Can't install Exchange Gateway

[tmm]

I can tell you it works with W2K3 R2 SP2 , EX 2003 SP2 and an store.exe update.
The import thing is, set the security pat, describe in the documentation for the installating user first (use adsiedit), then install the gateway and it works.

second thing, do not try to run the gateway again an linux based gwise domain.
I setup on the ex 2003 an secondary domain on windows only with the gateway

one problem we have, the appointment exhange work, but if somebody in exchange accept, gwise does not recognize.
any idear ?
