am
not sure whether IIS or ISA server prohibits it.
May be I have to Run the Web server in an unsafe mode (KB 837981)? Or I
missed anything in user rights assignment? Or in ISA server configuration?
